Reaction Time

Measure your reaction time to the nearest millisecond.

A novel hold-and-release system combined with trials is used.

* How to use *

To begin, press and hold your finger to the screen.

When the screen turns green, lift your finger up as fast as you can.

Complete a total of 5 trials to get a final average of your reaction time.

No lifting early! Lifting early causes your current run to be reset.
