This app functions as a simple Metronome for Windows Mobile devices. It was optimized for the square 240x240 screens so it should work well on all PPC devices without the need to scroll.

Features:

While the metronome is running, it will keep your device from suspending. If you like to have a visual indicator only, you can mute the sound. There is also an option to keep the backlight awake if you're primarily looking for a visual beat indicator.

To install, download the CAB and copy it onto your device, then run the cab file. You can uninstall through your add/remove programs interface.
