Tangentially, what I want in a note/todo app is that the first screen will be a list of categories, like "car" and "shower". Under "car" would be a note I made that says "bring new SD card for dash cam". I'd look in "car" before heading out to the car, and see that note and remember to bring the SD card out to it. I'd habitually check all of these before doing anything, so I didn't keep forgetting things I needed to…
OmniFocus Or really, most any Note/ToDo that has first class support for GTD aka Getting Things Done which leverages the notion of @contexts.
Thanks for pointing me at OmniFocus, it looks really cool. Unfortunately, I'm an Android/Windows guy, and I doubt the Web version is going to be good enough at contexts for it to be worth it for me... :(
EDIT: Might give this one a try: https://appfluence.com/productivity/priority-matrix-omnifocu...
