About this app

The Inclinometer is a very simple yet accurate slope measurement tool that offers a dual, analog and digital, display of the data acquired from the mobile device's sensors. To measure the inclination of a surface or plane, all you have to do is to align your phone or tablet along with the surface. If the device is in a perfectly horizontal position, our app will normally indicate zero (0.0°) for the roll and pitch about the X and respective Y-axis. With one decimal place, the measurement's accuracy is one-tenth of a degree (0.1°). If the readings for a horizontal surface are not zero, they can be automatically adjusted by using a straightforward Calibration procedure. Moreover, our app includes a large, easy-to-use compass with optional black or white dials that shows the true north direction and the corresponding numerical values for azimuth and declination. A tap anywhere on the dials will show an extra menu that allows you, among other things, to save the current values of the measured angles.

Key features

- text-to-speech option (set your speech engine to English)
- pause buttons for roll and pitch, and also compass dials
- alerts with sounds and vibrations
- special software optimization to lower the power consumption
- option to show the sign of the angles
- simple commands and ergonomic interface
- large, high-contrast numbers and indicators
- no intrusive ads, no interruptions
- white and black dials for both tools

Initially I'd given one star, even thought the app is a very good tool to use with a star tracker (astrophotography) due to its reliance on Internet connection. By purchasing the app (dirt-cheap) the issue is resolved and I'm able to give it the proper rating.

Thank you. Internet access is needed to display a small ad that helps keep the app free. If you prefer an ad‑free experience, tap Remove ads in Settings to upgrade to 'Inclinometer Pro'. Microsys Team.

Be nice to be able to buy it just to get rid of annoying ads, otherwise it works well.

Didn't work at all. It might because It asked for my location at installation and I said "Only this time." But in any case, it didn't have any function. I don't like apps working in the background, only I'd I am using it. It didn't allow that, and didn't allow me to change the settings to go back and try another level of permission, so uninstalled it.

Our app does not need Location permission; if enabled, location is read once and only used to compute Declination, to offer you an accurate compass. Moreover, Inclinometer does not work in background! That being said, we thank you for the feedback provided and we are looking forward for your updated comment and rating. Microsys Team
