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.
