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.
