D.off helps you break free from phone addiction without willpower. Set time limits per app group, and when you hit them, unlock by writing out a sentence — three on the free tier — or swap one for a 30-second exercise. That pause breaks the autopilot scroll. 70+ achievements, sleep lock (Premium), site blocking across six major browsers, and 7 languages. No ads. The sentence library ships inside the app, so unlocking works with no network.
