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.

doesn't work. it doesn't matter how close or what direction I put the Galaxy s24, zero rpm from a 3/4 hp 120v motor on a bench.

Hi, Sorry for not having a great experience withTachometer - RPM measuring app. It is designed for phonographes or rotarty devices to measure rotational speed with phone sensors. It does not use camera, so it is not possible to measure the rotation speed remotely. In order for the app to make measurement, it must return with the rotating device.

failed to output a realistic rpm on a known imbalanced machine. the phone was resting against the machine in order to measure the vibrations produced.
