Clean This Mess! is a minimalistic application to handle ToDo lists and daily tasks, loosely following the Getting Things Done principles. It is extremely simple, yet powerful and easy to use. Try it out at cleanthismess.appspot.com. You only need a Google account (like your gmail one) to access it, and you can create a new one if you don’t have it already. I created and released it in mid-April, and it already has more than 50 early adopters!
