Flare Blink overview

Flare Blink is a reaction speed test game that challenges you to tap the screen the moment it lights up with a vibrant color. Every round measures exactly how fast your fingers respond, tracking your progress over time so you can see yourself improve. The game is straightforward: wait for the flash, tap as fast as you can, and record your reaction time. No complicated rules, no tutorials needed. Round after round, you try to outdo your previous performance and push your personal best lower and lower. All results are stored locally on your device. There are no accounts, no sign-ups, and no internet connection required. Your data stays with you. The app includes multiple visual themes — choose from light and dark options to match your preference or the lighting around you. Font size can be adjusted for comfort, and you can set which tab opens by default when you launch the app. Flare Blink is completely free with no in-app purchases or locked content.
