Reflexo — Reaction Time Test

How fast are you, really? Reflexo is a fast, no-nonsense reflex game that measures your reaction time down to the millisecond. The screen changes colour, you tap — the gap between the two is your score.

SIX MODES
• CLASSIC — One round, pure reflex. Chase your lowest time.
• STREAK — Five rounds in a row; your average counts. A test of consistency.
• SURVIVAL — The reaction window narrows every round. How far can you go?
• TIME ATTACK — How many correct taps can you land in 30 seconds?
• COLOR HUNT — Don't tap every colour, only the right one. One impulsive tap ends the run.
• COLOR MATCH — Hit the button matching the colour that appears. Reflex plus decision speed.

WHY REFLEXO
• Millisecond precision — See exactly how long every single round took.
• Instant feedback — Each score maps to a rating, from NOVICE all the way to REFLEX GOD.
• Personal bests — Every mode keeps its own record, stored on your device.
• Works offline — No connection needed, no account to create.
• 10 languages — English, Turkish, German, Spanish, French, Russian, Arabic, Hindi, Japanese, Chinese.
• Accessibility — Colour-blind mode (symbols added to colours), configurable signal colour, reduce-motion option.
• Dark and light themes — True-black dark theme for AMOLED screens.
• Sound and vibration can each be turned off.

LEARN IT IN 30 SECONDS
Pick a mode, hit START, wait for the signal and tap the instant the colour appears. Tap too early and the round is void — patience is part of reflex.

So how fast are your reflexes? The only way to find out is to measure them.
