Reaction Time Trainer & Test
8 belt ranks, Game Center leaderboards, and a Daily Challenge that's identical for every player worldwide. How fast are your reflexes? Find out in 30 seconds.
How fast are your reflexes? Tap to find out.
ReflexDojo is a reaction time trainer disguised as an arcade game. Targets appear and shrink - tap before they vanish. Every tap is measured in milliseconds, every session is scored, and every score pushes you toward your next belt.
WHAT YOU ACTUALLY DO
Circles appear at random positions and start shrinking. Tap fast and clean. Miss, and it counts against you. Chain hits for combos. Ten targets later you get your average reaction time, your fastest single tap, your accuracy, and your best combo.
THREE WAYS TO TRAIN
Quick Play - A fast 10-target session. Perfect for a 30-second reflex check.
Training Mode - Pick your shrink speed: SLOW, MEDIUM, or FAST. Slow builds accuracy. Fast breaks your ceiling.
Daily Challenge - One new challenge every day, generated from the date itself, so every player in the world gets the exact same test. Themed runs like PRECISION GAUNTLET, SPEED DEMON, ZERO MARGIN and TITAN MODE, each with its own target count, shrink speed, miss limit, and 1-5 star difficulty. Come back tomorrow for a completely different one.
EARN YOUR BELT
Eight ranks, and the only thing that promotes you is your average reaction time:
White Belt - where everyone starts
Yellow Belt - under 700ms
Orange Belt - under 600ms
Green Belt - under 500ms
Blue Belt - under 420ms
Brown Belt - under 350ms
Black Belt - under 280ms
Master - under 220ms
No grinding, no coins, no shortcuts. Get faster or stay where you are.
COMPETE ON GAME CENTER
Five global leaderboards - Quick Play average, Quick Play best single tap, Training average, Daily Challenge score, and longest streak. Plus 21 achievements to unlock, from your first yellow belt to the hidden ones you'll have to find yourself. Compare with friends or chase the global top.
SEE YOUR PROGRESS
ReflexDojo tracks every session so you can see whether you're actually improving:
- Reaction trend over time, session by session
- Tap distribution - how many fast, average, and slow taps you land
- Time-of-day analysis that tells you the hours your reflexes peak
- Personal bests, accuracy history, and daily streaks
Most people find out they're 40-60ms faster at certain times of day. Now you'll know yours.
BUILD YOUR STREAK
Play daily to keep your streak alive. Streaks feed their own leaderboard and their own achievements - miss a day and you start over.
MAKE IT YOURS
Accent colors, circle themes, tap trail effects like Comet, Slipstream, Ember and Glitch, and four tap sounds - a subtle UI click, a bubble pop, an arcade blip, or a mechanical key thock. Or turn sound off entirely and train in silence.
WHO THIS IS FOR
Gamers sharpening aim and reaction speed for FPS and esports. Athletes and drivers working on response time. Anyone who wants a genuinely measurable brain and reflex workout instead of another idle tapper. And anyone who just wants to prove they're faster than their friends.
