Focus Lab Blocker puts a moment of friction between you and the apps that pull at you — so opening them becomes a choice, not a reflex. Most blockers are just a wall with an "off" switch. Focus Lab Blocker is different: when you hit a blocked app, you have to earn your way in with a small ritual. By the time you're done, the urge has usually passed. CHOOSE YOUR FRICTION Every app gets its own unlock ritual: • Breathe — a few slow breaths before you go in • Cooldown — wait out a short timer • Intention — type why you need this app right now • Math — solve a few quick problems • Sweat — pushups, squats, or jumping jacks, counted live by the camera • Photo quest — go photograph grass, a book, the sink… something real • NFC tag — tap a physical tag you left in another room • Guardian PIN — a trusted person sets a PIN you don't know • Daily budget — a fixed number of opens, or minutes, per day A COMPANION THAT LIVES OFF YOUR WILLPOWER Adopt a pet that hatches from an egg and lives off your self-control. Every urge that hits a shield dings one of its meters — and every urge you resist earns the care item that heals it. No urges means a healthy pet and nothing to do: it never nags you into opening the app. But let its meters sit empty and it gets sick, and eventually leaves. BUILT TO RESPECT YOU • No account, no sign-up. • No ads. • Nothing leaves your phone. Photo and exercise checks run entirely on-device with Apple's Vision framework. No servers, because there's no network. Focus Lab Blocker uses Apple's Screen Time to enforce blocking, so it's as reliable as iOS itself. Reclaim the ten seconds before the scroll. That's usually all it takes.
