ReactionSpeed: Reflex Test
Test your reaction time
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Measure your reaction in five taps, track progress, find your tier, and compare with published statistics and friend goals.
ReactionSpeed measures your visual reaction time in five taps. Wait for the red screen to turn green, then tap as quickly as you can. Each signal appears randomly after 1–3 seconds with 1 ms precision.
Key Features
- Five-attempt average and best time
- Session history and line charts for progress
- Tiers, an RP gauge, and comparison with Human Benchmark statistics and cited public results
- Friend records and goals, plus source and video links
Premium unlocks full history and detailed analysis, the complete tier guide, and friend goals. Monthly and annual plans renew automatically until canceled; lifetime access is a one-time purchase. Localized prices appear in the app, and Restore Purchases is available.
Test and friend data stay on your device, and no account is required. Public-figure results are reference values, not a scientific or official esports ranking.
