Your watch moves away, your phone locks.
WristLock monitors the Bluetooth connection with your paired devices—your smartwatch, fitness tracker, headphones—and locks the screen as soon as one disconnects. If you get up from the table and leave your phone behind, or if someone takes it, the screen will already be locked when they reach it.
HOW IT WORKS
1. Choose which of your paired devices you want to monitor.
2. WristLock listens for Bluetooth disconnections in the background.
3. When one disconnects, it starts a timer that you set.
4. If the device reconnects in time, nothing happens. If not, the screen locks.
That timer exists for a reason: Bluetooth sometimes drops on its own. With a few seconds of grace, a momentary interruption won't lock you out of your own phone.
FEATURES
• Multiple devices simultaneously, each of which can be activated separately.
• Configurable delay: immediate, 5, 8, 10, or 30 seconds.
• "Screen-on only" mode, so it doesn't work when your phone is in your pocket.
• Restarts automatically when you turn on your phone.
• Optional notification when locking, so you know why.
• Light, dark, or system theme.
• Spanish and English.
PRIVACY
WristLock does not have internet access. This isn't a promise: the app doesn't even request permission, so it's technically unable to send anything to any server.
• No accounts or registration.
• No analytics, no telemetry, no advertising.
• No third-party SDKs that collect data.
• Your device MAC addresses stay on your phone: they are not sent to the backup.
Your phone locks automatically when your watch moves away. No internet or data required.
