BeepTimer is a countdown timer. The user controls it by tilting the whole device and by pushing the button.

The typical usage proceeds as follows:

  1. Start the program.
  2. Tilt the device to the left or to the right to change the time interval.
  3. Push button to start the countdown. A short while after the start the screen will go off. The green LED will blink shortly every second the contdown continues.
  4. You may cancel the countdown pushing the button shortly.
  5. After the countdown ran through, the device begins to blink intensely with the red LED and to beep (because of a bug in Circle OS it  is possible that there will be no sound). Push the button shortly to stop the signalling and to put the countdown into original state.
  6. At any point you may exit the program -- press the button and turn the device over at the same time.

The program is free for personal use; otherwise, feel free to contact the author through the forum (personal message is sufficient).
