Questions
The thirteen tests, explained simply
Which test should I start with?
The Classic Reaction Time Test. Every average you see quoted refers to this standard see-green-then-click benchmark, so it hands you a clean baseline. With one in hand, branch out: react by ear in the audio test, or put the same reflex under race-start pressure in the F1 test.
What do the five categories mean?
Pure Reaction is one signal and one response, the cleanest measure there is. Motorsport & Driving wraps that reflex inside race starts and braking hazards. Cognitive slips a decision in before you’re allowed to move. Sport & Skill borrows the way games use reactions — aiming, catching, swinging — while Endurance & Speed measures how fast you keep going rather than how fast you start.
Why am I slower on the choice and go/no-go tests?
They ask your brain to do more work. Picking the right target, or deciding whether to respond at all, piles real decision time on top of your raw reaction, which makes slower scores there entirely normal. Judge each test against its own score table rather than against the classic.
How are the tests scored?
Several rounds per test, scored on the median, so one lucky click or one distracted round never settles the result. The CPS test keeps the same shape: five click sprints, and the median round's clicks per second becomes your score.
Can I compare my scores across different tests?
Not directly, because every test asks something different of you, which naturally makes a good choice-test score slower than a good classic one. Tracking each test over time is the useful move: results are saved on your device, and the stats page lines your benchmarks up side by side.
Do I need an account or any equipment?
No. Every test runs in your browser, free of charge, with no sign-up, and your scores never leave your device. Not even the ruler drop test needs a ruler: it falls on screen under real gravity, and we turn your catch distance into milliseconds.
