Clinometer + bubble level

Clinometer + bubble level application logo

This professional tool called Clinometer is the most precise (all you can get with some calculations) slope measurement tool for the iPhone, iPod Touch and iPad using all sides of the device plus the camera. It can be used for simple applications like aligning a frame as well as for more sophisticated fields of applications where an arbitrary slope needs to be measured exactly. Read the reviews (and write your own) for all the applications you find! Thank for all your positive feedback! Please use our support link if you have questions and suggestions, we don't read the iTunes reviews every day!

With this tool, the slope can be measured by all edges of the device and through the camera. The current features include:

◆ 3 Modes (incl. auto switching): Clinometer mode (auto when holding upright), Camera mode (any direction, manual activation) and Bubble level (smoothly fading in when holding flat).

◆ Relative angles: Besides measuring absolute angles, for every mode you can measure the relative angle between device positions

◆ Advanced two way calibration on all sides: For every 4 sides plus the bubble mode you can calibrate in two steps, which allows you to calibrate exactly even on non-level surfaces. Each direction can be calibrated individually to achieve the optimal precision.

◆ Speech synthesis: The device will speak the current reading, so you don't have to watch the display while measuring/aligning your object.

◆ Five different unit modes: The device can display the slope in degrees (rounded or in tenth of degrees), percentage, rise over run (common for roof slope measurement in :12) and 1V:H (common in engineering)

◆ Dial Rotation: You can smoothly rotate the background dial and thus define which side of the device represents 0° and 90° degrees.

◆ Motion-sensitive Lock feature: Besides the common instant simple tap hold mechanism you can activate the motion-sensitive lock. If activated the device waits for the final lock until you hold your device steady enough for at least 2 seconds. You can set the lock sensitivity between 0.1° and 1.0° degrees.

◆ Peer Mode: Use two devices to measure angles: One as a display, the other as the measurement device that can be attached to the hardware you want to align.

◆ Fullscreen Mode: The full screen mode can be toggled by tapping the center of the screen and by the upper and lower arrows in the center. This prevents you from erroneous inputs while measuring.

◆ Different color schemes: Press the S/C Button to instantly switch the color. The color can be selected differently for the bubble and the clinometer mode. The predefined color sets include day and night color schemes (Black on White, White on Black and Red).

◆ Adjustable Auto-Lock: You can prevent the device from turning into the sleep mode.

According to wikipedia: An inclinometer or clinometer is an instrument for measuring angles of slope (or tilt), elevation or inclination of an object with respect to gravity. It is also known as a tilt meter, tilt indicator, slope alert, slope gauge, gradient meter, gradiometer, level gauge, level meter, declinometer, and pitch & roll indicator.

For recreational use only. After the calibration it CAN (!) be very accurate especially for the main axis after calibration. The measurement is performed as well as possible (we try our best) by using the three inbuilt accelerometers.


We will improve the application long-term. This was the first application of this kind shortly after the opening of the App Store. Since then it is continuously updated and enriched with new features.

Was indispensable...😔  El R0BBO  5 star

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.

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


Awesome awesome !  Johnshares  5 star

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.


Best Clinometer  BakdaPfundt  5 star

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

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.

Excellent app - Great work!  Groovy Possum  5 star

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

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


Handy tool  Ptpowell  5 star

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


Great App  JusNoeAtty  5 star

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

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


Great update  1949cj3a  5 star

I always use this app and this last update makes it even better.


Amazingly accurate  xrayguy01  5 star

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.

clinometer -level and slope finder  marc erasmus  5 star

i have downloaded the updated version a couple of days ago and can only say an even bigger THANKYOU to the guys who developed this app. they have made the software even more responsive, it is now incredibly accurate!!! this is a killer app, well done guys, you have made my life a little bit easier!!! with this app, my iphone is my primary source of level for all our cnc machine setups. It is now jan 2014 and I just had to update my review of this app...FANTASTIC app, use it all the the view through camera for large scale machine so grateful for this app...thanks guys:)
