Test your reaction speed.

Wondering your reaction speed?

When your eyes see something, your brain needs to first figure out what's happening then you can take action.

With this App, you can measure how long it takes for you to react.

- Compare your reaction time with the world and your friends and your family.
- Prepare yourself for upcoming challenges (game, meeting your boss or your friend/girlfriend, whatever)

How to play :
- Press START button.
- Tap screen when it turns red.

New stuff:
- Add Beats (kind of metronome), which can be used in any occasion where beats are required, such as I use it for push-ups and practice drumming
- Add ASCII Table (for developers)
