ScreenFine
Locks iPhone apps at your limit and makes you do pushups or walk to unlock them again.
ScreenFine sets a daily limit per app and enforces it through Apple's Family Controls at the OS level, so there's no "ignore for 15 minutes" button — the app just shuts. Getting back in costs 25 camera-verified pushups, 1,000 steps, mindful minutes, or a logged Apple Watch workout, never money: the subscription is a flat $1/week, and going over your limit is never billed to your card. An AI "villain," picked from four personas, narrates every time you hit the wall.

What holds up
- +Enforced by Apple Family Controls at the OS level — no "ignore for 15 minutes" button to tap away
- +Going over your limit costs pushups or steps, never money — the card is only touched for $1/week
- +Unlock requires a camera-verified pushup count or logged steps, not just an honor-system tap
Mind the limits
- −iOS only, and specifically needs Apple's Family Controls — no Android version
- −Unlocking depends on physical effort like pushups or steps, which doesn't work if you're injured or immobile
