Plank hold
The visitor starts the hold with the phone on their back or in a pocket. The tool runs a clock and stops it when the motion sensor sees a drop. The time is the result.
Use the camera, microphone, motion or timer on this device. Frames stay here; the result is a number or a card.
This is a general-purpose tool, not medical, legal or financial advice. Figures are estimates from published food data or arithmetic. A qualified professional owns decisions that affect your health.
How to use it
Inputs are motion samples. Computation watches for a drop and stops the clock. Output is a hold time.
