How fast are your reflexes? RTap is a reaction time test and reflex trainer packed into 10 fun mini-games. Measure your reaction speed in milliseconds, train every day, watch your progress on graphs and compete with players around the world on the leaderboards. TEST YOUR REACTION TIME Tap the moment you see or hear the signal and get your reaction time in milliseconds. Start with classic tests for visual signals, sound and a race start, then take on harder challenges: pick the right color, avoid the traps, find the emoji and catch what falls. See how your results compare with other players. TRAIN YOUR REFLEXES AND FOCUS Games that call for quick decisions, focus and hand-eye coordination reward practice the most. Play a few rounds a day and watch your scores and consistency go up. 10 GAMES, 30 MODES • Simple Reaction – classic reaction time tests: race start, vision and audio • Color Chooser – tap the right color as fast as you can • Text and Color – a tricky color-word challenge for your brain • Don't Tap Red – react fast, but don't fall for the trap • Sliders – tap at the correct time, • Emoji Finder – spot the right emoji in a crowd • Swiping Games – swipe in the right direction • Falling – catch what falls before it hits the ground • Whack-a-Mole – the arcade classic, built for speed • Time Stop – stop the clock at exactly the right moment Many games come with several difficulty levels, so there is always a new record to chase. COMPETE ON 30 LEADERBOARDS Every mode has its own global leaderboard. See your rank, how many places you climbed and what percentage of players you beat. 63 ACHIEVEMENTS Unlock medals and trophies for hitting target times, mastering difficulty levels and staying consistent. TRACK YOUR PROGRESS WITH GRAPHS Detailed stats and charts show how your reaction speed improves day by day. 2 PLAYER DUELS Challenge a friend on the same device. Both react to the same signal: the faster one wins the round. 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. Reactions to sound are usually a bit quicker than reactions to light. Can you improve your reaction time? Yes, to a point. Raw reaction speed 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 much more. Good sleep and staying focused help too. How does RTap measure reaction time? It measures the time between the signal appearing on screen (or the sound playing) and your tap, and shows the result 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 faster reflexes: gamers, athletes, drivers, students, or anyone who simply wants to know how fast they are. Can I play with friends? Yes. Play a 2 player duel on one device, or compare your scores with friends on the leaderboards. Start training your reaction time now!
