Reaction Time Test
The classic test. Wait for the screen to turn green, then click or tap as fast as you can.
Start test5 attempts ~1 minClick or tap
Visual Reaction Test
A target lights up in a dark field. React to the visual signal as quickly as possible.
Start test5 attempts ~1 minClick or tap
Aim Test
Hit 30 targets as fast as you can. Measures your mouse or touch aiming speed and accuracy.
Start test30 targets ~30 secClick or tap targets
F1 Reaction Test
Five red lights, then lights out. React like a Formula 1 driver at the start. No jump starts.
Start test5 attempts ~45 secClick, tap or Space
Audio Reaction Test
No visual cue. Respond the instant you hear a short beep. Auditory reactions are usually faster.
Start test5 attempts ~1 minClick, tap or Space
Spacebar Reaction Test
Keyboard-only. Press the spacebar the moment the signal appears to measure key-press reaction time.
Start test5 attempts ~1 minSpacebar (or Enter)
Choice Reaction Test
Green means A, blue means L. Measures decision speed and accuracy, not just raw reflexes.
Start test10 attempts ~2 minA / L keys or buttons
Reflex Test
A target appears at a random time and place. Hit it as fast as you can. No clicking early.
Start test5 attempts ~1 minClick or tap the target
Reaction Speed Test
A rapid-fire sprint of 10 signals with short gaps. Tests speed and consistency under pressure.
Start test10 attempts ~45 secClick, tap or Space
Understanding the tests
Why take different tests?
Reaction time isn't one number. A simple reaction (one signal, one response) is the fastest kind. Add a decision and you get choice reaction time. Add an unpredictable location and you add search and movement time. Change the signal from light to sound and the timing changes again.
- Simple reaction
- Classic, visual, spacebar and speed tests: one signal, one response.
- Auditory reaction
- Audio test: the same task, but the signal is a sound.
- Choice reaction
- Choice test: identify the signal, then pick the right key.
- Reaction + aim
- Reflex test: find and hit a target that appears anywhere.

For beginners
Start with the classic reaction time test. It's simple, quick and a great baseline.
Start classic testFor gamers
Try the aim test for mouse aiming and the spacebar test for keyboard input.

The choice test adds a decision. Fast and accurate is harder than it sounds.

All guides- Reaction Time vs Response Time: What's the Difference?Reaction time is how long it takes to start responding to a signal. Response time is the whole thing: reaction time plus the movement that follows. Here's the difference, with examples from tests, driving and gaming.
- What Is the Fastest Human Reaction Time?There's no official world record for reaction time, but research and sprint starts show where the human limit is. Sprinters can sometimes react to the gun in under 100 ms, while most people average around 200 ms or more.
- F1 Driver Reaction Time: How Fast Do Drivers React at the Start?Formula 1 drivers launch their cars about 0.2 seconds after the start lights go out, on average. Here's what that number includes, how drivers train for the start, and how your own time compares.
