DoomStop
Read full descriptionHide full description
DoomStop is a free app that helps you break the doom-scrolling habit by making you physically earn access to distracting apps. Choose which apps to block, then set up your unlock method. Register an NFC tag and place it somewhere intentional — your gym bag, bookshelf, or desk at work. Tap it with your phone when you're back and ready. Or set a schedule to automatically lock and unlock apps at set times, no tag needed. How it works — Create a group of apps you want to block — Register an NFC tag or set a schedule — Lock the group when you want to focus — Tap your tag to unlock, or let your schedule do it Why DoomStop? Most screen time apps are easy to bypass. DoomStop uses a physical NFC tag as your key — a deliberate, real-world action that breaks the mindless reflex of picking up your phone. The friction is the feature. No account required. No data collected. Everything stays on your device.
