A simple or infuriatingly impossible game?!
Tap the start button to begin and then simply tap the stop button after the specified number of seconds have passed. The difficult part? You have to count the seconds in your head. Or out loud!
Level 1 is 1 second, 2 is 2 seconds, and so on. You might be surprised how good (or bad!!) you are.
Your high score is kept in sync between the iPhone and Watch apps.
