Lockin

Lock in app

About this app

LockIn turns a physical NFC tag into your focus switch. Tap the tag to lock the apps that distract you, and tap again to unlock. No menus, no willpower battles, just a tap.

WHY LOCKIN
Most app blockers are easy to disable the moment you feel the urge. LockIn adds real friction: the apps you choose stay blocked until you physically tap your NFC tag. Leave the tag in another room and you can't cave on impulse.

FEATURES
• NFC app blocking: tap your tag to lock or unlock your chosen apps
• Focus timer: see how long your current session has lasted
• Session summaries: "you regained X minutes of your life"
• NFC alarm clock: wake up and tap the tag to dismiss; the alarm won't stop until you do
• Strict Mode: optionally prevent uninstalling LockIn during a session
• Light and dark themes
• Works entirely on your device: no account, no internet, no tracking

HOW IT WORKS
1. Choose which apps to block.
2. Tap your LockIn NFC tag to start a blocking session.
3. When a blocked app opens, LockIn shows a block screen.
4. Tap the tag again to unlock.

PRIVACY
LockIn does not collect, transmit, or share any data. Everything stays on your device. The app has no internet permission and contains no ads, analytics, or trackers.

PERMISSIONS
LockIn uses the Accessibility Service only to detect which app is in the foreground so it can show the block screen. It never reads your screen content, messages, or what you type. You stay in control and can disable it any time.

Stay locked in.
