Stroboscope app for measuring rotating vibrating oscillating or reciprocating objects.
It is most commonly used for:
- adjusting speed of rotation - for example adjusting speed of rotation of turntable
- adjusting frequency of vibration

How to use:
1. Start app
2. Set frequency of strobe light (in Hz) using number pickers
3. Press ON/OFF button to start the strobe light

- use button [x2] to double the frequency
- use button [1/2] to halve the frequency
- use button [50 Hz] to set frequency to 50 Hz. This is for turntable speed adjustment.
- use button [60 Hz] to set frequency to 60 Hz. This is also for turntable adjustment.
- activate duty cycle by checking [DUTY CYCLE] check box and adjust duty cycle in percentage. Duty cycle is the percentage of time per cycle when the flash light is on.
- optionally you can calibrate the app by starting calibration from MENU - Calibrate. It is good to do calibration when frequency is changed. You can also set correction time manually in Settings.


Accuracy of the app depends on latency of your device flash light.
