Week Scheduler
Very useful to remind you of the lots of appointments you might have to keep during the working day on your computer. You can set 16 timers independently for each day of the week. When an alarm time has come, a blinking popup window comes up, with a message you can assign beforehand. Sound signal optional. Program window can be moved to the system tray, so it won't get in the way and it can be started iconized. If you leave your PC running overnight, the tab switches correctly to the next day.
