Zonebox is a simple app for timeboxing - a little productivity trick.
Timeboxing means setting aside for example 15 minutes to write an email. By knowing there is a time limit, you'll be forced not to waste any time.
Zonebox helps you with everything - it will remember the task list, it will show you the progress as a little stripe on your screen and it will remind you when you're done.
