Tap Duel: Reaction Time Test

How fast are you really? Beat today's Daily Challenge, then prove you're faster than your friends in 1v1 duels — online or on one device.

Tap the instant it turns green. See your reaction time to the millisecond — and how you rank against players worldwide.

Then settle it: challenge a friend to beat your time, duel 1v1 online through Game Center, or go head-to-head on one screen.

REFLEX MODE The classic reaction test. One tap, a global percentile, and a personal best to defend. Tap too early and the round is gone.

DAILY CHALLENGE A new goal every day, from speed runs to precision streaks. Beat it before midnight — your streak is on the line.

ONLINE 1V1 Real-time duels against friends or the world through Game Center. First to react wins the round.

LOCAL DUEL Two players, one device. Press and hold your half of the screen — first to release on green takes the point. Let go early and the point goes to your opponent.

CHALLENGE MODE Ten targets, random positions, a shrinking window. Accuracy counts as much as speed.

FRENZY 35 seconds. As many targets as you can hit. Good luck.

TRACK EVERYTHING Best and average reaction times, win streaks, daily streaks, and per-mode stats — stored on your device, no account needed.
