Terms of Use
By using Reaction Time Testers you agree to these terms.
Free to use
Every test is free for personal, family, sports and classroom use. You do not need an account, and we will never ask you to pay for a test.
Fair play on leaderboards
Post only scores you made yourself. Do not use scripts, auto-clickers or edited requests. Results faster than humanly possible are rejected automatically, and we may remove suspicious scores or rude nicknames without notice.
Not a medical or driving test
Results are for fun and learning only. They do not diagnose any condition, measure fitness to drive or replace advice from a doctor. Screens, devices and input methods all add delay, so treat scores as a guide, not a lab measurement.
Fair use of the site
Please do not try to break, overload or scrape the site, or copy it as your own.
Copyright

No warranty
