This free reaction time tester measures how quickly your reflexes fire. Click the box to arm a round, wait for it to turn green, then click again as fast as you can — your time appears in milliseconds. Click too early and the round resets. Play several rounds and the tool tracks your best and average times so you can benchmark your reflexes.
