I wrote a toy app when learning iOS that took the items in a todo list and showed you two at a time. You’d swipe the less important one off the screen. It built a hierarchy and you’d end up with the “most important” item to focus on. It remembered previous choices (or you could start over) to make finding the next item quickly, with just a few more choices. It connected with the Reminders app and the Wunderlist API. I wonder if I could revive it with more services…
