Free browser-based tests that measure reaction time, click speed, hearing, memory and other abilities, then rank your score against a population distribution
BenchSelf publishes 19 free browser-based tests that measure reaction time, click speed, hearing, memory and other abilities. Each test runs in your browser with no sign up required and no accounts to create.
After you complete a test, BenchSelf places your score in a percentile ranking specific to your device type, so you can see exactly where you stand relative to others. The site stores your scores in your own browser for your history and export, and stores one anonymous row per test attempt to build the population distribution.
The site emphasizes that it measures only what a browser can measure, noting the limitations of consumer hardware. There is no advertising, no affiliate links, and nothing to buy. The results database is not for sale and no third-party scripts are loaded.

On a mouse, anything under 200 milliseconds is genuinely fast and puts you in roughly the top quarter. Most first-time results land between 220 and 260 milliseconds. Under 150 milliseconds is rare enough that it usually means the trial was anticipated rather than reacted to.
Touchscreens add real latency because the screen has to detect the touch, debounce it, and report it, which is slower than a mouse switch closing a circuit. A 40 millisecond gap between the two is normal, which is why touch results are ranked only against other touch results.
You can improve your measured result substantially in the first few sessions, but most of that gain is learning the task rather than getting faster. Genuine improvement past that point is small and slow, and the fastest way to improve your number is to fix sleep and remove distractions.
Your scores are kept in your own browser so you can see your history and export it. BenchSelf stores one anonymous row per attempt to build the population distribution containing the score, device category, and a random token, with no account, IP address, or way to identify you.
The physiological floor for a visual stimulus is around 100 to 120 milliseconds, and reaching it requires knowing exactly when the stimulus is coming. Under real test conditions, sprint starters are ruled to have false-started below 100 milliseconds because reacting that fast is considered impossible.
