Superb  Gsom111  5 star

Tuned my unplugged bass. If the room is quiet enough app correctly shows how detuned each string is. And free version is more than enough! A+


Handy  yuyyuuuyyy  5 star

Accurate, easy to use, and works on all my string instruments


Unsubscribe???  poorandbroke  2 star

I want to unsubscribe as it is too expansive for what u get


Didn’t realise how expensive it is  Xolo1974  1 star

I downloaded the wrong version and meant to download the limited version. But the cost is incredible and now I am signed up for 12 months. Good app but the price is ridiculous


Top app real cool  Nagunnoblu  5 star

Top app


This app tricked me into subscribing for $11.49 per week  Mysticspiralbamby  1 star

This app is a disgrace. Quickly clicking through the menu after opening the app for the first time in a while and I able to accidentally subscribe to an $11.49 per week subscription for something that was previously free. That is almost $600 per year. I am disgusted at this kind of dishonest behaviour and I hope this review serves as a warning to other users who are thinking about downloading this app. If you did accidentally subscribe, you will have 7 days to cancel before your credit card is charged.


Watch out  nogoodtuner  1 star

This app has an expensive monthly fee after a 1 month trial.


Not for violin!  KimoByrono  1 star

It says it’s for violin but doesn’t contain the option to choose violin to tune. Currently trying to work out how to unsubscribe before getting charged a rediculous fee of $12 per week!!!


Warning, not free, it will cost a lot.  Bobo2617  1 star

You cannot proceed with out committing to pay after the free trial. You have to remember to cancel or delete. A tad dodgy. OK if you are happy to pay.


Dodgy!  __Pat  1 star

Not very clear that I had subscribed to a premium version costing $12.49 per week. Avoid.

hangman o'leary

Excellent BUT far too expensive  hangman o'leary  3 star

Excellent app. Easy to use. Accurate tunings. Wide alternate tunings. Only drawback is the prohibitively expensive unlock price, which is literally 5X what it should be. I would have rated this app five stars if the price was reasonable. It is literally far cheaper to buy a hardware tuner than unlocking this app for a few months. Twelve months of subscription could buy a new guitar with a tuner onboard.


Not free. Unusable without sign up  Spectoral  1 star

Scammy app. Avoid. There are ten thousand free pitch tuners.


$7.99 per week🤨. Are you kidding me?  Jon.Galt.  1 star

Auto charges after free trial unless subscription cancelled. Try finding cancel option in the app. You won’t. Be careful with this one.

Awesome destroyer RQS

Terrible  Awesome destroyer RQS  1 star

So stupid, you can’t even use the app unless you wanna spend $8.00 so dumb. Don’t download.


Deleted  flaklein  1 star

No use unless you pay 8 dollars for it. There are plenty of free tuners in the store. Not worth it at all!


Add  Shawon17  2 star

I don’t like adds before starting


it’s a trap  EDK574  1 star

thought it was free. it’s not. actually VERY expensive


Huge scam..... do not recommend  guitarpunk101  1 star

This app is ridiculous, I tried canceling the subscription many times and I kept on getting billed for it weeks after I canceled it. Also, it says it’s free at first but really isn’t. DO NOT GET, I WARN YOU !!!!


Purchase the premium by mistake  pjvpete  1 star

I need somebody to write/call me back to cancel the subscription


The scam is still going for $7.99  jwjdufnri  1 star

A week. $7.99 a week for a guitar tuner.


SCAM  Newgfour  1 star

There is no free version of the app. You can download it for free but the moment you open the app you cannot do a single thing until you subscribe. Waste of my time.


DO NOT SUBSCRIBE!!  hpesojm  1 star

I bought this app a year ago for a reasonable $2.99. It did what it was supposed to do. Had no issues. All of a sudden I try to use this app and immediately it asks me to pay $7.99 for a weekly subscription. $7.99!!!!! I wish I could give this app 0 stars by the way they have treated other app purchasers and myself. Please read other 1 star reviews. I feel robbed


Free app with a subscription  Www1246742  1 star

Makes you sign up for a subscription within 2 minutes of starting the app, considering this is supposed to be a free app, this is a disgrace


Best tuner  Derekwalton  5 star

I have tested dozens, both free and purchased and this is the best that I have used.


Simple, effective  Emma79984  5 star

Really easy to use, great choice of different tunings


e String broke  Seanmurphy3828163747489194  1 star

This app I find is off key and it got me to tighten my e string until it snapped.


Excellent app  Hevynev  5 star

Does everything you need, I sing into the pitch checker feature when I'm trying to get the song in my head onto the fretboard! I really like this app :)


Bad tuner  Thomas445m22  1 star

Every time I try the ukulele tuner it says every string is string c and I now can't play my ukulele because it is out of tune completely

Fee Fontana

Good  Fee Fontana  5 star

Very Good!


Broke a guitar string using this app  TickleLittleGummyBears  1 star

It should say which way to move, broke a guitar string because of it


Nice app. Works well  Alan_2006  4 star

Good tuner with an understandable interface. Recommended. The tuning fork would be more useful if you could select by note rather than frequency.


Good interface  murney  4 star

Decent app, with good interface, among many SHITE ones. Thanks.
