If you keep disabling app blockers, you're not the problem. The blocker is. Most focus apps are only a few taps away from being turned off. blocked. changes that by requiring a real-world action before blocked apps can be accessed again. Choose the method that works best for you. NFC Assign an NFC tag as your unlock key. Keep it across the room, in another building, or anywhere that creates enough friction to break the habit. QR Code Generate a QR code and scan it whenever you want to unlock. Simple and free. Location Leave a chosen location and your selected apps become unavailable. They stay blocked until you return. blocked. is designed around a simple idea: make distractions harder to reach. No complicated setup. No productivity gimmicks. No expensive subscriptions. Build consistency with streaks, scheduled blocking, and an unlock process that requires more than a tap on a screen. Features • Block distracting apps using Apple's Screen Time framework • Unlock with NFC tags (not supported on iPad) • Unlock with QR codes • Unlock based on location • Create recurring schedules • Track focus streaks • Emergency unblocks for when you really need them • Emergency unblocks refresh every 2 weeks • Export data as CSV • Support for light, dark, and system themes A blocker should be hard to bypass. That's the point.

On ads, in-app purchases and device support there is nothing between them.
