Bloc blocks your distracting apps so you can focus on what matters. Start a focus session and Bloc shields the apps you choose at the OS level. No willpower needed — the apps are simply unavailable until your session ends. Want to quit early? You'll have to earn it. Bloc's friction challenges make you shake your phone, type a commitment phrase, or scan your physical NFC tag before you can unlock. It's the barrier between you and your impulses. How it works: Pick the apps you want to block Set your focus duration (5 min to 4 hours) Tap to start — your apps are instantly shielded Stay focused or complete a friction challenge to end early Features: Real OS-level app blocking (not just a timer or reminder) Friction challenges: Shake, Type, Sing, or go Upside Down to unlock early NFC tag support: Pair a physical tag to start/stop sessions by tapping Scheduled sessions: Automate daily focus blocks (e.g., every weekday 9-5) Live Activity: See your remaining time on the Lock Screen and Dynamic Island Streak tracking: Build consistency with daily focus streaks Activity dashboard: Track your focus minutes, sessions, and weekly trends Beautiful dark-first design with multiple themes Bloc uses Apple's Screen Time APIs to block apps at the system level. You choose which apps to block — Bloc never monitors your usage or shares your data. Your focus is yours. Bloc just helps you protect it.
