The Best. I've used this app tuner for years and find it to be the most accurate out there. Apple however has advised that the app in its present state will not function with future upgrades of their iOS.....will the developers be upgrading the app soon? I'd hate not being able to rely on the Cleartune app in the future.

Okay. I am not a teacher, or professional musician, I play a guitar for the joy it gives me. This app is great, when it works. It tunes precisely, but suddenly gets stuck on one note. There is nothing I can do to force the needle to move again. It is incredibly frustrating. I went to the App Store to see if there has been an upgrade, but it appears that nothing has been done to repair this in two years. Please please repair this App.

Works great!. This app is a life saver. It is extremely accurate. We have several tuners lying around but I always reach for my phone. I have tuned every guitar I own from acoustics to bass guitars and never had a problem with a note registering. I plug the guitar into my phone when tuning. I have used the iPhone built in mic before and it worked fine as well. Those complaining about certain notes or frequencies not picking up can blame the mic not the app. If you are having an issue like this, try moving the soundhole itself closer to the mic.

Formerly great app. I used to love this app. It WAS beautiful, accurate, and easy to use. But with this first update in years, its become unusable for me. It seems like a hasty and thoughtless update. Even with needle damping turned off, it's incredibly slow to register changes in pitch. So slow that it's useless. The ability to turn the wheel to generate any pitch (such as in-between pitches, outside of the set temperament) is gone, with the disappearance of the padlock at the bottom. Finally, it doesn't force the screen to stay on anymore, so that when practicing with a drone it shuts off after a minute - when the screen turns off. Questions sent to the developer about these issues have been unanswered. As far as I'm concerned, this "update" ruined the app.

Excellent tuner, just two small things I would fix. This tuner is excellent. For the money, you won’t find a better tuner for your iPhone. It’s easy to use, accurate and customizable. It had a pitch pipe setting so you can easily listen to any reference tone you like. That being said, I noticed two small differences from the older version versus the new iOS 11 version: 1. The green needle used to turn green when you were +/- 5 cents from the center of the pitch. Now it’s perpetually green. Please change it back to how it was. 2. The pitch pipe used to have a lock setting so that you could set it to any pitch and listen to what it sounds like in or out of tune. Please bring that lock setting back so the pitch pipe works exactly as it did before. No big deal, just hoping the developers see this review and make those changes if they feel the need to. I hope they do.

indispensable iOS app. Very grateful this app was updated for iOS 11! It has always been one of my most-used apps and I was so afraid I would never have it again after updating to iOS 11. The new update is completely functional, though hopefully just a temporary step towards a version that continues the excellent utility of the previous version. The microtonal tuning functionality in the previous version was peerless, I hope that gets reincorporated into the new version. I’d even be willing to purchase a new version. But THANK YOU for making it 64 bit!

Not thrilled with the update. I’m a musician who likes to put a tuner up on the stand and play through an entire piece of music to check for any intonation issues. With the newest update, if I’m not actively touching the screen, it dims and locks on me, which I find annoying. The only way around this is to change the settings on the phone to never lock, which I don’t want to do, so I’ve essentially stopped using this tuner and gone back to my old Korg. As I’ve used and loved this app for years, this is a huge disappointment. Other than this issue (which is a huge one for me), the tuner is accurate and useful, but the pros aren’t enough to overcome the cons for me at this rate.

Best tuner I've used.. I am a guitar teacher and I use this all the time. It works very well. It doesn't jump around like a lot of other tuners do. Gets you perfectly in tune, and I mean perfectly in tune. It's very easy to use. Although recently the orientation quit working. So if I turn my phone upside down it is upside down too. It use to stay upright all the time. Tech support reply fast too.

Ok, but not great really. Nice tuner.... Sometimes. Sometimes it's stable, but all too often it gyrates wildly trying to figure out what tone it's hearing, as opposed to other tuners which never seem to have this crazy problem. Otherwise nice aesthetic UI, and the chromatic wheel tuner is nice and easy to read. Great for just wanting to know what note a sound is, like for singing. Just wish the dev could fix the instability issues which keep cropping up too often for me.

Love this tuner. I have two tuners that I just bought this one and a 30$ tuner for my guitar. Well after using both I haven't touched my 30$ tuner, I use this for every instrument I own guitar, trumpet, trombone, and tuba and I never plan to look back if you need a tuner this is a great app that I would advise over many store bought tuners. Plus this is equipped with your phone so it's just one less item to carry around with all your band equipment. So all in all I advise this app very precise and usefulo

Used to be perfect. I am a classical violinist and violist as well as a teacher. I also play other instruments for a hobby. This app used to be perfect whether I was tuning a note that had to be perfect, tuning my violin knowing it had to be exactly in tune with other tuners, or tuning my banjo or tenor guitar. Now the wheel flails aimlessly no matter what the needle damping setting is. I’m not recommending this to my students any longer and probably won’t use it any more myself until I see another update and give it a test drive.

Fix or refund, please?. I just purchased this on a recommendation from a fellow violinist. I’m on iOS 12 on my iPhone 5s. The pitch pipe feature does not work at all. I checked settings, restarted my phone, and even removed the app and reloaded it. Nothing. Can you please tell me how to remedy this problem or give me a refund? Follow up: After 3 days of waiting for a response here in the App Store, I decided to try to contact the developer via their website, but all I got after typing in my message and hitting "send" was an "internal server error" message. so I called Apple support, and Apple issued a refund. Thank you Apple for rectifying the issue.

Plz update!!. I can’t believe the incredibly fabulous reviews Cleartune gets, Yet has such incredibly poor support. I am also a big fan and extremeley disappointed to hear there is no update available. I certainly hope this is a temporary issue and that an update is on the way. This is a wonderfully useful app.

Unhappy with update. I bought this app years ago and have used it every day for tuning my students. The wheel is too big now and the graphics more cartoonish looking (more 2-dimensional if I’m correct in saying?). The tuning needle stays green all the time now. It used to turn green only when you had the correct pitch which was visually helpful for my students. A step backwards from the older version so very disappointed. I NEVER write reviews so this shows how very disappointed I am.

Yay, update!!!! And...... Seriously, thank you for the update! I don't know what I would do without this tuner. The best out there, period. Just one complaint about the new feel, the arrow pointer is now green all the time, but it used to go yellow when out of tune. It was an added perk and it would be lovely to have that feature back for the next update. Thanks, again!

Great app, but.... This app hasn't been working since I got an iPhone 5C (hence an OS upgrade). I tried everything to get it to work, and finally tonight I found their Facebook page and the solution. Why isn't it posted here?? It's a great app, but this info should be posted clearly in the app description here. Next, the developers should work on a port of the old application called "Intonation Trainer"--a great program that was marketed incorrectly that I found indispensable for teaching students how to tune chords and intervals and to make an intonation map when evaluating new horns. I think these guys could make a really elegant version. If they edit this page, I will happily add that final star….

Why did you remove features?. This has been my go-to tuner for years. As a music teacher, I was able to use the app on two different devices side-by-side to demonstrate what it sounds like when two pitches go in and out of tune with each other (using the tone generator). The “unlocking” feature that removes the pitch grid is essential to the success of this lesson because the students could see the wheel move farther and farther away from the pitch and compare it with the sound waves they hear (as the waves get faster, the pitches go out of tune with one another). They LOVED it and it was an extremely effective lesson. This feature has been removed, unfortunately, and now I need to find an alternative app. Very disappointed.

too good to be true, but it is true. I have always had trouble keeping my mandolin in tune. The string sets never or seldom ever sounded right to me my guitar, mandolin, dobro and banjo have never sounded so good! I triedClear tune in noisy rooms where other tuners failed, and it worked perfectly! In less than a week, I have scrapped my various clip on tuners in favor of this extremely accurate Cleartune tuner. It is worth the money at several times the price!!!

Wonderful. As a string teacher I use this app on a daily basis and I love it. It hears string bass notes which is super helpful and works well on harmonics as well! Love it. My only suggestion/request is can we add a widget to the today screen/notification bar? I would love to not have to unlock my phone every time a student bumps their instrument and I have to retune everything. That tiny change would revolutionize time management in the classroom setting.

Outstanding Tuner. This makes tuning my harpsichord relatively simple. I especially like the pointer that turns green when you are just a few cents away, and the feature that keeps the tool running for the whole tuning session, so you don't have to keep swiping the iPad screen to keep the device from going to sleep. Outstanding!

Gold Standard!. This is the gold standard of tuners. You can tune a piano with this puppy. I prefer this to many of my high-priced digital and analog tuners that cost hundreds of dollars. I’ve been using this for five years, and I couldn’t count a single thing I could do without in musical performance with my best guitars, short of this one elegant iPhone app. Enjoy! Best of the Best!

Love this app. I play the cello and well it works and it's awesome, I would recommend it for anyone. The ONLY thing was that I wanted to use a G as a drone because I was playing something in G Major so I turned on the G to the loudest volume setting on my iPhone and after it damaged my speaker and now my speaker is basically broken, so I would recommend not putting the volume all the way up if you want to use the tuner as a drone, either that or use other headphones or heavy duty speakers if you want to use a note as a drone.

Ain’t broke, don’t fix it. As a guitar teacher, I have referred so many students to download Cleartune. The update a couple years ago made a great app considerably more frustrating. The green arrow pointing to the exact pitch you’re on used to only turn green when you were perfectly in tune, staying yellow when you were not. Now it’s just always green, which is confusing for my students. I avoided updating the app on my iPad for that reason, but recently was forced to update it finally. I also don’t know why the updated version has a more zoomed in version of the pitch wheel. It was great the way it was, please go back.

Used to be the standard.... This app has been on my devices for years because it was the most accurate and responsive tuner out there for iOS. After the update, it has been unusable and inaccurate. I have no problem using the Polytune on my board, but Cleartune was always nice to have in a pinch, or for an impromptu acoustic jam. I hope they get back to the basics and fix the shoddiness and new design of the app so that it is responsive and usable again. I did pay full price for it at one point.

Great with an iRig. This tuner works great with the phones built in mic on an acoustic guitar. It works ok on an unplugged electric if you hold it really close to the strings, but for electric it really shines when connected through an iRig(I'm sure other similar adapters work fine too). I've used this on iPhone 4, iPad 2, and iPhone 5. My main use is still on my old iPhone 4 which I keep around as a beater for just this type of use. I'm guessing this would have worked fine on my 3G while I still had it if I hadn't killed its usefulness by installing iOS 4 on it which slowed it to a crawl.

Amazing!. This app I could go on and on about how good this app is for tuning. I am a violinist and this app helps tune to the finest sound you can make on you instrument. When I want to tune to a certain string I can lock it onto a certain string and and look at the top of the screen to tune it perfectly. This is a great app and is better than all of my handheld tuners combined!

Great app but.... I've had this app for quite a while now and have thoroughly enjoyed its usefulness. With Apple's recent updates and such the tuner lost its controllability. My needle now dances all over the place and I have contacted the company regarding this and they said they were working on a fix but I haven't seen one and it has been months now. My wife has the same app but hasn't updated her iOS and the app works flawlessly. I'm still waiting for the newest update for the erratic needle fix.

Not loving the update!. I rarely pay for apps, but I bought this one a couple of years ago and loved it. I am a music teacher and have referred many students to this app. However, the update has made it frustrating to use for several reasons. I like the smaller size of the old tuning "wheel". This larger size seems to be more "jumpy" and is distracting. It was also very helpful to have the needle stay yellow until the correct pitch was attained (now it just stays green making more difficult to see when that pitch is achieved). I would have rated the app 5 stars with the old version. I will probably look for a new app to use and recommend.

Pretty good app, but. This app does better than other tuning apps, but it sometimes loses the note from my viola if I'm not exactly in tune. It will spin around on notes that are not even close to what I'm playing. Also, I want to have my metronome on my bluetooth headphones, while practicing my scales and pieces so this app won't hear the metronome sound, but when I open ClearTune, it sends the metronome sound to my iPhone5's external speakers - which is bad.

Great app, lacks features from past versions. I have used this app as my only tuner since 6th grade, however the iOS 11 update removed the feature where you could “unlock” the pitch wheel, allowing you to play specific frequencies through the app. I continue to use the app, however I hope the developer will add this feature back. Also, I feel that the pitch wheel interface is slightly clunky and could use some adjusting.

Maybe 10 years. I have had this app a long time. It has long sent my korg and clip on tuners into the obscure corners of my garage. But… I recently purchased an IPhone 13 pro and re purchased the app under a new Apple ID. I am very disappointed. I am using free turners with better success. If the problems are not fixed by march if 2022, I will change to zero stars if it is possible. I hope that I will get my favorite app back and functional.

Fantastic! Really useful :D. I find that this tuner is very accurate for my trumpet, and the options make it very easy to switch from tuning my trumpet, to tuning my bass for jazz band. Or my guitar when I'm at home. It has plenty of other options I should know how to use, but I really don't, know... Tons of useful stuff for anyone who does know though!!!

Love it, hoping for playback improvement. I have found a lot of great use for this application as I am a double bass player. I just wished that it would allow the playback drone over Bluetooth. As it stands, I can only hear the drones from my tiny little iPhone speakers (bad for low frequencies) or through headphones. If this issue could be resolved it would make it the perfect application for me and I am sure many others.

Very cool. Test your hearing.. I bought it to tune my guitar and to just play with sounds. However, I discovered it is an excellent way to test your hearing. Turn the volume down some and use a good set of earphones to test your hearing for losses. People with hearing loss could actually use this to track the character of their hearing loss over time. Musicians or people who like to listen to loud music could use it to be sure they're not losing hearing as time goes on. Useful.

Great but please update. My music teacher recommended this to me years ago and I love it so much more than the other tuning apps. The only problem is that it needs to be updated or else it may stop working when you update your iOS. Please developers update it otherwise I have to get a lesser app that I don't enjoy as much as this one.

Best Tuner I've Found. Hands down, the best digital tuner I've ever used. Looks good, simple, easy to read, with a phenomenal sample rate..plus more options than you probably know what to do with. I love how I can even tune in non-even temperament. This app is more accurate and reliable than some $20 stand-alone tuners. Well worth the price, especially since you always have your phone on you. Looks even better on the iPad. Good job, developers. Thank you. :)

Hooray!. Finally, a tuner app that works for classical musicians! So many of the most popular tuner applications are for guitarists, so it was really refreshing to find this one. I love the ability to choose key and notation system and adjust the calibration of the tuning pitch. All though I don't do much historical performance, those who do will appreciate the wide array of different temperaments to choose from. The only thing I wish this app had was a better background noise dampener for use during orchestra warm up.

Buggy. I’ve been using this app for a while for pipe organ tuning. Its ability to do temperaments is great, however today when I tried to tune to A415 Neidhardt Kleine Stadt, this preset had disappeared and the A415 setting kept reverting to A440. I’m trying to get an organ tuned for a performance and now I am screwed. Two stars for past usefulness but this is really a problem. I’d say use this app with great caution because it is unstable and features that once worked have ceased to. I wouldn’t call it dependable. Sadly for what I do there is no other adequate app. What are we supposed to do? No app with the temperament features, and the one that has them doesn’t work!! Frustrated.

Not working properly.. I’m using an iPhone 12 pro, and the app has not been working properly. It sometimes responds better to pitches from C5 and up, but anything lower than that it gets stuck or doesn’t respond. I’ve tried downloading the app several times, I’ve changed my case to make there was no obstruction to the microphone, but the problem is still there. Is there a fix for this, otherwise I’ll to use another app. Cleartune used to work very well and was indispensable when it came to baroque temperaments.

You took away the lock/unlock?. I have recommended this app many many times. Tracking is better than most professional hardware tuners. Pitch pipe feature is crucial too! I wish I could still get between notes with it though. Why did the lock/unlock button go away?

Thank you for the update!. Thank You! Thank You! Thank You!!! . I’ve been a professional musician since 1980 and this is BY FAR the best and most accurate guitar tuner I’ve ever used. I was devastated when IOS 11 came out and the tuner wasn’t working. Thanks for the quick update. The temperament function really makes it worth it, too. Ever since I read an article in an article in Disc Makers Blog, I’ve used it regularly. Below is a brief section from that article: James Taylor, in order to accommodate the vagaries of acoustic guitars, tunes his strings flatter than normal. Here is his guide: High E string -3 cents B string -6 cents G string -4 cents D string -8 cents A string -10 cents Low E string -12 cents This tuning method is also great for using a capo. Now, your mileage may vary. Your guitar is different than Taylor’s guitar. Your action may be higher. Maybe you play harder. Maybe you don’t use capos. Try it out and adjust your tuning as need be. Anyway, thanks again! This tuner is the best of any I’ve found in the App Store, and (if you’re a serious musician) is worth more than the price you are charging. Have a wonderful day! -DJG. nyc

Excellent tuner!. Update 2017: This was the app I was most concerned about possibly losing in the switchover to exclusively 64-bit apps for iOS 11. Now Cleartune has been updated to function in iOS 11, and I am greatly relieved. It's (still) an excellent tuner. If you're looking for a tuner, you should buy this one. Previous review: I've had this tuner for quite a while now, and use it to tune multiple and various instruments, from my uke to my piano. It's been very precise and reliable. Highly I recommend it.

Needs Updates. I’ve had this app on my phone for years, multiple generations of iPhones. It used to be great, super handy for practice or any sort of musical question. Sadly, for the past couple years it has started to freeze constantly. It’s like it can’t handle too much noise, just a few things then it freezes and I have to restart the app to get it to work. Seems like a relatively easy fix, no sign of improvement thus far. Obviously an app will never be as good as a physical tuner, but this was at least a good option at one point in time.

Best tuner I have tried - please update. I have tried about 10 tuning apps from the App Store. I keep returning to this one. Simply the most elegant and the most accurate. I'm disappointed that the operating system keeps telling me that this app needs to be updated to continue to work. Hello Cleartune, please update this app to current specifications. I don't want to lose you.

A great tuner. I have had no problems with the tuner, and our band director used it for about 3 years until he wanted a more feature-filled app. (I don't blame him considering that he used his phone to tune, record, and act as a metronome.) As a bassist, sometimes it's hard for me to tell when I'm out of tune, especially on the E string. I have always gotten it down to a T when tuning using this. For guitar and bass players (maybe all string instruments?), my other strings tend to ring out when I tune, and that causes the app to spin pretty badly. As long as all my other strings are muted, it works fine. For those rating it very lowly because it's not working: Have you tried using another person's phone/iPod? I watched a friend of mine use this to tune a piano and his trumpet.

The BEST tuner - hands down!. I tried three others, paid good money for them, settled on one for awhile but I just wasn't happy with it. This one is great - powerful and elegant. You won't regret it. (Update: hmmmm...after the new iPhone upgrade 10.3.2, Apple says this app will no longer work on future upgrades. That's disappointing!)

Updates?. Both this and very sadly Stagepass are not updated anymore for compabillity anymore. This app made me buy an Iphone. Now I have to keep a couple of phones from updating to new ios! Stagepass has been taken off the app store. This is a serious loss! Please save the Stagepass app. It is totally unique and there is nothing like it. The effort is also like no other app out there. Again I am saving a couple of phones just for these 2 apps please don't loose them. Update them! I will pay for the update!! Stagepass is a gem!!

Good. A good tuner app. I've been using it since an iPhone 4 and it has always been fantastic. However recently an alert popped up every time I open it, informing me that the developer needs to update this app to improve compatibility. By the time iOS 10.3 is released, this app will be irrelevant and probably won't even launch until it gets updated to 64-bit support. The future of all good apps. Please update this app so I don't have to buy a new tuner app!

Please add Apple Watch app. More than worth it!. Please please please add Apple Watch support, it would be amazing to have a tuner on my wrist at all times. I bought this app mostly to tune my guitar and mando, but I now use it for everything. This can seriously find the note for any sound. Any instrument (or even not) with a resonating frequency and this thing can tell you which note it is. I am very proud of this purchase, great tool for any musician!

Thank you for the update!!!!!. I never deleted this app before the update and I tapped on it by accident and it opened! I was so ecstatic, Ive never been more excited about an update for an app! No I can resume my practice just as I did before! Thank you so much for updating this wonderful app! One thing I did notice however... I like to play the drone through a Bluetooth speaker so I can hear it as I’m playing a passage, and now it won’t play through my speaker. My metronome does, so this is a little disappointing. But this is a minor thing compared to how great this app is! Thank you again!

Spot on. This app was recommended by multiple musician friends who said they don't even use actual tuners now they have this. Have found it to be brilliant for my Cello.

Happy. I had been using a free tuner app. Ads were super annoying and it seemed like it was very vague and would need to be resting against sound hole. Was hesitant to pay (yeah I know 6 bucks) for an app. This one is super sensitive, very precise and I don't need to put on my glasses to read it. Money well spent.

Now useless. Can no longer open this app and the support page does not allow email to be sent and comes up with an error so there is no way of informing bitcount that this app does not now work on the iOS 9 iPad. I used to use this every day to tune my violin so am lost without this paid for app!

Thank you for the update. Cleartune is my favourite - and to be honest one of the best - tuner apps available on iOS. The short time where it was not available after the iOS 11 update really threw a spanner in the works. However the developer has brought it kicking and screaming into the 64-bit era -and it’s come out looking good! The interface is as “clear” as ever, but the change in font is a nice new coat of paint. If you’re new to this app - get it. If you’re an long time user, like me, this update is just what the doctor ordered!

Bring back the old version. The new update is not as good as the old one, needle response is lagging

Does exactly what it claims. In perfect tune. Does exactly what it claims. In perfect tune

A great app now totally useless!!. I can never understand this.. I had this amazing paid app which worked beautifully and now an update (which annoyingly removed the Unlock feature) has ruined it. It is now completely useless - regardless of sensitivity setting and with the phone right next to my violin, the pointer just seems to arbitrarily flick backwards and forwards indicating nothing! Very annoyed that a fully paid-for app is no longer fit for purpose. It should either be fixed or removed from the app store.

Brilliant. I use this for both my guitar and with my cello and doesn't skip a beat!

Worst tuning up I've ever used. Quite possibly the most inaccurate tuner I've used on my iPhone, constant changing from note to note never staying on the one note even when the note hasn't been changed. Shocking!

Works well. Bought this when my clip on tuner broke. Works well. Seems more accurate than the clip on.

Steer clear. This used to be a truly great app - better than most of the hardware tuners I have, but with one of the recent-ish iOS updates, even on a steady (computer generated) test tone the needle jumps up 25 cents or so and back roughly once per second. The app is now essentially unusable. Very disappointing.

NOT IMPRESSED. I play the double bass when my friends recommended I tried it I paid 5.99 dollars for it but when I try to use it changes from note to note And at the end of the day my double bass still needs tuning and sounds horrible

Great until IOS 11. My kids have found it easy to get their violins tuned quickly. However, this app will cease to work with IOS 11 as it is not 64bit.

New update needs an update. I have been using this app without a hitch for the past 5 years to tune my orchestras and students and it has been wonderful until I updated it. The quality has dropped, the backlight keeps turning off and in turn, the app turns off and it doesn't seem to pick up the pitch as well as it did before. Please fix these issues in the next update.

Back on iOS 11. Fantastic, simple tuning app. I’m glad it’s updated for iOS 11 as it’s a great app that offers a convenient substitute to a chromatic tuner.

Update has ruined app. I've used this app to tune my guitars for years and have recommended it to hundreds of students and fellow musicians. Since the update, it has become useless. It has lost its smooth glide and has become jumpy. I can no longer tune my guitars with confidence. Unless the app is returned to its original functionality I won't be using it anymore. Please fix ASAP!

Very cool. I have had this for about 4 or 5 years. I love it. Recommend it all the time. Just gifted it to a friend again:)

hmm not impressed. everyone in the ensemble that I am in highly recommended this app and it was great when I tried it on their phones, so I had high expectations. I recently just tried to download it and accepted the $4.99 fee but before it even started downloading I got a notification telling me that it is unable to download? I tried numerous times and it still won't download. I am thoroughly unimpressed especially since I payed good money for it 😒

Update IOS 11. This has been my favourite tuning app however it needs an update to be compatible with the new IOS 11

Update!!!. please please please get an update for the newest IOS this is such a good app and it is a shame I can’t use it because of the newest IOS

Very Disappointed. I've used this app for 3 years, very happily, but with the recent update the feature allowing the A4 Calibration to be set with the microphone has been lost. This means that the app is now useless to me. Very unhappy.

Good. Brilliant app but no updates for 5 years

Great app!. I use it a lot for tuning guitar and bass

Latest update is terrible. Cleartune for iOS11 removed the visual cue of a green light saying you’re in tune and a red telling you that you are out of tune. This seems like a fairly big error and I hope it will get fixed. It’s a shame because the app used to be the best one on the App Store.

Great app really accurate!!. Great app it tunes really accurately and is far better than the other free ones! Go ahead, pay for it. It’s worth it!!!

Love It. This app is AWESOME, I use it with my guitar! So good! Thank you sooooooo much. The Chasinator

Great guitar tuner. This app is great and is much better than any free tuner I use it all the time it's a must have for guitarist 😃😃😃 awesome

Good tuner but one major problem. This is a good tuner, but one major problem, plugging in my acoustic/electric guitar on my iphone using Peterson’s adaptor cable absolutely does nothing, Cleartune app still picks up background noises, never have this problem on my iStroboSoft, PolyTune, FenderTune, GuitarToolkit, these app completely isolates background noise when my guitar is plugged in, bypassing iPhone’s built in mic (as it supposed to be) which is the main reason why I use the adaptor cable in the first place to accurately tune my guitar without worrying about background noises, if the developer is reading this, can you please fix this problem, it’s a shame that this is one of the highest rated tuner app and comes highly recommended by a lot of reviewers and guitarists but no one seems to notice this simple but major problem.

Great App. Cleartune is very helpful for people on the go. It works perfectly and hits every note. I use it on a regular basis with no problems. Definitely the app for people in need of a tuner. I believe that it does not work well on iPad, as well as older devices. If you have a phone that is quite out of date, I believe your results will vary. If this is not the case, this app will be a BIG help.

Progressively getting worse. I loved this app and recommended it to all my guitar students, however, I’ve noticed a steady decline in the quality of this tuner. I gave up on the iPad version and I fear I’m about to do the same with the iPhone version. This was the BEST app on the market, please return it to its former glory! Are there any updates on the way?

Handy and easy to use. Brilliant idea and so much cheaper than buying one separately and loosing it all the time. Very handy

Great app. Love this app. Very straight-forward to use. I can always rely on this app. I installed this other tuner but it was never as accurate as this app.

Doesn’t work any more. I paid for this app and it doesn’t work on my iPhone XR. Happy to update my review if they fix it.

Better on iPhone. Got this on iPad and its not as good as the iPhone version recommend only if you play a lot of music/ professional

Rubbish - Don’t Purchase. I read great reviews in this app, so purchased it. The pitch pipes don’t work (no sound plays) so I looked into it. Turns out that it hasn’t been updated for years and the app developers website bounces back, so no chance of support or refund.

Loss of quality since updated. The app has been updated sometime in the last week or two, not for the better. I'm a guitar repairer with a registered guitar repair business and have used this app for the last 8 years to fine tune the guitars because of its great response , accuracy and smooth acting dial and needle features. Since the update, the screen is larger which is ok though I prefer seeing more of the dial like it used to be. As a result of the zoomed/closer dial the needle and dial have lost their smooth action and have become jumpy so that it's harder to read and takes longer to tune. I won't be using it anymore I'm afraid. The designers need to re assess this update pronto.

iOS 11. PLEASE UPDATE THIS SO IT’S COMPATIBLE WITH IOS 11 PLEASE!!! I have had this app for a year now and love it but iOS 11 has decided to be a jerk and so this app NEEDS AN UPDATE

Thanks for fixing. Mandolin tuning is superb. As is guitar. The trick is a quiet room. Best tuner app.

DUMB- NEEDS UPDATE. this app is a great app, however, it glitches whenever I use it. It freezes and does not show the note that you are playing. This app NEEDS AN UPDATE. You can not tune with it as it keeps freezing.

Bring back the old functionality and look. I want the unlock functionality back in the frequency generator. A useful feature when you are basically working in one temperament but want to tweak one note. The old pull down menu was also better to use and much easier to read, and the smaller pitch wheel was better when you want to quickly flip to a different note. I have the app on three devices and I have now made sure that two of them will not update so that I keep the older version.

Developer has finally updated with 64-bit support. This app has served me well for many years for viola tuning. It went about 4 years without an update, and I thought it might not ever receive a compatibility update for iOS 11. But now it's fixed and ready to continue working, hopefully for years to come. It works well and does the job. Recommended.

Great for brass players. Love this app. Have been using for ages now. Great for instruments like brass which need transposition. So glad it’s back for IOS 11. Can delete the other app I was forced to use now.

Issues since update. Used to be the best tuner I had for violin, but since the recent update a few months ago it has been unreliable and slow to adapt to change in pitch which it used to handle quite well. For example, I notice a massive delay between playing a D and an E in on the violin.

Best tuner for string instruments. I’m a classical cellist and teacher. This tuner is awesome and accurate. I teach my students with this app because it has a great display of both the pitch wheel and a left/right display for flat/sharp. Ive found they get the hang of tuning their own instruments and improve their sense of pitch fairly quickly. I also like that I can adjust the temperament depending on repertoire. Great app.

Great, but needs 64 bit update!. Great app, solid performer. However, it will probably not work on future updates of iOS unless the developer updates to 64bit. Please do!

Yay for the update!. We can't really complain if support is no longer available for an old favourite app that we got years ago for a few cents. But what a relief that this superb app is now updated. Fear of losing Cleartune was a reason I've delayed updating my iOS!!

Extremely useful - a must have. I use this app everyday. It just does what it says it does and well. This is probably one of the most used apps on my phone. Thanks!

Thanks for reinstating the lock feature!. I missed this feature and welcome its return. All devices updated.

Awesome. 100% recommend this, I use it for tuning my guitar it works really well. It's also very precise. Buy it!

No sound. I just purchased this app a minute ago and there is no sound coming out it. Is anyone else having this issue? Could someone advise me if I need to click on some button in addition to the power button?

Great Tuner. I’ve used this app on my iPhone since I had a 3GS. Updates are rare and that’s a good thing because there’s really nothing to improve on. Nothing burns me more than a useless update for no reason. It’s more accurate and sensitive than any real tuner you could buy for twice the price or more. Very easy to use. Like virtually all tuner apps that use the internal mic of the device, it will be susceptible to ambient noise in the vicinity of the guitar being tuned. I get around that by laying the tuner directly on the guitar with the mic facing the sound hole.

Great... but. Love this tuner but desperately needs an update. Very accurate but not the most user friendly feature wise and defiantly lagging behind compared with newer tuners out there. Would be great to have an easy pull down menu select for alternate tunings. Just because you create a pro tuner doesn't mean you couldn't include some more intuitive features for the masses. Would make it a five star for me.

Pretty great but one suggestion. This app is pretty excellent but there’s one suggestion I’d like to make: with the ability to make custom temperaments it would be nice to choose the number of notes because sometimes you want to have more or less notes

No updates. Been years since the last update. Will be unsupported soon. :(

Doesn’t work. Save your money!

Used to be great. Cleartune used to be fantastic. Now it locks up frequently. It’s a shame it’s not been updated.

Next version of iOS. Update required?. I recently rebooted my iPad and when I used my tuner at a rehearsal last night it said the next version of iOS won't support this app and the developer has to update the app. I love Cleartune and use it exclusively on an almost daily basis. Should I be worried I will lose it?

Seems to have lost contact with the Mike. Mine seems to have seized up and lost contact with the phone mike, rendering it useless.

Update for ios 11. Needs to be updated for ios 11. Otherwise won't work.

Used to work. Loved it and even promoted to my musician friends. Now it freezes and I cannot reach support. Not updated since last fall. Sad for a paid app. Apple should remove it and all their apps if this is their business model.

Works Well. Great visuals, easy to use. Extremely sensitive. Works in places where there is lots of ambient noise.

Needs to be updated. Last update was in 2012 it looks like. Worked perfect on my 4S. Got an SE, and the tuner needle just keeps moving erratically. Would not recommend for iPhone 6 or newer until they update the app. Worked perfectly on the older phone though.

Accurate. I’ve tested this out to see if some of the negative reviewers here are right in saying that it’s inaccurate, and found them wrong. I tested this to my (in tune) piano, and helps a lot with tuning my violin. I’ll be using the more in the future for sure. Worth the money spent!

App doesn’t work on iPhone 11 Pro Max Anymore :(. Stopped working since the update. Needle doesn’t move 😑😑

Cleartune. Disappointing to discover that this app is already out of date viz current iOS. Why is it still being sold? My advice: don't buy

iOS 11????. Just bought this but told it will slow my phone down because it needs to be updated? Darn. Do I need to ask for my money back...

My ‘go to’ tuner!. I seldom take time to write a review but Cleartune is certainly worthy of one. Been using it for over 3 years. Been playing for 50+. Guitar, mando, uke...Have many app tuners. Cleartune is my favourite. Accurate and solid reliability. I Highly recommend it to all guitar players of any level.

Could use support for Bluetooth earbuds. Works perfectly but I would love if I could listen to the drone with my airpods.

Won’t work with ios11. Any update in the horizon?

It’s freezing. I bought this app buts it’s very difficult to tune any instrument with it because the app freezes I really hope that they update the app or els it’s useless.

Love this app. I was so fed up with high priced battery dead tuners. This is always ready to go on ipad as the battery gets charged because it is so useful for many things.😃 Thank you for making this app available and affordable.

Cleartune. I got this app thinking it would be loud enough to tune my violin, but it has such a weak sound as to be useless. DO NOT GET THIS USELESS APP RBE

My go to tuner!. I've had this app for over a year and it's since replaced my old tuner when it died as I always have my iPhone with me. True that it is very sensitive but it's also very accurate. I'll be purchasing a new tuner again, however this app will continue to be used.

Don’t download. Couldn't figure it out. My harp teacher took a look at it and confirmed it is in no way user friendly. It’s only 5$ but 5$ It’s 5$ wasted unfortunately

Locks up. Great easy to use/see tuner, but occasionally locks up. Very frustrationg

Simply the best guitar tuner. This app is my go-to app as soon as I pick up my guitar. I use it on stage, in the studio and when practicing. It also works great to tune my piano. It picks up the low A note on my piano and pretty much the entire range of my piano. Great work!

Once good, now useless. While once a very effective and useful app, the needle/note readout is constantly in motion across a huge range of notes, making tuning virtually impossible. I thought maybe ambient sound was affecting it, but other tuning apps are not experiencing similar issues. This surfaced after a previous iOS update ( around 8) and continues to date (9.3.5). Not currently recommended. If the issue was resolved, I would highly recommend.

Need a Compatibility Update. I spent money on this app because I need a quality tuner with me, but it hasn't been updated since 2012. Why? Now I keep getting warnings saying that using this app may slow down my phone, and that the developer needs to improve its compatibility. Please look into this!

Jesse Pinkman. Great app. Works fine. Worth the money

Needs an iOS 12 update. Used to be the best tuner I’d ever used, but extremely unstable in iOS 12. Needs an update bad, constantly freezing.

Stopped working properly.. Used this app for a long time and loved it. Was always spot on and very easy and quick to use. Recently upgraded from iPhone 5s to a 6 and its not accurate anymore 😐. Takes for ever to tune as the needle constantly jumps all over the place. Don't know if it's the app or iPhone issue now. But it seems every iPhone upgrade something else doesn't work. Won't be getting another one next!

Doesn’t work. Doesn’t do nothing all all, nothing moves I want my money back

Stopped working.. Needle does not move. Does not respond to any sounds.

A shame. It used to work very well… but now it’s not working at all… It’s a shame

My god, finally!. 64 bit update! Finally I thought this app was totally depreciated. Thanks for this :-) best tuning app by a wide margin.

Reads everything flat. I’m disappointed in this tuner. It came highly recommended, but I’ve noticed it picks up and registers every note as slightly flat as compared to every other tuner I’ve got. I’ve checked it against several other tuners, and while the others all give the same readings, this one comes in flat. Pretty useless as a tuner if you ask me.

Does not work anymore on iOS 11. Good, until I upgrade to iOS11. Doesn’t work anymore

Best tuner I’ve found. Love it. Accurate, easy to read, responsive. Wish the light stayed on a little longer.

Once was great. This once was a great tuner but sad to say but under iOS 12.2 , on an iPad mini, this app crashes as soon as you give it audio .

Fantastic but screen goes dark. This app is amazing and I use it all the time, in teaching and my own practice. Love all the temperaments!!! But please please PLEASE do something so the screen doesn’t go dark while the app is in use! It’s frustrating. Thanks!

Update already!. Loved this app since I bought years ago, perfect for practicing, perfect for helping my students, was definitely 5 stars. But it hasn’t been properly updated in several months (not sure what’s up with the ever-recurring “2 minutes ago” update.) It’s slow, no longer does the red/green triangle thingy, please update, I miss using this app in its former glory!!!!

Great app. I am told that it will not work unless updated for latest iOS of iphone.

Love this app. It's always spot-on and works better than most actual tuners. You know it's good when the updates are for nothing but display support.

USED to be good.. This app was good at one time, but it has been YEARS since their last update. With each OS update, there are more and more bugs that do not get dealt with. Definitely worth the money to go with a different app.

64-bit update needed. Fantastic app, but it hasn't been updated in 4 years and won't be compatible with iOS this fall if it isn't updated for 64-bit support.

Not great anymore. Used to be a great app. Now it just does not seem to be hearing frequencies anymore. The needle does not move half the time, especially for low frequencies.

Can we please get an Apple Watch app extension?Pretty please?. Thank you.

Review.. I love your app! A use it all the time but the new update is super glitchy. Try and fix it cause your app used to be fantastic!

Need update. PLEASE UPDATE...!! Update no working on iPhone 6s+

Great in the past, terrible now!. Use to be the perfect tuner. Not updated so laggy and occasional freezes. Shame.

Needs to be updated…. Cleartune is well-designed, is easy to use, and is precise. However, when I open it on my iPad Pro, a message pops up: "'Cleartune' May Slow Down Your iPad. The developer of this app needs to update it to improve its compatibility." If updated, this would receive five stars. Even if it works great on the iPad Pro, I'd prefer not to have to deal with the persistent warning message.

What happened?. Until the latest version update, this app was my go-to app for checking intonation while practicing violin. With the newest version, it seems far less responsive, even “ignoring” pitch changes. Possibly the additional noise filtering has dumbed its down too much. I think I liked the old version much better!

Good, accurate - but. Would give this 5 stars, but with one of the updates they removed the auto calibration feature. I use this app to tune pipe organs, and because of frequent changes of temperature and air density, the need to recalibrate is frequent. As far as accuracy goes, it’s the best for securing an equal temperament.

THE BEST TUNER!!!. Anyone needing a REALLY good tuner needed look no further!! This one has all the functions and options required to tune any instrument with speed and great accuracy. I've been using the app for about 2-years and figured I should this app the kudos it has earned in real world use!!

Pleaaassseee update!. I just updated my phone to iOS 11 and this is by far the best tuning app I have ever used. I would love to continue using this app but it won’t even open on my phone anymore. Help a girl out, friend. 😞😞😞

Love this app; Thanks for Updating!. For people using this app - I really do love it and it's been great for tuning my guitar and bass guitar. As a full time IT professional I appreciate this App being updated so I can use it and update to iOS 11 to get the security patches. As a musician I'm glad I can keep my guitars and bass in tune. Rock on!

Needs update!. This has been my tuner of choice for years now, but it is going to need an update to run in future versions of iOS. A few weeks ago I sent an email to the developer asking if it was going to be updated, and haven't heard back. I'm looking for another tuner now, in case this one doesn't get updated.

Precise.. probably the best portable yuner i've found for trumpet. Very precise. Different tuning options which is great if working with strings, etc. Since the recent upgrade, the screen is not rotating. 5stars because i'm counting on that getting fixed.

Best Pitch pipe app by far. I’ve used Cleartune for years before iOS 11 since it has by far the best pitch pipe/tuning drone interface of any app I’ve come across. I was upset that after iOS 11 I couldn’t use it anymore, but after the update today I’m more than happy to give it 5 stars!

App used to be amazing.. what happened?. This was once my favorite tuning app. Now it freezes on the regular and lags when I try to change tones with the tuning dial. How frustrating! What happened Cleartune developers? I'm using an iPhone Pro Max and this app acts like it's struggling. I wish the developers would fix the app to work like it used to back in the day. I guess in the meantime I'll just delete it and find a replacement.

The only tuner I'll use now. I bought this app in 6th grade when I started to play clarinet, and now I'm in 10th and play guitar. In between that, I've played trumpet and all sorts of other instruments, and all of them have been tuned best using this app. In fact, it's the only tuner I use now, and I always have it nearby.

Works great, easy to use with uncluttered display. I purchased this after buying another app that was inaccurate and useless for tuning my harpsichord to historical temperaments (Kimberger, meantone, Vilotti, Werckmeister). This one works correctly and the display is easy to read and uncluttered. Highly recommended!

Great. I use this to tune my harp all the time. Multiply 40 strings times 3 times a week and you'll get how much time I spend with this app. For those that complain about spinning, there are needle damping options which settle the sensitivity....an issue I only find in the higher octaves.

Farewell Old Friend. I have used this app daily as a performing musician and music educator for 7 years, and it has always been my first recommendation for all of my students. Unfortunately, I cannot find any indication that the developers will continue to support their product. I would pay for the updated version that will support my devices into the future, but I'm already looking for my new standard iOS tuner.

My favorite app. I've used this app since it was first released. I've had many guitar tuners over the years (from cheap ones to very expensive ones)...but this is by far my favorite! Definitely recommend!

Get this. This is the best tuning app I have ever used; I bought many before clear tune. It can be super simple or very complex depending on what you need, full customization of temperament which is a big deal for major musicians

I Love This Tuner!!. This is by far the best tuner I've found in the App Store, or anywhere else for that matter. Please, please, PLEASE update this app! I do not want to switch to an inferior app when I update to iOS 11! If I have to lose this, my recommendation to use this app goes away as well.

Thank you!. I am a string teacher and I use this app daily to tune my students. Only flaw is that it can not read an open E string on the double bass (both iPhone and iPad editions), but it works when I play the harmonic. My students think its the coolest thing ever. :)

Screen darkens after a few moments. On the one hand, this app has a handsome, easy-read screen and it seems accurate. On the huge downside, it doesn’t force the screen to stay on. Every few moments I have to stop tuning, touch it, and start again. I’m forced to look for a new tuning app.

Update your app please. I've been using Cleartune since my iPad 3 it's been on every single one of my Apple devices, but has become clear that the developers have moved on or are uninterested in updating this app. Please update this app for newer operating systems so it won't just stop working. It's been a real pleasure using Cleartune and I hope to continue doing so for a long time.

not just best app tuner - best TUNER you can get. This tuner out performs every tuner I've ever used. Better than a stomp box tuner, better than a rack mount tuner, better than a waves plug in tuner. And that's just the "tuning" part. The features are crazy and actually useful. Guitar mode is incredible. This is indispensable for recording sessions, live performance…really anything where being in tune really matters. But the fact that this is an app that you always have in your pocket makes it even better. Can't give enough stars.

Don’t waste your time. The devs removed features a few years back, and never added them back in. No updates in years, and it may not even work on all devices. Plus it just doesn’t pick up quieter sounds very well, such as an unplugged electric guitar. Plain and simple, other apps work better. Cleartune was great when it first came out, but it has languished and isn’t worth using at all in 2023.

Good app but..... Overall this is a very useful app but I have been unable to find a way to disable auto lock when using it. It is quite annoying that it shuts off unless I disable my auto lock every time I use it. Not sure if this is still being supported as I have been unable to contact their support.

Please Update!. September 19th This wonderful tuner is the only one in the App Store that really works and that I know I can trust. It's really accurate and easy to read and understand. Today I just found out by looking in my settings that this app is not compatible with the IOS 11 update. I was really disappointed by that because I need this app to tune my instrument, and it's hard to find a really good tuner. Could you update its compatibility please? September 27th OH MY GOODNESS!! Thank you guys so much for reading and listening to my review. I really appreciate you updating for IOS 11 and y'all are the best tuner there is! Thank you so much!!

Cleartune. This app works just as described on my iPhone using iOS 10. Now I have upgraded my iPhone to iOS 11, and I can’t use this app until the developer updates it. In just one day Cleartune went from being one of the most useful apps to mere garbage. Please update this app!

Best Tuner Ever. Well worth the money for me. Very accurate and has been on my phone for years. Im finally writing a review after telling a friend. Great benefit to being in a guitar store, jam session, or bonfire and having this handy.

Best tuner I've ever used.. And that includes standalone units. And I when I say 'best', I do not mean it is the tuner with the most features (though this one does have tons of features), but simplest and easy to use. Also functions as a pitch pipe, playing any note.

Fast, smooth and accurate. It is very flexible and uses the microphones to isolate the sound of the instrument. It quickly switches between notes and is easy to use. Works great for a banjo, acoustic and electric guitars. Works better than cheap stand-alone tuners

Still the Best. I got this tuner app maybe seven years ago and it is still the app I go to when I want to tune my guitar. No bells and whistles and the interface is downright retro but it does exactly what I need it to do every time I need to tune my guitar.

The best for James Taylor tuning. I watched a video by James Taylor on how he tunes his acoustic guitar. In order to follow his method you must have a tuner that easily displays cents while tuning. This tuner does that and is very accurate. I now use his method of tuning and my fingerstyle guitar sounds so much sweeter.

Used to work. I used to use this often- with the phone always in my pocket this app was great for checking the key of something quickly or as a back up tuner. But lately it is always frozen. Doesn't have to be a noisy environment, can be a long note in a silent room and this app is still useless. Current phone, current version- it just doesn't work.

App has trouble reading low frequencies on a harpsichord. I tried contacting the developer but the email bounced. Are they still functioning? I use the app on an iPhone to tune a harpsichord, starting in the middle of the keyboard. Once I get to about F2 the app either reads an octave too high (says F3) or cannot give any frequency. Any solutions?

Good, but latest version has problems. Calibration by sound feature removed. This is very important to how I use it. Also pitch selection is extremely laggy on iPhone 12. This app is a classic, but doesn’t seem really supported anymore.

Serious loss of functionality with this update. Please restore full functionality to the signal generator function! Why did full frequency range disappear in this version? I use that every day to dial in reference frequencies. It was great, now its worthless. And the half second lag on the on off button for pitch generator is so annoying!!! Giving one star as of this update v2.2. will return to a great rating when I can generayr any frequency again.

Update?. This was my go to tuner for years. I recently updated my iOS and had to update the app. Please tell me how an update can turn a simple tuner that worked flawlessly for me for years into a useless pile a garbage. What happened? The needle display used to move smooth. Now it jumps and jerks. Why on earth would you change this is beyond me. Looking for another tuner I guess. Please change it back. I really used to love this tuner. I make my living as a studio guitarist in Nashville and use this every day for my acoustic instruments. Frustrating.

App no longer works with trumpet low range. I have use this app for quite a few years. It was especially helpful for practicing pedal tones. However it no longer responds to anything played below a B natural just under the staff. Uninstalling and reinstalling the program has not helped. I really like the layout of the program and the transposition feature but now I have to find something else. 🤔

Improve a app for support a new device. Why you don't update a app for support a new device !! It not work better than old~ i think this app is not support a 64 bit device ~ please make update this app Thank you.

Works ok. Seems to work OK, but the pitch pipe functionality is a little unintuitive. Once I looked it up on the support website I got it working, but found that part of my problem was trying to tune to very low octaves (tuba player). The pitch is inaudible starting around C-D3. I don’t know that that is a functionality of the tuner as much as it is of the phone.

Great Tool Does What It Says on the Tin. Cleartune works great (I'm currently using a 5S) for tuning my acoustic guitars. I couldn't be happier with it. When it comes to tuners, I mostly just want a tool that does its job and then gets out of the way. At this, Cleartune succeeds and also manages to look beautiful along the way. It's a great tool that I use all the time.

You don’t know what you have until it’s gone. I’m so freaking sad that this app no longer works after updating to iOS 11. I’ve literally been using this app for over four years and it’s been one of the best tools in my pocket.

Great/but buggy. This is a great app but is fairly buggy on the S6. It used to show the hertz and now it doesn't. When you try to turn on the frequency to bring it back and save the settings it doesn't stick. Kind of the main reason I downloaded this (tuning Lute). Considering how much it costs it needs to be updated on a more regular basis.

Tunes flat..... I have had this app for several releases and phones, and have been happy with it until lately. I upgraded my iPhone to a 5S, and now it seems to tune my Tuba about 10 cents flat. I thought maybe it was me, so I tried it with some friends, and with the band I play in, and it still registers flat. Would be nice if the app could play back a pitch that was reported to be in tune.....

My best tuner until…. Using iPhone 12 mini… I am not able to get it to listen to any note below Bb3. As a violinist, it was nice to be able to check all of my notes. Not sure what happened, but it has not worked for a few months at least.

Finally updated!!. Didn’t really need a lot of updates...but I used this tuner regularly. Simple to use without a lot of fluff. I was really bummed when it wouldn’t work with iOS 11, but finally (after 4 years) they updated this simple, functional, accurate tuner! Thanks so so much!!!

Please update. I’m not holding my breath, because it looks like the last update was four years ago. But I will agree. This is the best tuning app I have ever used. Please update it. I’m not going to pass on iOS 11 for a tuning app, even though I have paid for it.

Great tuner needs some love from the dev. The was my first iPhone tuner and is still my favorite. No frills, just what you need. At some point however the mic level or something seems to have changed. I can’t tune my electric violin without needing to plug it in. Works great for ukulele. Also lately when manually selecting pitch using the pitch tone feature, the wheel responds very inconsistently to touch which makes it frustrating to pick a frequency. I hope they fix this. It really is a five star app otherwise.

Sliding tuning gone: much less useful. I'm a singer and have used this app for 7 years. I like the ability to adjust the temperament, change octaves, and use both the tuning and pitch modes. Like another reviewer noted, the sliding tuning scale is now gone, which sadly makes app useless my purpose, since I work with choirs and often need to work in the cracks between standard pitches. If you just need to tune a single, loud instrument, it'll probably work fine.

So glad this was updated.... I didn’t value Cleartune until I couldn’t use it for awhile. I tried several alternatives and I learned that some are better than others. Somehow I’m able to tune both more quickly and accurately.

Excellent purchase!. This may be the only tuner you ever need, and at a bargain price. I not only to my guitar but actually tuned my excellent Japanese made Yamaha piano with it on the Werkmeister scale. I just paid $100 for a professional tuner to tune it, but I didn't like it. So I returned it myself with this app and it sounds beautiful!

2.2 update missing a couple things?. Great tuner app as always. Most recent update 2.2 for iOS 11 seems to be missing 2 things (both of which are also missing from the two screenshots on the Apple App Store): 1) Padlock in center of note wheel is gone. Wheel diameter is larger thus the padlock seems to have been pushed down out of sight. 2) The “A4 Calibration” auto calibrate microphone icon no longer appears next to the 440 frequency field. Thus I cannot auto calibrate off of 440 (Can still type desired A4 freq but the auto cal mic was really slick). Is it possible these features were moved to a different part of the app? Nothing yet in the Support FAQ.
