About Reaction Time Tester
Reaction Time Tester is a dead-simple reflex game: watch the screen, wait for
it to turn green, and tap as fast as you can. Your reaction time is measured
in milliseconds and compared against your personal best.
FEATURES
- Basic Mode — pure reflex testing, tap the instant the screen turns green
- Decoy Mode — watch out for orange decoy flashes; only the real green
signal counts, tapping a decoy costs you the round
- Personal best, running average, and a history of your recent attempts,
tracked separately for each mode
- False-start detection — tap too early and you'll know it
- No account, no sign-up, no internet connection required to play
- Clean, distraction-free dark interface
