How it works
The test listens for the relevant browser input, tracks elapsed time, and calculates session statistics in real time. Results can also be stored locally for guests, while signed-in users can save them to their dashboard.
How to use it
- Choose a mode or timer preset.
- Start the session and focus on smooth, controlled input.
- Review the summary card, compare your score, and repeat with a different pace.
Tips
- Play for technique, not only score spam.
- Keep the cursor path short and efficient.
- Use short breaks between attempts to stay sharp.
Common mistakes
- Starting too aggressively and fading early.
- Ignoring rhythm in favor of noisy movement.
- Comparing scores across different devices without context.

FAQ
Reflex Challenge questions
Is Reflex Challenge free to use?
Yes. Every core test on this project works directly in the browser without paywalls or forced sign-up.
Do I need an account to use this tool?
No. Guest mode works immediately. An account only adds optional server-side result history and dashboard widgets.
Why can scores vary between attempts?
Small changes in rhythm, device feel, browser load, posture, and warmup level can all affect a short performance test.
