ReflexLab grew out of a personal interest in improving reaction speed for gaming and sport. Training only sticks when you can measure it, so we built a tool that makes progress visible and repeatable.
Why ReflexLab Exists
Reaction time improves with practice, but only if you can measure it.
ReflexLab gives you:
- An accurate reaction time test
- Progress tracking: personal bests, averages, and trends
- A clean, focused experience
The point is to help you understand your own performance and improve it.
Built for Practice and Progress
One run tells you little. ReflexLab is built for the return visit, helping you:
- Test your reaction time regularly
- Track personal bests and averages
- Watch your scores trend down across sessions
We keep the interface simple so your focus stays on the test.
More Tools Over Time
ReflexLab now offers two tools: the reaction time test and the clicks per second (CPS) test.
We plan to add more, covering:
- Other aspects of speed and precision
- New ways to practice
- Deeper performance tracking
Each new tool will follow the same principle: useful and focused.
Free and Accessible
ReflexLab is:
- Free, with no accounts or sign-ups
- Fast on desktop and mobile
- Private: your results stay in your browser
Open the page, click, and you have your first result in seconds.
The Goal
ReflexLab has one goal: give you an honest measurement and a reason to come back and beat it.
If it makes you faster or more consistent, it's doing its job.

Take the reaction test, then measure your click speed with the CPS test.
