Organize your life. Then go enjoy it.

What? A Todo list app to answer a notes question? Seriously, if you pay for the extras you can write notes in the comments field* and tag the whole note as well. It is on mac and iOS and you can share items to it from almost anywhere - share sheet in iOS and there is an “Add to Todoist” Service on macOS. *— I don’t know the maximum size of this field.
