Added repeat on the increment and decrement buttons. Every 120 ms you will get a new count if you hold the button down. You should still reliably get just 1 increment if you press and release.
Initial release. Count up to 4 numbers. App remembers the last state. Switch between 1, 10, 100, and 1000 increment / decrement options. Hold the select button when modifying a number to 0 it out. Short long short vibration and icon on a bluetooth disconnect.
