Spinner Meter - measure spinner time and speed

Spinner Meter is a tool for calculating rotation speed and time of any fidget spinner.

Speedometer mode: holding the spinner in your hand, put it near the phone microphone and spin it as fast as you can. Spinner Meter will calculate the RPM (rotations per minute). Use in a silent room!

Spinning time mode: place the spinner on the top center of your phone, just over the proximity sensor, and spin it. Spinner Meter will start a timer and automatically stop when the spinner stops rotating.
