Just put your phone on the rotary table and leave the rest to the app. The app uses your phone's IMU sensor to perform calculations. Accuracy of results depends on your phones sensor resolution.

Usage areas:
- Calibrating motors.
- Control revolution values of record player, phonograph, gramophone
- Measure revolution per minute for any of rotaty device.

Features:
- Measure instant RPM value
- Calculate avarage RPM value
- Save results for motor calibration.

Important info:
* See maximum value on the screen.
* The average rpm value is reset by clicking an empty position.
* When the REC button is clicked, recording starts. Registration ends at the next click.
* RPM data and measurement time is saved as "RPM_data.csv".
* You can reach saved data from apps local files.

Ratings and reviews

I am a hobbyist software developer as well electronic hobbyist. Sensoring RPM with a camera is possible but it surely don't need to run with a game engine (Unity). Make a proper app with code base, it gives more control and more possibilities than doing it with Unity.

not working, provide guidance how to use

Measures RPM OF YOUR PHONE, which it seems to do just fine. I suppose this is useful for certain scenarios, but none of those scenarios are mine. Not being useful in my particular case is not this app's fault though, and it seems most reviewers here don't understand this concept.
