Measure rotational speed using your phone's camera or a simulated strobe light. Simply mark the rotating object and adjust the settings until it appears stationary to get an accurate RPM reading. The app also functions as a torchlight.
Measure the speed of any rotating object with precision using your phone's gyroscope or camera. View real-time RPM data on a live gauge and graph, save your measurements, and compare historical readings. Ideal for calibrating turntables and testing various rotating equipment.
This app uses slow-motion video to create a strobe light effect, allowing you to measure rotational speeds. It records video with detailed information like frame rate and exposure, and offers customizable text overlays.
