Concenturio

Concenturio is a curious application with which you can create reminders so you don't forget important tasks that you have to do.

Concenturio shows frequent reminders and notifications that tell you when the task should be finished, and invites you to get it done immediately.

You can create endless reminders for a multitude of different tasks, and assign different settings to each one of them. For instance, you can make it open pop-up windows at random times, or play a specific song at a specific time.

You can create a notification for grocery shopping and set it for every Monday at six, with a reminder half an hour before; and a notification to pay the phone bills once a month, always on the same day.

It works in the background and opens automatically at Windows' startup, so you won't have any problems using it.
