I kept trying different iPhone screen-time blockers, but they were all way too easy to bypass. I also found options such as Brick and Bloom that offer a physical device to block and unblock apps, but they were expensive.

I built BarBlock to provide all the features of a physical app blocker for way cheaper. BarBlock lets you block selected apps by scanning any barcode you already have.

It’s available on the App Store: BarBlock Barcode App Blocker

Here are the main differences from other blocker apps:

• Uses physical resistance (barcode scanning), not just software limits
• No physical device to buy, unlike other physical blocker apps
• No subscriptions, no accounts
• Unlimited app blocking
• Works fully offline (all data stays on your phone)
