I've found the best TODO 'app' is google calendar and a journal. I also have white board where raw idea get put down, but there id no real organization. once I decide I like the idea, task, ect I work it into my calendar and/or journal and go from there.

Same. Recurring and one-off scheduled tasks go on gcal (pay rent, go to dentist tuesday). one off things like grocery lists, notes, writing snippets go in a journal synced across devices (iA writer in a git repo).

I also use a Trello board for tracking longer term goals/personal projects.
