How fast is your reaction? Test it with the simple RXN Timer!

The user interface for this reaction test is simple, which focuses on three buttons: "Start", "Stop", and "Reset". To initiate a game, tap the "Start" button and the color indicator will change to yellow. As soon as the color changes to green, tap "Stop" as fast as you can! The reaction time will be measured based on how fast you tap the "Stop" button.

The timing of the color indicator is random, which will weed out the true fastest reaction time among you and your friends. Share your score to Twitter and show off your accomplishments.

Who will be the fastest?
