My phone is a graveyard of habit trackers i stopped using

Counted it up and I've downloaded 6 different habit apps this past year. currently using zero of them.
they all basically do the same thing check a box, watch a streak grow, get a notification when you miss a day. but something about each one makes me quit after two or three weeks. sometimes it feels too game-like, sometimes the notifications get annoying, sometimes i just forget it's on my phone.

what's the longest you've stuck with one and what made it different?
