How fast are your reflexes? Test your reaction time in milliseconds. Reflex Test is a precision reaction timer with three focused mini games designed to measure speed, focus, and accuracy. Compare your results on global leaderboards and track real improvement over time. ---- GAMES ---- TAP ON GREEN - Classic Reaction Test Wait for the signal, then tap as fast as possible. A pure reaction time test that measures your reflex speed with no distractions. COLOUR & FOCUS - Brain Training Match the ink colour to the word. This mode challenges focus, attention, and cognitive reaction speed under pressure. SOUND CUE - Audio Reaction Test React to sound instead of visuals. This tests your fastest response pathway and improves sensory reaction timing. ---- REAL REACTION TIME (MS) ---- No vague scores. Your result is your actual reaction time in milliseconds - the standard used in sports, gaming, and neuroscience. Scores are averaged from your best attempts to reflect true performance. ---- GLOBAL LEADERBOARDS ---- See how your reaction speed ranks worldwide. Compete across three separate leaderboards and benchmark your reflexes against other players. ---- TRACK YOUR PROGRESS ---- Monitor every session. View your average reaction time, track improvements, and analyze your performance trends over time. ---- BENCHMARK YOUR RESULTS ---- Compare your score against global averages. Understand whether your reaction time is beginner, average, fast, or elite. ---- BUILT FOR PRECISION ---- Millisecond-accurate reaction timer Haptic and sound feedback Works in silent mode Light and dark mode Clean, distraction-free design Whether you're testing reflex speed, improving focus, or training reaction time for gaming or sports, this app gives you accurate, measurable results. How fast are you?
