Is there a nice task/todo app/system for developers out there? [closed]

Question

I am looking for a really basic developer task/todo app or system. Are there any good ones out there? What are you using? All I need is a good overview and being able to add time and priority to my tasks.

Answer 1

I write tasks on an index card. When I'm done with the story, I tear it up. Very satisfying. Of course, this means only working towards one thing at a time, which is a great discipline anyway.

Answer 2

I just found what I was looking for. A really nice and simple todo app called Wunderlist. Thanks for all the answers though.
