Reminder Commander lets you configure all kinds of notifications (one-time or repeating). If you want, you can also set alarms to go off in Windows while you're using your computer.
Reminder Commander's interface displays the notifications as if they were tasks. For each of one, you can add notes, links, actions (run or open in your browser), sounds, or have them sent to your email to make sure you receive them, no matter where you are.
