About Reaction Lab - Reflex Tests
Reaction Lab is a fast, accurate reaction-time testing suite built to help you measure and understand how quickly you respond in different situations. Whether you’re training for sports, improving focus, or tracking performance over time, Reaction Lab gives you clean, scientifically-inspired tests and easy-to-read analytics—right on your iPhone. Test Your Reaction Time in Multiple Ways Reaction time isn’t just one thing. Reaction Lab includes multiple test types designed to measure different pathways and skills: • Simple Visual Tap – Tap as soon as a visual stimulus appears • Choice Reaction – Respond to directional or on-screen prompts with speed and accuracy • Audio Reaction – React to sound cues for “eyes-off” testing • Haptic Reaction – React to vibration cues with no visuals or audio • Grip-Release (Inhibitory Control) – Hold, then release as fast as possible when prompted • Motion Reaction – React by moving the phone (tilt/lift/rotate) • Dual-Task Under Load – React while performing a secondary task to measure real-world performance • Fatigue Drift – Track how reaction time changes over a continuous timed session • Anticipation vs Reaction – Detect premature responses and impulse control patterns • Asymmetry Testing – Compare dominant vs non-dominant performance Track Progress Over Time Reaction Lab automatically saves your sessions and turns raw reaction data into meaningful insights: • Session summaries: median, average, best, worst, variability • Accuracy metrics: false starts, errors, timeouts • Trend charts by test type over 7 / 30 / 90 days • Per-session breakdowns across every trial Clean, Focused, Tool-Like Design Reaction Lab is built to be simple, fast, and distraction-free: • Large touch targets and high-contrast test screens • Clear trial progress indicators • Instant feedback on mistakes or false starts • Smooth navigation between tests, history, insights, and settings Fully On-Device and Private Your data stays on your device. • No accounts • No cloud sync required • No tracking • Works offline If you’ve ever wondered how your reaction time changes with training, fatigue, stress, or consistency—Reaction Lab gives you the tools to measure it.
