Lock - NFC App Blocker 앱 분석 (9월 23일)

Take back control of your attention. Lock is a focus tool that blocks distracting apps on your phone using a physical NFC tag. Tap the tag to lock, tap again to unlock. That's it. HOW IT WORKS 1. Choose the apps that distract you. Pick from a list of your installed apps, by category or search. 2. Tap your NFC tag to lock. Place your phone on the tag to activate blocking. 3. Apps are blocked. The selected apps become inaccessible until you unlock. 4. Tap the tag again to unlock. A new scan deactivates blocking. WHY LOCK IS DIFFERENT Most focus apps live on your screen, one tap away from being disabled. Lock lives off your screen, on a physical tag you have to reach for. A physical gesture, not a tap. You have to get up and scan the tag. Friction creates intention. Impossible to bypass. No hidden button, no cheating. The tag is the only key. Not another screen time app. Lock doesn't track your time. It makes scrolling impossible. FEATURES • NFC-based blocking with up to 5 paired tags (home, office, wallet) • Granular app picker by category (Social, Games, Tools) or search • Manual mode to try Lock without a tag • Configurable grace period (15s, 30s, 1m, 2m) to cancel accidental blocks • Emergency unlocks with adjustable duration (2, 5 or 10 min) and number (0 to 3) • Session timeout (2h to 8h, or unlimited) as a safety net • Statistics: streak, total sessions, weekly focus chart, session history • Light, Dark, and System themes SAFETY Lock is not a prison. You always stay in control. • Emergency unlocks give temporary access when you really need it • Automatic timeout deactivates blocking after a set duration if you lose your tag • Grace period lets you cancel an accidental block ACCESSIBILITY SERVICE Lock uses Android's Accessibility Service API to detect when a blocked app is opened, so it can return you to the home screen. This is the only reliable way to block apps on Android, and it is the core functionality of Lock. The Accessibility Service is used exclusively for app-blocking detection. Lock only reads the package name of the foreground app. It never reads screen content, never captures input, never records audio, and never sends any data off the device. You enable this permission yourself during onboarding, with a clear explanation of why it is needed. You can disable it at any time in Android Settings > Accessibility. PRIVACY Lock is 100% private. No analytics. No tracking. No account. No ads. No internet connection of any kind. Your profiles, tags, and statistics stay on your phone. Export them yourself if you want to switch devices. REQUIREMENTS • Android 14 or later, with NFC • Any standard NFC tag 100% free. No account. No ads. No in-app purchases. Privacy: https://lock-app.fr/privacy
