This app is a shot clock app for Texas Hold'em poker.

How to use the app is in 4 simple steps!
You can use it by following the steps below.

■How to use

② After setting the shot clock (1 second to 999 seconds) on the setting screen, press the OK button to return to the main screen.
③ Flick the screen on the main screen to start counting at the set shot clock time.
④ Flick the screen again to restart the count.

Since this is the first app I've created, I'm sure there are many improvements to be made, so I'd appreciate any comments you can give me.
