About Reaction Speed Test
Reaction Speed Test is a free browser-based platform for measuring and improving your cognitive performance. Whether you're a competitive gamer looking to shave milliseconds off your reflex time, a typist aiming for 100 WPM, or just curious how your brain compares to the global average — every tool runs directly in your browser with no download, no account, and no cost.
Our tests use the browser's performance.now()
API for sub-millisecond timing accuracy. All scores are stored only on your device — we never collect personal data.
The average human reaction time is 200–250 ms. Pro esports players typically score under 180 ms.
