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.
