Week Scheduler is a very useful software application that reminds you of the many appointments you might have during working days. 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.
