Reflex - Reaction Time Test

Train the fastest part of yourself.

Reflex is a reaction-time and reflex-training app built for the moment you want to know exactly how sharp you are — right now. Six modes test you in completely different ways. Together they make the most complete reflex workout on the App Store.

SIX REFLEX MODES

• Tap Reflex — The classic. Wait for green, then tap. Sub-200 ms is elite territory.
• Color Lock — A target color cycles among distractors. Tap only when yours appears. Trains attention as much as speed.
• Lights Out — Five red lights illuminate Formula 1 style. The moment they go dark, you launch. Jump the start and you're penalized.
• Sequence — A glowing pattern grows by one step each round. Repeat it back. One mistake ends the run.
• Aim Train — Twenty seconds of shrinking targets. Hit as many as you can before time runs out.
• Audio — Eyes closed. React when you hear the spoken cue. The hardest mode for most people.

GAMIFIED PROGRESS

Every run earns XP. Every personal best earns a bonus. As you level up, new modes unlock. Daily streaks compound. A growing badge collection tracks your milestones — your first sub-200 ms, your first 7-day streak, your hundredth run.

BUILT FOR FOCUS

• No accounts. No sign-ups. No nagging.
• No ads. No analytics. No tracking. Ever.
• No camera, microphone, or location access.
• Everything stays on your device. Works fully offline.

WHO IT'S FOR

Gamers chasing sharper reflexes. F1 fans curious about their launch time. Esports players warming up before a match. Anyone who wants a thirty-second cognitive workout between meetings. Friendly competitors who just want to beat their own best.

THE NUMBERS

The average human reaction time is around 250 ms. World-class athletes break 200 ms. Where do you sit? Run a few rounds and find out — your score updates the moment you tap.

Made with care. Designed to respect your time and your privacy.
