ReflexStats is a free collection of short brain and reflex tests you can take in your browser — no account, no download, no waiting. Each test gives you a clear score in seconds and lets you compare runs over time, so you can see whether you are getting faster and sharper with practice.
What you can test
- Reaction Time — how fast you respond when the screen turns green.
- Sequence Memory — remember an ever-growing pattern.
- Number Memory — recall the longest number you can.
- Verbal Memory — keep track of words you have seen.
- Visual Memory — remember the squares that lit up.
- Aim Trainer — pop targets as fast as you can.
- Chimp Test — the working-memory challenge that beats most humans.
- Typing Test — measure your words-per-minute and accuracy.
How it works
Every test runs entirely on your device using your browser. Your best scores are saved locally with localStorage — they never leave your device and we never see them. There is nothing to install and nothing to sign up for.
Why we built it
Reflex and memory tests are genuinely fun, a little addictive, and easy to share with friends. We wanted a fast, clean, ad-supported home for them that works on phone and desktop alike. The site is free to use and supported by advertising.
Accuracy & fun, not diagnosis
ReflexStats is built for entertainment and self-comparison. Scores depend on your device, screen, input lag and how awake you are, so treat them as a fun benchmark rather than a clinical measurement. The tests are not a medical or psychological assessment.
