anxiety
Anxiety is a super-lightweight To-do list application for Mac OS X Leopard that synchronizes with iCal and Mail. Its aim is to provide a streamlined, easily accessible interface to add and check off your tasks, while remaining poised to melt into the background at a moments notice.

Don’t let the name get you all kooky. It’s an “anxiety reliever” or “anxiety attacker.” It shouldn’t GIVE you anxiety! I knew you were wondering.
