ReflexTap Reaction Trainer

Wait for the green flash, then tap as fast as you can. See your median, percentiles, and grade. Three modes, fully offline, no account.

ReflexTap is a fast, honest test of how quickly you react.

Wait for the screen to flash green, then tap as fast as you can. ReflexTap measures the gap between the cue and your tap to the millisecond and scores the round. Tap before the flash and it is a false start — no cheating the clock. A handful of rounds gives you a median, your best, your 90th-percentile consistency, and a grade from Slow to Elite.

It is a game and a training tool — for gamers, drivers, athletes, musicians, or anyone who likes chasing a number down.

THREE MODES • Quick Test — five rounds for a fast read on your reaction time. • Endurance — twenty rounds back to back. Anyone can be fast once; this rewards staying fast. Your 90th-percentile time is the score that matters. • Anticipation — no countdown, no on-screen instructions. Watch the dial and tap the instant it flips green.

WHAT YOU GET • Millisecond timing from a high-resolution monotonic clock — not wall-clock time. • Median, mean, best, and 90th-percentile breakdowns per session and across your recent history. • A daily best and a seven-day trend, on a Home Screen widget and a Lock Screen Live Activity while you test. • An Apple Watch app for a quick round on your wrist.

PRIVATE BY DESIGN No account. No cloud. No analytics. No third-party SDKs. Every score stays on your device. There is no network traffic of any kind.

ReflexTap is a reaction-time game, not a measurement or wellness tool.

A few taps. A sharper number.
