How fast is your reaction time? RTap is a reaction time test and reflex trainer with 10 mini games. Test your reflexes, see your reaction time in milliseconds, practice every day and compete with players around the world on global leaderboards.
REACTION TIME TEST
Tap the moment you see or hear the signal and get your reaction time in milliseconds. Start with the classic reaction time tests for a visual signal, a sound and a race start, then try the harder reflex tests: pick the right color, avoid the traps, find the emoji and catch what falls. Every test shows how your reaction time compares with players around the world.
REFLEX TRAINING
Reflex games that call for quick decisions, focus and hand-eye coordination reward practice the most. In these games your scores and consistency usually improve more than your raw reaction time, so play a few rounds a day and test your reflexes again.

QUESTIONS AND ANSWERS
What is a good reaction time?
Most people react to a visual signal in about 200–300 ms. Under 200 ms is very fast. Reaction time to a sound is usually a bit quicker than to light.
Can you improve your reaction time?
Yes, to a point. Raw reaction time improves a little with practice, mostly in the first few sessions. Consistency and reactions that involve a decision, like picking the right color or ignoring a trap, improve more. Good sleep and staying focused help too.
How does the reaction time test work?
RTap measures the time between the signal appearing on screen (or the sound playing) and your tap, and shows it in milliseconds. Your phone's screen and touch sensor add a small delay of their own, so results can vary between devices.
Who is RTap for?
Anyone who wants to test their reflexes: gamers, athletes, students, or anyone who simply wants to know how fast they are.
Take the reaction time test, play the reflex games with a friend and see how fast you really are.
