In this the limited but therefore free version of Clinometer. It as all features but can not be calibrated. 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. 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 dont read the iTunes reviews every day.

With this tool, the slope can be measured by all edges of the device in every direction. When the device is put flat on the table a bubble view will fade in. The current features include:

◆ 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.

◆ Volume Button Lock: Use volume buttons to trigger the lock.

◆ 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.

Only the full version has a two way calibration feature!

Please support us and buy the full version if you can.

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.

Pros and cons of Bubble level and Clinometer app for iPhone and iPad

Bubble level and Clinometer app good for

Ive used this app for a number of years now. I use it to help me in my custom computer business to fit into tight spaces and tell me everything is level that needs to be. Very accurate super simple to use. Every phone I upgrade to, this is the first app I put back on.
Somehow or other this app got lost from my phone in the last system upgrade. I’d forgotten its name — just remembered that it had been terrific — and wasted hours looking for it under “level” or “bubble level”. Not finding it, and thinking it must have been discontinued, I even wasted money on a couple of other possible replacements, neither of which was up to the standard I’d been used to. It was sheer dumb luck that I stumbled onto it again as “Clinometer” but it was a relief when I did. It was worth wasting a few bucks on the others (now trashed) to see exactly how much better this one is.
I use the app to help level out our Small Winnebago RV. It seems to work very well for this. still trying other uses.
this is amazing application, help me many time in work. I recomend in 100 %
I used this application for aligning the telescope tripod, working excellent. Thanks.
In the latest update, if you enable the speech synthesis the application closes. Please correct. В последнем обновлении, если включить голос, приложение вылетает. Исправьте пожалуйста.
