Clockwise is a minimalist and easy-to-use status bar application that stays out of your way while triggering all sorts of useful actions and alerts.
Clockwise's core functionality resides on events and actions. For example, you can set an alarm clock so your mac wakes you up every day to your favorite tune - with a different wake time for weekends. Or you may want to open a website every week to check its latest contents. If you need to take pills for a week before lunch, want a picture of your room emailed to you every ten minutes, or simply want to think of the pizza when it is ready, Clockwise will remember and do it so you won't have to. You could even have Clockwise read a dictionnary out loud during your sleep, or tweet your mac's CPU temperature! Your imagination is the only limit.
