Name: Reaction Tester: Reflex Game
Rating: 4.3 (8 reviews)
Author: FikirLtd

Reaction Tester measures your reaction time in milliseconds. The screen waits, flashes green at a random moment, and you tap or press as fast as you can. It keeps your personal best and your last five attempts, so you can see whether your reflexes are actually getting quicker. Free, offline, no phone needed.

HOW IT WORKS
- Start a round and wait. The flash comes at a random point between 2 and 5 seconds, so you can never learn the timing.
- Tap the screen, or press Start, the instant it turns green.
- Your time appears in milliseconds, and a new personal best is saved straight away.
- Jump the gun and the round scores as "too early" instead — no getting a fast time by tapping ahead.

WHAT IT TRACKS
- Personal best, kept on the watch between runs
- Your last 5 attempts, most recent first, with their average
- Everything stays on the watch. No phone, no account, no internet, no ads.

CONTROLS
Tap the screen or press Start to begin, then again to react. Buttons and touchscreens both work, so button-only watches are fully supported. Back returns to the title screen. Hold Up (or the Menu button) on the title screen to reset your personal best.
