Sub-millisecond Timing
Uses performance.now() for high-precision timing, measuring from the exact moment the screen turns green to your click, accounting for browser rendering latency. Want to check raw clicking speed too? Try our clicks speed tester.
False Start Detection
Clicking before the green signal is detected and the round is automatically voided. False starts are logged separately so you can see your anticipation rate. If you're curious how fast you can click overall, run a test cps to compare.
5-Round Averaging
Each test averages 5 rounds to give a statistically stable result. Outliers from nerves or distraction have less impact than a single-attempt test. Pair this with our test cps and aim trainer for a fuller picture of your speed and precision.
Touch Optimised
Works on mobile and tablet with touch events. Tap the zone when it turns green. Display latency on phones may add ~20–30ms to your results. You can also test your clicks speed on touchscreens the same way.
