Midnight Inbox
The original Mac GTD application, Midnight Inbox started it all way back in 2005. Inbox is still the only Mac GTD application to include more than just to-do lists and contexts. With Inbox collecting, processing, reviewing, and referencing are taken care of automatically for you. Work smarter, not harder, by organizing your projects, email messages, files, contexts and tasks so that you can always be on top of your world. It's available also for iPhone and iPad.
