Chronos

Chronos fills a gap in Windows Mobile operating systems by offering an unlimited number of highly customizable alarms. Alarms can be set to signal only on certain days of the week; alarms can be one-time or repetitive; alarms can notify you by playing sounds, and turning on/off vibration or blinking an LED. WMA, WAV, MP3 and OGG alarm files are supported and you can select custom sounds stored in memory or on the storage card. A sound can be played with ascending volume and in loops (as often as desired.) Vibration (with required hardware) can be set to work before or along with the sound. Pulsation is customizable too. 

There are an unlimited number of countdown timers. These timers are used to notify you when a certain amount of time elapses. Countdown timers can have two time periods. You can completely customize the sound and vibration notifications for the timer in the same way as for an alarm. The settings of each countdown timer can be saved as a template for future use. You can use a timer to fix intermediate results too. For example, when you run 5 laps, you can track the time of each lap. A skin-able clock with a screensaver and chime sound allows you to better control your time.
