Reflex Test

Ideal for gamers, athletes, and anyone wanting faster visual-motor responses. Great for improving reaction speed and hand-eye coordination.
Description
The Reflex Test measures visual-motor reaction speed and targeting accuracy through a sustained moving target task. It evaluates how consistently rapid motor responses are executed across a fixed duration as attentional and physical demands accumulate.
How It Works
Moving targets appear at random positions on screen. You click or tap each target as quickly as possible within 30 seconds. Each successful click records reaction time and spawns a new target. The session continues until the 30 second duration ends.
What Gets Measured
Average reaction time — mean interval between target appearance and successful click across all attempts.
Fastest and slowest reaction times — peak and floor performance within the session, reflecting response range.
Targets hit — total successful clicks within the duration, reflecting sustained output rate.
Fatigue pattern — reaction time change from the first half to the second half of the session, indicating whether performance is maintained or degrades under sustained demand.
Understanding Your Results
Consistent reaction times across the full 30 seconds suggests stable visual-motor performance under sustained demand. Increasing reaction times in the second half of the session reflects fatigue effects rather than a ceiling in underlying speed. Targets hit reflects combined speed and accuracy and is more sensitive to strategy — prioritizing speed over accuracy produces different profiles than prioritizing accuracy over speed.
Limitations
This test measures visual-motor reaction speed within a moving target clicking task specifically. Results are sensitive to input device type, cursor control familiarity, display refresh rate, and browser rendering latency, all of which introduce measurement variability in a browser-based format. Mouse-based and touchscreen-based results are not directly comparable. The 30 second duration captures short-term sustained performance and does not reflect reflex speed in naturalistic or high-stakes real-world contexts.
