Usible, accurate and attractive. It just works!. This app is easy to use and once calibrated (very easy to do) is very accurate. The layout is logical and UI is attractively styled. Easily the best Clinometer and/or leveling app out there. Way to go! Feature request: - Red colored skin to preserve night vision - Lock feature so you can place the phone in a tough to see place to take a measurment, press a button to lock it, and then bring it back to where you can read it to see the reading.

Great app just wish it had better Bluetooth features. This app works awesome for a smooth surface like a roof or sidewalk.. But when I build trails I use a clinometer that I can tell the average grade over a distance.. When I saw this app advertised as being able to use bluetooth I figured when I connect 2 devices together it will tell me the average incline between the 2, however it only allows you to see the incline of the first device on the second.. Pretty much I need this app to work like a real clinometer and give me the average grade of a surface between 2 points.. But for a dollar it's an awesome app.

Breitling great for not $7500. Love this app, used it for everything imaginable for many years. Nice that it was developed by the guy who invented Breitling chronometers!

Best iPhone app I've downloaded yet.... No bugs, crashes or lags - does what it says it will with accuracy. Love the update with the bubble level (probably most useful on 1G or Touch, though since they have flat backs). Gorgeous, clean visuals. A perfect demonstration app and very useful tool for MANY people. Wouldn't it be nice if they were all like Clinometer? Fewer tip calculators and girlfriend dialers, more Clinometer type apps please...

Yep!. Oldie but goodie! This app is a must-have tool.

Waste of $1.99. Instructions basically say “This is self explanatory.” Paid $1.99, tried figuring out how to get a slope for about 10 minutes, gave up and deleted it.

Solar panel tilt angle. Using my iPhone 11, I can set the appropriate incline angle of the solar panels on my RV’s roof, no matter where I’m located and even if the RV is not perfectly level. Voice output is an added bonus. Use the base of the phone for angle from horizontal and the side edge for angle from vertical. Well worth the money.

One of my favorite apps. Excellent and used often. This is worth 99 cents, especially since it actually calibrates correctly, unlike the free iHandy level, which doesn't. (the free Stanley level also calibrates correctly but is very simple). Anyone who knows how to calibrate a level knows you have to do it on a surface twice, each time 180 degrees apart which this does correctly. I paid $40 for an actual inclinometer and this does the job just as well if not better. It also upgraded to an HD version on my IPad, which works even better since it has a longer edge. Works flawlessly. Great app!.

No Tutorial. Warning: There is no tutorial nor instructions on how to use this app beyond calibrating it.

Great app!. If you want to read, go ahead, but for those of you who don't: It's worth it, it works, so go download it! I downloaded this app a few weeks ago, thinking I might possibly use it someday. My bf and I are remodeling a house. Currently, we're tiling the bathroom shower with ceramic tile. The ceiling has a few weird angles and slopes, so the further up we get, the more we're having to cut the tile at these odd angles. The slope we worked on today was at the top and we were having trouble getting the right measurements. That's where this app came in... I whipped out my iPhone, held it up against the ceiling to get the slope, held the phone up to the tile to get the same slope, and actually used my phone to draw the line (although I don't recommend the latter :-). My bf cut it and it fit perfectly!! I never really thought I'd use my phone for something like that, but now that we know it works, we're coming up with all sorts of uses for it. Big thanks to the creator!

Excellent. This app does everything they claim and does it very well. I work with inclines, gentle slopes and fall lines. What I need is an inclinometer that has that nice beautiful red arrow precisely pointing down the fall line. Trying to guess the fall line of gentle slopes by trying to interpolate the direction indicated by an offset bubble is too imprecise to be of any real use. If this app could be made so as to enable the choice of having the fall line clinometer arrow indicating the slope even on very gentle slopes, that would provide greatly increased utility.

On the level, every time!. This beats any leveling device for your RV hands down. Just place your cell phone on a semi level surface of your RV after opening up the app, turn up the volume and let the automatic or manual leveling jacks down and a voice will inform you when your RV is level to a great degree of accuracy. No more so so bubble levels and guessing the degree. You will know to a decimal point what is just right. Compare this to what is in your RV now and you, like I, will use this app religiously from now on. Thanks for a great app product.

NYC Master Rigger. I assemble Tower Cranes, set Large Mobile Hydraulic Cranes and survey high rise construction sites for cranes. My work needs to be "on the level". As a secondary piece of equipment, I carry my IPad2 everywhere with me and am able to make preliminary measurements with the Clinometer application, that so far have been verified accurate by the findings of a professional survey team. it is amazing that something so simple to operate can be so useful. My team of iron workers up on scaffolds can't believe that the steel they used to dangerously fit to fit into place now lines right up when they receive it by crane because I level each piece with the Clinometer before the crane lifts it. Nice product. It has my full endorsement! NYC Master Rigger 184 DOC

Complete your Swiss Army Phone. I was installing a new dishwasher and needed a short bubble level. I only had a long level - too long for the job - and I didn't want to go to the hardware store and spend $10 for something I wouldn't use often. "hmmm. I wonder if there's an app for that?" Clinometer performed admirably. It has since saved me other trips either to the garage or hardware store. It's accurate, readily at hand, inexpensive, and, like any good tool, works without complication or fuss. Thanks for your good workmanship on top of a good platform.

I keep finding uses for this outstanding app. This is a beautiful, accurate and surprisingly useful application. I use it for all sorts of things from simple level checks to angle measurements in my workshop. My favorite use is obtaining altitude readings for my telescopes. Last week I helped a DirecTV installer who came by to check our site (and who forgot his own clinometer) to locate the position of one of their southern satellites. I'm now a geek legend to my kids!

Exceptionally sensitive and accurate. This is a great app to have around. A buddy bumps into picture on the wall. You can level it. Is your surround sound system's calibration mic flush and level before you calibrate? be sure of it. The best part is, the iPad can check the level of some areas a full-sized level just can't get in to. The calibration feature is a must and I'm happy to see it. The bubble level and inclinometer makes this app so generally useful, I'm using it for something new every day. If you're handy...and slightly OCD :) ...this app is pretty much for you.

Best Yet!!. Absolutely incredible! I was sold on this just after reading the reviews alone! Let me tell you, I am not a contractor but after I bought this I found it very useful for leveling things around the house like the washer, dryer, fridge and whatever else that may need to be eventually leveled. I love the toggle feature between the black/white. Oh, and also the bubble that comes into effect when you lay your iPhone flat, HOW COOL IS THAT!!! Just like a real level!! WORTH EVERY PENNY!!!!!!!

I use it every day - incredibly useful for so many things!. Have this on a 1st gen and 3G and both are very accurate (two good phones). The 1st gen was a little off so I calibrated it at work in the lab and retested several days later by putting it on my telescope. Was dead on! A RED light skin would be great for night vision around telescopes. Can't wait for the bubble level feature. Can we get a green laser line out of it too?;) Great job! ***** Update: The features of the latest version are great! Thank you for listening to everyone's suggestions. This app has turned given new life a low tech DOB telescope.

Bad for golfers. Not accurate enough at 1-4% slopes. iPhones with protruding cameras need cases with flat backs.

Basic and user friendly. I purchased Clinometer because it can show the angle in large back numerals that are easy to read in daylight. I also have TiltMeter Pro which has extra advanced features but does not offer a display that works as well in daylight. I like having both, at least until TiltMeter Pro offers a better outdoor display. Daylight display is important to long range shooters needing to determine uphill and downhill angles. Not all construction takes place inside. Therefore there's a lot of places that Clinometer's better display is preferable. If TiltMeter Pro wasn't out there with extra features I would have given Clinometer 5 stars.

Simply fantastic!. I have had this app for quite A while now, and have probably used it in the shop at least once a day, primarily as an angle finder. Once calibrated corectly, it is VERY accurate, rivaling some of my more expensive units, and all for a $buck$ To the last guy who gave it one star, RTFM! this app does all it claims. It did crash once I installed the update however after reinstalling all is perfect once again. Also this has been updated very frequently, so if one were to have a problem I'm sure it would be short lived. Having used it so often over the past few months, I would certainly miss it if it were gone. If your looking for a good clinometer, you found it!

Great app and support. I’ve had this app on all my phones since I guess it came out. I know it’s been quite along time. What is interesting is apps come and go but this app has always received updates. I have great respect for developers that keep apps like this working.

Waaaaaay too complicated. This thing is way too complicated to calibrate and to read. The read out is absolutely stupid. I do not recommend this at all.

Still a solid app in 2022. Absolutely perfect for a discerning engineer — well designed, clean, no bloat, reliable 0.1 degree increments and small install size.

Needs a better calibration system. Very hard to trust the readings without calibrating with a bubble level first.

Great tool!. This is amazingly accurate! I didn't know that it had a reading option for pitches (example: 4.5/12). I have been in roof truss manufacturing business for 22 years and always wanted to have a tool to measure slopes of existing roofs. This is it! So quick and simple and the lock feature works great! This also has a veriety of options such as the rotate feature which allows you to rotate the dial 90 degrees. I used the bubble feature and it works well! One thing, depending on the type of protective case you're using, you may have to pull the iPhone out to use it's straight edge for accurate reading. I bought a rubber protective case that has straight sides and a flat back so I don't have to pull the phone out to use it. Last thing, calibration is so simple! Good job guys! Five stars was a no brainer!

Great app. Like all the others said, great app. One suggestion though, and forgive me if it's already been mentioned in the hundred or so other reviews. It is useful to be able to determine the angle from your eye to some distant object by sighting along the edge or the face of the iPhone. Two new features would greatly simplify that. First, make the Lock button on the screen bigger. Second, have the app beep or make some kind of sound so you know if you've actually pressed the button. These would allow you to take sightings without looking at the screen.

Simple and works good.... Simple to use and calibrates well. It's calibration has you measure the same surface in opposite directions so that it can average the readings and decide where zero should be. This makes it possible to calibrate your phone--in a case--on a non-level surface. The only thing I might add, is the overall angle of a surface in the bubble level mode, instead of just the x and y components. This, of course, takes some vector math to get right (involving finding the normal vector to the surface given the two component vectors, and then using a.b=|a||b|cos(theta) to find the angle between the normal and z-hat, making it is something that I don't want to have to do by hand in the field.

It only gets better each time. I jumped on this one when it first released as I saw the utility immediately. Each release has finessed the original concept while never loosing the ease of use. This latest release with peer-to-peer ability really is cool. One of my uses of the clinometer app is in leveling my Airstream travel trailer when setting up and the ability to have one of my two iphones sitting on the floor or the trailer while I am outside adjusting the level of the rig is outstanding. I did have a little trouble at first figuring out how to get the two iphones connected (no documentation yet), I finally discovered that you have to wait for them both to see the other and then press connect on both iphones at the same time and then they both come up wanting to know whether to be the measuring or display unit. Once one of them is selected, the other immediately assumes the complimentary roll. BTW, this all works using the 3G network as I tested with both iphone set with WiFi turned off. Don't bother with other inclinometer apps, this is the ONE that does it all. dt

Grea app, the update is appreciated.. Very legible display. Good UI, I like the color options. And, it talks! Some time ago, I needed to set the edge of a 3D model at 30° relative to the monitor prior to 2D rendering for an isometric illustration. As the component was at a skewed angle, there was no way to instruct the program to do this. So using the app, I held my iPhone to the screen at 30° and rotated the camera view until the edge of the model was aligned with the edge of my iPhone. Viola, perfect 30° angle! Thanks again for a well designed, useful app.

Constant tweaking!. A really neat app, but frequent updates and tweaks seem unecessary for what amounts to a fairly simple application. I'm afraid it's going to get bloated to death. The new background is completely unnecessary - what was wrong with black or white? I feel like this is one of those apps that in the next few releases we'll start to see sound effects and a function for checking the weather. Please, keep it simple and accurate that is all.

Used to be awesome, now confusing. I used to absolutely love this app; it was beautiful and simple and intuitive. In recent releases it has gained many features at the expense of usability. I keep getting into modes I don't want like recalibration and the color keeps changing and I don't understand what all the tiny little unlabeled icons are for. I have had to delete and reinstall to get out of modes I don't understand and didn't want. I just wanted a level & bubble level and don't want to take the time to learn all these other features. Very frustrating.

Continued great work. I've had this since early versions. This app has been incredibly useful when I've needed to check level and now it's even better with the camera slope indicator. The updates have been excellent, and the UI continues to get better. Super easy to use but has the features needed. Excellent calibration routine. Smoothing and averaging and display locking makes this very friendly.

Good app...still needs a few features.. I am adding to my previous review ( see below) and adding one more star. The latest update added a lock feature. I really like the audible lock signal. Still needs the feature to measure heights (see previous review). 4 stars for now. -------------- (previous review) Works well. Would be nice to have a lock button to lock the measurement into the phone so you could move it and record it. Also, a handy feature would be to have an automatic calculation of approximate height of an object based upon distance to the object and angle observed. It's an easy calcuation, and would make it handy for the casual user who just wants to have fun with it. Well done, but I'll hold off on more stars until I see what the future holds. On a similar note, I did try to contact the developer via email a couple of weeks ago...still no response. Hmmm.

Amazing. Calibrating some mechanical stuff with. Works prefect. 👌🏼

after much reading and comparison shopping...this is it!. i was going back and forth deciding which application to purchase between Clinometer and Tilt meter, they both seem to do the same things, Clinometer seems to have more reviews and to me the graphics looked pretty good, and i loved the way how Clinometer is so easy to calibrate. I'm an architect, and i think this should be a pretty cool/ fun tool to have. =)

Great for iPad, Oldie that's Actually Maintained. The iPhone has the compass app which has a built in level. However, the iPad has no such built-in utility even though it's a great tool for doing such things. Thanks to this app it has one, and a darn good one at that. Kudos to the developer for continually updating the app. I've lost track of how many classic apps from the time period when this one was released that are no longer supported. Nice to be able to still use an oldie but goodie.

Outstanding. I have used this app since 2008, and it is fantastic. The current version is pure sweetness, and I cant wait to put the peer mode to work after I spring for the 3GS phone and have a pair to work with. I used the app to measure critical slopes in a large community wide access upgrade to meet current ADA codes, and it proved to be as accurate as seriously expensive engineering tools, and far more handy to use.

Most sensitive inclinometer out there. Wow is all I can say. Just finished laying out tubes for Outlaw Street car and using my lazer level and inclinometer to be certain I maintained square and angles for triangulation of all pieces, I decided to see what this app showed. After calibrating, I put it into decimal point readout, and found to my suprise it was within .01% of my lazer. This will give me a HUGE advantage over my competiion at the track. Kudos to the dev for making it, and thank to Apple for freeing me from the evil empire (you know what I mean)...Now I want a Mac Book Pro!!!

Perfect for golfers using Aimpoint Express. This app is perfect for golfers using Aimpoint Express to gauge the slope of greens. AE recommends a 9" Husky Digital level the costs around $60, but a larger iPhone (I use a 6+) with this app is just as good and far more portable. Love that you can read both axes (left/right and uphill:downhill) at once without moving phone. Since I always have my phone with me, I'm always ready to calibrate/double-check my feet read when on a practice green or during a practice round. Just make sure you have it set to display % slope, not degrees, for Aimpoint Express.

Great potential if a few enhancements are added. This app works great, but could it's applicability could be expanded to many new and very valuable uses in exercise physiology, physical therapy, and sports medicine with a few enhancements by the developer. The main change needed is to increase the maximum measured range of rotation from 90 degrees to 360 degrees. Then the app could be used efficiently and accurately as a Flexometer or as a Goniometer generally.

Nicely designed app. Very easy to use and get readings. Highly recommended.

Very accurate. I work in a surface mine where I build roads for giant mining trucks and other equipment. I use this app for quick reference while building ramps and such until I can get an official survey of my work. I am consistently accurate with the official survey when I use this app. Our surveyors use very expensive and highly accurate equipment to get their readings, I paid .99 cents for this app and as far as I can tell Its just as good.

YESSS!!!!!!. WOW! Incredibly wonderful inclinometer. Insane precision for a phone, the calibration feature is PERFECT, the auto bubble level when laid flat, (has its own separate calibration), is also insane! This APP is extremely useful, not just a toy! Oh, and it's an uber cool toy too. Thank you for such an wonderful app… Now if we can get a data logger for the accelerometers, especially one with this sort of precision and attention to detail… Not just Ghetto-Tech-Pro knock off.

Very well done. I got this app because it can calibrate on a non-level surface. That ability makes it so much more useful than alternatives that require a level reference surface. The displays are extremely clear. It seems to be accurate to less than 0.2 degrees, which is way better than I can get with conventional levels. Works great on my iPhone 4.

Inscrutable. Bought it. Ran it. It sat there saying 0.0 and wouldn't change no matter how I moved my iPhone. The "manual" is just equally inscrutable calibration instructions and says things like "press the button that automatically enables if you're holding the device correctly." No idea which button it means, but I sat here holding the phone level, plumb, etc and the calibrate button is always grayed out. There's an icon that goes between a locked padlock, unlocked padlock, and a bar with shaky lines. No idea what it means. No info in the "manual." Maybe this is an accurate clinometer but the UI and manual are so awful I won't ever know.

Cheers for the lock button!. As I wrote for the original version: Works very well and is intuitive to use. The accuracy I get on my iPhone is ±1 degree. Version 2.1 adds a very welcome "Lock" button to lock the dial for readout after taking a sighting. Minor quibble: The lock button label is the reverse to the way one would expect - the button is red/locked while the display is free, and green/unlocked while the display is locked. I understand the rationale to indicate the *action* of the button press, but since a lock button serves as *state indicator* in many GUI apps, it would be better to reverse the labels, so that the label indicates *state* rather than *action*.

Perfect!. I love this app. It’s perfect for setting angles while sharpening knives. Works flawlessly!

Great, Simple, and useful little application.. This is a great and simple and quite useful application for everyone. It could be improved for accuracy, especially when the phone is laid on its back... but I didn't expect scientific precision either out of a phone or music device. Love the display and its fast and adjusts quickly.. allows for calibration. One of my favorite apps thus far purely for the level of quality of the application.

Beautiful, Useful, and Accurate. I reach for this tool all the time. Leveling Monitors at work, setting up desks that need to be level, anythiing that I would have used a level for in the past (but rarely had one handy) I can do with Clinometer. The fact that you can calibrate Clinometer to measure accurate level, even on a non-level surface, is the key - take a measure, flip, take another measure, and Clinometer is accurately calibrated. An amazingly useful tool to have with you all the time. Well worth the investment!

Mr. Awesome in the field or workshop.

Great App. Great app, very simple interface and easy to use 👍🏼

Lovely. Nice app works well. Don't forget to cuddle your mum.

Mr. Hi there Great app very useful for quick and easy checking roof pitches etc Regards Adept

The perfect app. App works absolutely brilliantly. One big frustration though... why the need to choose degrees or percent in settings (which is quite a few taps/clicks) to change each time? Why not a major unit as it is currently and a minor unit below in smaller font for those of us who need both but don’t want to constantly be switching between both? User selectable primary and secondary units please? Indispensable app. Absolutely love it

JJL. Excellent App well worth the money

Feedback improvement. Very useful and well-designed. Would be even better if you could switch on the >>camera<< when using it so it can be like a real clinometer! i.e. view through the lens. The designers web site url has no conact info and the support url is the same.

Absolute Precision. Built with Absolute Precision! Love it. And they keep making it better (hopefully always keeping it clean, simple and precise). Go buy it, cool tool for the belt.

Crashes on start up. Why are so many apps crashing? The previous version of Clinometer was brilliant. I just downloaded this new version for my ipod touch and guess what... it's crashing on start up.

Great app. Does what it says and does it well.

Levelled. Brilliant. Better than my old hand held clinometer By about 50 times.

Clinometer. Very simple to use and accurate.

Mr. Great tool from very clever mind. Absolutely useful. Well done.

Handy tool. I build animated windows and this is a great quick tool to set inclines and levels fast thanks for building this

Highly polished app. I wish all apps were this perfect. Well done.

Best Clinometer. Has no glitches so far and has the most sensitive adjustment of all tested. Excellent for what we need it for.

Great!. But would like to see this also in DMS ;)

Not as good as previous. The early model was very good,on new model lock does not work,which i need for my work,cannot sight and calculate the reading when not locking to measure height of trees,slopes,stockpiles etc.As a suggestion Peter could you do an update to include the recorded camera picture and measurement from 2 angle shots as some other height/slope instruments do. If you could do this update you would have a real winner,I know you will do your best,and would be very happy to pay a bit more to have such a handy instrument in my pocket. Keep up the very good work.

Clino is Excellent. This is a first class app that I find very useful and accurate. I use it to help align my telescope when setting up for astro photography and that needs to be spot on, it does a first class job.

Designer. Great App. Works very well & is very accurate. Rise on run is a great way of measuring slopes, if like me, you under take design work for wheel chair access to buildings. Keep up the good work.

Clinometer. Just brilliant

Was indispensable...😔. Well, this is/was (!) one of those fabulous apps that always did exactly what it said , and just kept doing it. Super useful in the construction industry. Bought a new iPad Pro, and the app is all over the place and not working. Hey devs, what's up ? Would definitely PAY for this ! Just fix it and you'll get six stars.

Gorgeous. Great looking app & wrll thought out what more would you need from an inclinometer. Maybe toggle speech? So you could sight along the side and listen to the angle if you were maybe triangulating the height of a tree or checking the angle of the sun. oh and maybe a hold button too? But top marks so far for a spanking looking app and the calibrate function

Great app. I own 2 pinball machines and this app is great to make sure the tables are level across and have the right slope down.

The best so far.... It is one of the most accurate and well polished application of this type so far. I use it for jobs around the house and in the 4WD when I'm out in the bush.

Awesome awesome !. This is absolutely brilliant. It's so accurate and with the voice giving the exact reading I can now use it when I can't see the screen. Thanks to the team.

Mitch. Throw away your spirit level and you it when offloading the best tool is the one you always have on you

Excellent app - Great work!. Very useful device at work and at home. Heard it can be used for checking powder snow slopes for avalanche risk as well.

Tradie. I've been using this app for over a year now and find it to be very accurate. Well worth the money!

Excellent. Excellent, clever,helpful, nice interface

Great tool.. So accurate, I'm impressed!

Great App. Perfect for setting the "pitch" of Surfboat rowlocks and very easy to use.

Brilliant. Works well

Amateur doer. Very useful tool.

Great app. Great app, very handy, good value

Awesome !. This is so perfect ! Thank you ! This app made my front page of apps lol. It is that awesome. Within 30 minutes of getting it, I needed to use it. My level was to big to fit where I needed it. And who doesn't want a level in their pocket haha. Perfect ! ! Nice features.

Mj. Great app I love it

Very Helpful. We have moved several times while I have had this app. Great for hanging pictures!

Excellent. TEs

mhmmgm. its aight

Terrific App.. Useful for all kinds if things from leveling a table or hanging pictures to field work using trig to estimate the heights of buildings. Very well done.

Bien. Idéal pour pente d'excavation.

Absolutely accurate. I enjoy to use that on wind turbine job.

Tres utile. Surtout en aéromodélisme

Great app. Have only had for a short time but has worked fine when used. Should come in real handy.

Very Accurate. Very cool app. Tested it against a physical level and it was 100 times more accurate. Very cool app!

Real good looking and functional. Note 10

Fantastic!. As soon as I opened this app I thought it was absolutely unbelievable. This app has enormous potential.

Works well. Used it to level a kitchen cabinet and drawers. Also to set my table saw blade.

Good App. Use it for trig calculations.

Top notch !. Excellent

I like. I like

Good. Like iy

Great !. Does exactly what it is supposed to do

Great app but latest iPhone update made it all wonky.. We use this app at work every day and it’s been incredible for the last 4 years. However, since the last Apple iPhone update, the app goes all wonky when you tilt your phone sideways to use the long side of it as a level. It does it to my phone and all my coworkers as well. Would be great to get that fixed. The whole level circle just gets stuck in a corner when I turn my phone in landscape.

Works well enough. I use it at work often. Building block walls and MSE walls. Works in a pinch when a level isn't handy.

Niveau. Super bien fait !

It works very well!. This is a great app. It works very well!

Wow. Très précis, simple d'utilisation et change de mode automatiquement.

Great app. Very impressive app!

Clinometer. This is a perfect app. I'm so happy it was written and look forward to more.

Level app. Great little app. Very easy to use

Ultimate landscape photographers tool. This is not a bogus tool. I do interiors and architectural photography and good levels are hard to find. This one exceeded my expectations! Once you calibrated it (I used a hi quality bubble level) it's an incredible tool - and it's neatly tucked into my iPhone! SUPER USEFUL. THANKS GUYS!

Great. Word good

Great App!!. Use it often

Excellent App. 5+ 🌟 app. Use it for all my woodworking projects. The camera feature is so awesome.

Top level app with low price.... Great application! User interface is great. Love the fact that its a bubble level as well as a clinometer. I use it to track the path of the sun during location filming. When there isn't a "proper" clinometer around, this will sub in quite nicely. In addition, the developer seems to care about his work as there have been many updates posted. All this for only a buck.

Great app. Great app comes in handy when working

DJW. Nice app!

Clinometer. Works well

Wow!. This App is crazy useful!

Just perfect! Thank-you!. Use this for leveling a telescope mount. Wish: Red interface for night viewing!

Super. Très et très précis mais il faut prendre le temps de l'équilibrer après ces un charme

Good app. Does what I need it to do, and does it well. It's frozen on me once but shutting it down and restarting fixed it. Highly recommended app.

Fantastic App!. 4s Brilliantly simple and accurate! Use of camera a bonus, with a guide for eye level

Very cool.... Interface is fantastic, responsive, can be quite acurate and very fun. Level your paintins, your snooker table - or like me, just for fun...

Found on AppADay. I always write 1 star reviews until I have seen the app so as to not confuse others into thinking I paid for it and recommend the same. I will update if this app is worth keeping.

Ridiculous. Ridiculous how good this one is. Thanks

Level. Great app use it for TV dish setup

Works very well. I like it very much. Looks and works great.

Very functional. Great app.Use it all the time even in my machining setups:-)😄

Awesome!!. Great!

Great app!. I work in dynamic storage and use this app daily for setting slope on gravity conveyors!!

Handy app. I've only used this once so far, to dial in a satellite dish. But so far it has been invaluable.

Great tool!. This has got to be one of the best levelling/measuring applications out there. I work at an automaker (surviving) and have used this tool for presentation material due to it's accuracy and display. Also, building decks as a side job I find this app most useful for building stair runs and small levelling work. Can't do without it since I got it!

Awesome!. I was a little skeptical when I purchased this but after several months of use, it has yet to fail me even once! Remember, if your phone is in a protective case, you must remove it from the case to be accurate. I also recommend calibrating it before first use.

Really a great app. This is an amazing little app that utilizes the hardware in the iPhone and iPod Touch to measure angles of inclination. I use it with an iPod Touch 4 and it is amazingly sensitive to the angle and has a very nice clear read out. It's difficult to imagine how it could be improved. But I'm sure these guys will come up with something. The programmers for this app are very creative. Nice touches.

Nice app. I've calibrated and used this app a couple of times and it works smoothly, no gliches and is accurate. It would be even more useful if there were a percent slope scale in addition to the degree scale. Percent slope expresses the rise/run as a percentage. For example, a 45 degree angle is 100% slope, since there is 1 foot rise for each 1 foot run. Thanks, keep up the good work.

Level Anything Works Great. Ok, I looked around a bit, another review of another product mentioned Clinometer so I checked it out. This thing works every time all the time. I measured my doors, my floors, the slope of my roof, the slope of my stove angled top. I got out pictures of hiking trips and rock climbs and measured the angle of the climb. I'd say this is my favorite App right now, it just works like you want it too.

Better, Better, Best. This app just gets better with every upgrade. Been with this app since the first version almost a year ago and have been absolutely delighted with each improvement. Can't wait for the upcoming "major upgrade," although it will be hard to improve on this version.

Aircraft mechanic tool. I'm a student A&P mechanic, and today I got to use this to verify the correct aileron deflection angles on a Piper Comanchee to an accuracy of a tenth of a degree. It was very easy to zero out the neutral angle and then check the extremes. The cheapest digital incinometer I could find on a google search runs 70 USD. Compare that to this *superior* 99 cent program. WOW.

Does exactly what I wanted. This is just a perfect clinometer I wanted to have. Very slick design, quick and easy to use - does what it says on the tin. A pity that some people here are rating it badly here but it seems it's the author of the much worse competitor product. Blame on you!

Remote mode is fantastic. If you have a second iOS device, it can act as a remote display for the one doing the measuring. This is a very nice feature and is beautifully implemented via bluetooth. Very nicely done. -Woof!

Very Impressive. Great job by the developers! I love this app and love showing it off to everyone I know. Huge hit on the jobsite. One feature that would be nice is if you could switch to the bubble level with the phone on it's side instead of only on it's back. Either way this app is a must have. If you don't have it yet, start downloading it now.

Great program. I've been looking at buying a "digital protractor" type of level but they've been too expensive at around $60-$90. For less than a buck this program does an even better job than the dedicated unit. Helps justify the cost of that new toy!

Nice application.. Initially, the level was off a degree or two, but after I calibrated with a spirit level, it was right on. It will be interesting to see what the repeatability is down the road. I wouldn't use it for serious engineering work, but for 99 cents it is a great tool to have in your pocket!

Great Pocket Tool. This little has come to the rescue many times over the past 3 years. Whether it's leveling a new stove, washing machine or paving stones in the back yard. Everyone that's seen it in action has downloaded for themselves. If you've ever wished you had a level handy, you need this app.

Nice program. I bought both this and Tilt Meter Pro. Tilt Meter Pro requires a level surface for calibration. Clinometer just needs a surface that's reasonably level. Calibration is a two step process. You push the calibrate button, then rotate your iPhone or iTouch 180 degrees and push Calibrate again. Clinometer then compares the two readings to determine true level.

ExPalmNewton. Love this app. Just the other day I used it to estimate the height of a tree and I was way quicker than the guy holding a stick at arms length. It's also great for leveling a clock that hangs on the wall next to a door. It's always askew and I can fix it in a flash.

Drummer's best friend. Wanna set up your music gear the same way in the studio, on stage, and in the practice space? I've been using this since back when it really was free. It's still worth it, so if you plan to pay the two bucks for a clinometer or level, make sure it is this one.

Fantastic app. I bought this when it was initially released and have been extremely impressed by the quality of subsequent updates and the overall feature set. In my experience it has been very accurate, remarkably useful, and absolutely worth the money. Thank you to the developer for this amazing app.

Stopped working with iPhone OS 2.0.1. Nice app. Calibrated with accurate spirit level and tested out pretty accurate. Once I installed 2.0.1 it would no longer launch. HAVE SINCE UPGRADED TO 2.0.2 AND APP WORKS PERFECTLY. Screen just went blank and then returned to home screen. Seems to be very hard to contact Peter. NEW LINK WILL MAKE GETTING ANSWERS EASY. I rate 4 stars, the 2.0 version will meet several needs for field work. A slope percentage readout will be very useful.

the lock. Bought the early on and like it a lot. However, the new delay in the lock feature appears to have made the feature useless to me. It's so sensitive it's nearly impossible to hold it steady for any length of time. E-mailed Peter and never got a response.

Tool Rating. I gave this App 5 stars + because it was exactly what I was looking for. It's many tools in one and Its voice read-out was the clincher. It's incredibly accurate but if you have your phone in a case, remove it before you calibrate it. Many Thanks !

Project Manager. Great app. I use it on job sites to confirm sidewalks slope correctly. If I need to check a longer area I just use a straight metal stud and put the level on top of it. Much handier than hauling normal level. Also like the bubble level feature.

Wow.... Yup, thats all I can say. This App is way cooler, nicer, and much more functional then I could have imagined. This is not just some bubble level. It looks and feels like a mechanical device. Absolutely worth the money. Ive never given an app a 5 Star rating... but the clinometer has earned it.

Absolutely beautiful!. From an interface and graphic design perspective, this is one of the most beautiful apps on the Store. Elegant, simple, and precise. While it's a simple tool it really should be selling for at least $5, perhaps $10. It's exceptionally crafted and useful.

Perfect for ski slopes!. Although probably not developed for skiing, this app ROCKS! Easy, intuitive, and accurate! Does not tell you if the avalanche danger is high but if you're using this for slope angles you're already mountain wise enough to know that avi conditions occur at greater than 38 degrees.

Insanely Useful and Beautiful. This should be a model for all iPhone apps. Its aesthetics are clean and elegant. Anyone who needs to measure angles, whether navigators, carpenters or photographers can see the terrific utility of this app. It's also just fun to play with -- how steady is your hand -- can you hold your trusty iPhone within one half of a degree? Try it -- you can't go wrong with this.

A very useful app!. I'm up on scaffolding, and needing an angle measure for some garage ceiling work. I can go down to shop to get my inclinometer, but wait - there's one on my phone! Fired it up, got the angles that I needed and cut the wood as needed. This is a very useful app. You'll find lots of uses for it.

Works Like A Charm. Use this app all the time and it works flawlessly! It came in super-handy installing 8 sculpture columns at night on a deadline. Try reading any standard non-illuminated level in the dark and you'll be glad to have this! Nice graphics too.

Don't need this very often but when I do.... ... it is exceptionally convenient to have right there on my iPhone. I guess it's one of those things like a Swiss Army knife. You don't know how much you need it until you don't have it with you. Easy to use, accurate for most common uses, clean useful interface, does what it purports to do.

Excellent App. This app started out good and very clean. With updates it became even better and easier to calibrate and use. Very accurate and consistant. Even though it is an excellent app, the developers still keep updating it making it even better.

Eliminates Guesswork. It's handy because it not only functions as a simple level, but allows you perform fairly accurate angle measurement as well. Certainly as accurate as any ordinary level and with the benefit of always being in my pocket encourages me to check things instead of just accepting that they "look right".

Well made.. This is by far the best level app I've seen. It's accurate and best of all it seems like it takes a timed average of what the accelerometers measure and outputs the results to a nice dial that is very smooth. The bubble level is nicely done as well. Worth more than 99 cents.

Excellent app and great programmers. This app works flawlessly. I use it with my photography. Updates are frequent and the programmers really listen to user feedback. That is something that I don't always feel with other app program writers.

This App Rocks!. This app is easy to use along with being quite robust in it's features. Looks and works just as well on either the iPad or iPhone and I've even used the pairing feature. You can't go wrong with this bubble level and angle finder app.

Very accurate. I've yet to use this for anything professionally nor in the household but the acelerometer is extremely accurate, and this program takes advantage of it very well. The bubble level works upside down too. Very refined software.

Finding the break (slope) on the golf course green. If you have ever tried to putt on a slope you will know it is very hard to read the green let alone get the ball in the hole. well if you are trying to read the green this little App. will help get you there, even help you understand and read the break better. Good Golfing!

Awesome!. The title is all that really needs to be said about this app. You get the feeling you have a very expensive high-precision tool in your hands while using it. I am new to iPhone and new to apps but this thing is amagingly accurate, cool looking and fun to showoff and play with. I love it!

Simple. Works.. Does a decent job with great simple look. Love the 2.0 addition of the bubble that appears when setting it flat. I checked out the other similar apps and this one is by far the best. Can't go wrong for 99 pennies.

Building my kitchen. I'm in the middle of putting my kitchen together and have been using this to help scrib in the cabinets. It works well and seems very accurate. Also, the app has been updated several times since I've purchased it. Great support from the developer.

Great tool. I have used this for many tasks ranging from measuring slope inclination angles for backcountry snow studies to collecting experimental data for aerospace product testing and evaluation. The calibration feature allows this instrument to be calibrated to an NIST traceable standard, allowing me to use it as a legitimate measuring tool for data acquisition.

Amazingly accurate. I bought a digital clinometer before this app, big mistake, this app is just accurate if not more so. Perfect just as it is. Update:) After 4 iphones over the years this was my very first app purchase, its one of the very few apps I've used and kept and its still crazy awesome.

Camera assistant's friend!. I work as a camera assistant and I have found this app has replaced the digital inclinometer I once carried in my tool kit which I used to determine and later match camera position angles when doing scenes where visual effects will later be added. Very accurate, easy to recalibrate, and convenient. Having it on my phone keeps my tools close by! Love it and how well it works!

Hideous Icon =( -still ugly!!!!. The new clinometer icon does not say iPhone. I used to put it with all my other navigation and Geo icons, now I've hidden the new Frankenstein icon in a folder. I wish company's would just understand this one basic principle: Apple fans love apple for their design. The company's that do well in reproducing their own programs following the example of Apple are the ones Apple users are more likely to go for, it starts with the Icon, that's the first thing a 'app store browsing client' looks at, and that is how a company represents their first impression. And now you've ruined it.

Excellent tool!. I am an avid woodworker - who would have ever thought that for only $0.99 I could turn my iPhone into an incredibly accurate & simple digital angle finder! I use this app to align jigs, set saw blade angles and verify corner angles. It would be helpful for the tool to measure angles in the horizontal plane - as it is, you have to maneuver the workpiece to align with the iPhone's vertical plane, which is awkward.

Great App!. This is definitely worth 99 cents. It would be perfect if there was an option to prevent sleep mode. Also a button to lock the reading, otherwise this is amazing.

Great! Best App. Bought this app when it first came out and loved it - constant updates make this a great deal for the 99c (unlike like some other higher priced apps). If you own a washing machine and don't have a dead level basement floor you will use this.

Nice quality, Perfect, but. Everything is ok. It works nicely, as same as professional clinometer. However, it doesn't show anything but black blank screen when your iphone is running with iOS5 Beta7. It had worked until beta 6, hope it works again with iOS5 later.

Excellent with one question..... A terrific app but I feel that the rendering for the bubble level got worse with the third to last update - it looks kind of washed out now when it appeared much more vivid before. Can this be fixed? A sad blemish on an otherwise wonderful app.

Best level app among the fancy level apps!. Whether you actually need all the features or you just like the visual effects of this near-professional instrument, I suggest you pass on the basic ones and get this instead. Easily worth more than a buck!

Nicely done. Well done app... However, may I suggest a mode for measuring mountain slopes – particularly for assessing avalanche risk? Perhaps you could overlay the inclinometer over the live video from the camera and allow us to align the guides with the visible mountain slope and get a reading.

Not accurate enough. I was expecting the bubble level to be more accurate. After calibrating it and comparing it to my physical bubble level, it was not even close. For example; I have a 6' high book case, with the top of the unit leaning against the wall and bottom of the unit 1 3/4" out. The app said that it was level. The bubble in my actual bullseye level was only about half way inside the bullseye. The app seems to be off by approximately 2 degrees.

Very accurate for professional use.. I am a professional satellite installer and I found this app to be very useful and accurate. I used it everyday to install satellite dishes. I would pay $10 in a heart beat. By the way I got rid of my bulky angle finder which I used before on the job to find the elevation. Hitech device on a hitech phone. Wow A++++++
