Mosslock
iPhone app

Lock your phone. Grow your moss.

Mosslock pauses the apps that pull you away while you study, using Apple's Screen Time features. The time your apps stay locked becomes your study record, and every finished session plants a patch of moss.

What it does

Always yours to switch off

When a session ends, your apps open again. If a paused app still shows the moss screen, tap "Session ended — Unlock" or open Mosslock. You can also turn off Mosslock's Screen Time access in the Settings app, or delete the app, at any time. How to turn blocking off

Private by design

No account, no ads, no analytics. Mosslock never learns which apps you chose or how you use them, and your study records stay on your iPhone. Purchases are processed by Apple and managed by RevenueCat with an anonymous ID. Privacy Policy
