A pure reaction time test: lock onto the countdown and hit stop at the exact moment to see how sharply your timing and hand speed line up.
The single-point fixed reaction time test keeps things simple, direct, and surprisingly addictive. There are no complicated rules on this page—your only job is to focus on one critical moment and press stop when you believe the time is just right. This type of reaction test is perfect as both a warm-up and a baseline. When you later switch to modes with more visual noise or uncertainty, you’ll clearly feel the difference in focus, time perception, and consistency. Whether you just want a light, casual reaction test or a serious push for a new personal best, this mode gives you the core of reaction time testing without any distractions.
