Puac is an alarm clock program, which sits in the system tray and lets you sound as many alarms as you like. Options include periodical alarms, snoozing, sounding alarms which went off while the program was inactive, showing an alarm message, speaking a message, telling the time, opening files, programs, urls and playing sounds (e.g. mp3). Alarms are contained in groups which can be saved to disk. Possibility to synchronize with Outlook tasks and appointments. Alarms can be set to sound during a specific period, weekdays or any other Datum/time combination. Color coding of the alarms provide a clear overview. A plug-in system allows easy extension of the program by creating custom action, import, export and synchronization plug-ins.
