Most focus apps fail because quitting is just one lazy tap away. Threshold is an Android launcher that replaces your home screen with real exit friction. Pick a mode (Work, Study, Sleep, Meditate) and lock in. Choose your strictness level—up to a full launcher takeover with deliberate cooldown delays. Features built-in doom scroll protection to cut off short-form video feeds. 100% offline, zero data collection, no accounts, and no internet access required.
