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.

A simple ad-free tool for measuring your reaction time.
