Not sure if it helps, but here's my workflow: - Google Calendar for maintaining appointments; - A notepad (the paper version, yes) for quick notes, I use it to really "picture" the things I think/talk about; - A whiteboard as a to do list, and for when the notepad is too small; As you can see, I use no apps at all. This is because I try to separate maintaining my workflow from the workflow itself, if you can follow me.
