Four ways to test yourself
- 👁️ Visual — wait for the circle to turn green and tap.
- 🔊 Sound — no visual cue: react to the beep.
- 📳 Vibration — close your eyes and react to the buzz.
- 🎯 Choice — tap on green, but never on blue. Speed and self-control!
Test your reflexes in milliseconds: see, hear, feel or decide. Track progress.
