Spinometer Go! app for iPhone and iPad

Spinometer Go! measures the speed of two and three lobed fidget spinners and is a fun "frequency camera" for everything else. Spinometer Go! will automatically highlight the area where the spin is detected, even if there are multiple spinners in view!

Swipe left or right through the controls to choose the mode: 3 lobe, 2 lobe, and general frequency camera. When the spin rate is detected the image will sync up and the fidget spinner will appear frozen. Set display to RPM (rotations per minute) or RPS (rotations per second) and other options in the settings panel.

Spinometer Go! works best with recent iPhones with 240fps video capability, measuring frequencies up to 60hz. On older devices without high speed video support frequency detection will be limited. Keep steady and use good lighting for the best results.
