How fast are your reflexes? Find out in 30 seconds. Reflex is a reaction time test and brain training app with 8 ways to measure your speed — reaction time, tap speed, memory span, hand-eye coordination and more. Take a reaction time test, beat your personal best, and watch your reflexes sharpen week by week. 8 WAYS TO TEST YOURSELF Simple Reaction — Tap when the screen turns green. The classic reaction time test — pure visual reaction speed in milliseconds. Choice Reaction — Tap the matching direction. Measures decision speed, not just reaction speed. Go / No-Go — Tap green, resist red. A real impulse-control test. Audio Reaction — Tap when you hear the beep. Tests auditory reaction time, which is usually faster than visual. Sequence Memory — Repeat a growing pattern. Trains working memory. Tap Speed — Tap as fast as you can. A CPS test (clicks per second) for your fastest finger. Color Match — Same colour or different? Tests visual processing speed. Peripheral Vision — Spot the dot at the edge while looking at the centre. Maps your visual field. TRACK EVERY RESULT - Personal best for every mode, with a trend chart so you can see your reaction time improving - Percentile ranking — find out where your reflexes sit compared to everyone else - Consistency and accuracy scores, not just your fastest single attempt - Round-by-round breakdown of every test - Separate history for every skill — reaction time, tap speed, memory span and hand-eye coordination are tracked independently - Daily streaks to keep your brain training habit going - Shareable result cards to challenge a friend WHO IT IS FOR Esports players training reflexes. Athletes improving response time. Drivers curious about their reaction speed. Students of cognitive science. Anyone who has ever wondered how fast their brain really is. Reflex works as a daily brain training habit too: a couple of minutes a day on tap speed, memory span and hand-eye coordination is enough to see your reaction time trend downwards. YOUR DATA Every result is stored on your device — there is no account and no cloud sync. No sign-up, no email, no personal profile. Reflex is free and supported by ads, so it needs an internet connection to show them. Ads are never shown during a test, and you can watch one short video to hide them for 30 minutes. Ads are non-personalised: Reflex does not track you across apps or websites. Download Reflex and find out how fast you really are.
