I'm unfortunately going to have to post this in a few places because I don't know where it's going to get the most exposure, but I'll start here because I have a Desire. I need an app to manage the various projects that I have going on. In some ways, you can think of it as a todo application which has subtasks, projects/groups, action lists, sorting via time till due/time taken/project/importance etc. If you have the time, check out this site where there guy goes through a number of options and criteria for a good GTD (getting things done) application. I've tested: OpenLoops Astrid Goals Todo For starters, Astrid cannot sort by tag/project and non have sub-tasks. I'm really hoping there is a project management app out there and someone can help me.
