This tool lets you effectively manage your entire to-do list without problems.
Its interface is simple, and shows all your existing alerts in a list to the left. To the right it shows a small calendar.
GigAlarm stands out for letting you schedule a wide range of events in detail. You can set reminders for specific days, hours, minutes, or even seconds. You can also schedule an automatic alarm for several days of the week.
At the same time as the alert, the app can also be programmed to do a specific action: run a file, play a sound, reset the device, or just hibernate or shut it down.
You can select these options while using the software installer.
Shareware version with a 30-day trial period.
