Have tried dozens over the years. Finally a list app that solves it. – Quire: Unfold Your Ideas Review

I can't believe how basic and powerful unlimited subtasks are, and yet how incapable developers have been around grasping this. (Shout out to Listmonger for trying before they vanished!) Thank you Quire for doing it right. This app is gorgeous. Oh, and it's not buggy, like others I've recently tried. Well done.
