GAMES TOOL
Reaction Time Test
Wait for the screen to change, then tap as quickly as you can. Tossora records your latest reaction time and keeps a short on-device session history.
HOW TO USE IT
Simple jobs, done fast.
Press start, wait until the stage turns green, then tap or click immediately. Clicking before the signal counts as a false start. Run several attempts because a single result can vary with attention, device, and input method.

PRACTICAL TIPS
- Use the same device and input method when comparing attempts.
- Run three to five trials and focus on the pattern rather than one score.
- This casual browser test is not a medical or diagnostic measurement.
How randomness works: Tossora uses the browser's Web Crypto API to generate random values on your device. That is stronger than Math.random(), but Tossora is still designed for everyday decisions, games, classrooms, and learning—not regulated drawings, gambling, or security-critical decisions.
QUICK ANSWERS
Reaction Time Test FAQ
What is a good reaction time?
Reaction time varies by person, device, attention, and test design. Use the score mainly to compare your own attempts under similar conditions.
Why did I get a false start?
You tapped before the green signal appeared. Restart and wait for the color change before responding.
