Flasho: Tap Speed Test

Flasho is a reaction speed test built for anyone who wants to measure and improve how fast they can respond to a visual signal.

When you start a round, the screen will suddenly flash to a new color. Your job is simple: tap as fast as you can. The app records exactly how long it took from the flash to your tap, giving you an accurate reaction time in milliseconds.

Every result is saved locally on your device. You can review your history, watch your average reaction time improve over time, and try to beat your personal best. No sign-in required, no internet needed, no data ever leaves your device.

The app includes a history screen where you can track past sessions, see your fastest recorded tap, and monitor how consistent your reactions are. A stats overview gives you a clear picture of your progress without any clutter.

Settings let you adjust font size, choose how your history is sorted, and toggle haptic feedback if you prefer a physical response when the screen flashes.

Flasho is straightforward and distraction-free. No ads interrupting your flow, no purchases required. Just open the app, tap when it flashes, and see how fast you really are.
