BarBlock: Barcode App Blocker

BarBlock reduces screen time by adding real-world friction to app blocking. Instead of relying on willpower or screentime limits, you lock selected apps by scanning a barcode you already have, such as one on a book, food package, etc. Those apps remain blocked until you scan the same barcode again, creating a deliberate pause before you can open distracting apps. That brief interruption helps break automatic habits and makes phone use a conscious choice. Setup is simple. Choose the apps you want to block, scan any barcode, and the apps stay locked until you rescan it. There are no extra devices to carry and nothing new to buy. BarBlock focuses on a minimal, privacy-first design. There are no subscriptions, no in-app purchases, no accounts, and no sign-ups. You can block an unlimited number of apps, the app works fully offline, and all data is stored locally on your device. Nothing is tracked, collected, or sent to external servers. This is designed for people who want to reduce screen time, users who bypass traditional app blockers, and anyone looking for a simple, reliable focus tool without tracking or complexity.
