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, impulse control and more. Take a reaction time test, beat your personal best, and follow your times 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. Measures how fast and how often you catch it. TRACK EVERY RESULT - Personal best for every mode, with a trend chart of your times - An estimated percentile — roughly where your score sits against typical human reaction times - Consistency and accuracy scores, not just your fastest single attempt - Round-by-round breakdown of every test - Separate history and personal best for each of the eight tests - 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 reaction time, tap speed and memory span, with a trend chart that shows how your times move. 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.
