Your phone's second lock.
GuardLock watches for your trusted Bluetooth device. When it goes out of range, your phone locks itself after a short delay — an extra layer of protection if your phone ends up in the wrong hands.
Three steps to a smarter lock
No new habits to learn — GuardLock runs quietly in the background and only steps in when it matters.
Pair your device
Choose any Bluetooth device you already carry — a watch, earbuds, or your car — as your trusted "key."
Go about your day
GuardLock quietly monitors the connection in the background. No extra taps needed.
Automatic lock on disconnect
If your key device disconnects unexpectedly, your phone locks after a short delay and needs your PIN, pattern or password to reopen.
An extra layer for everyday life
Every feature exists for one reason: to help keep your data safe if your phone is left behind or taken. GuardLock adds to your normal screen lock; it does not replace it.
Quick response
Locks your screen a few seconds after your trusted device drops out of range.
Full re-authentication
Once locked, only your PIN, pattern or biometrics can get back in — no shortcuts.
Background monitoring
Runs in the background while Bluetooth is on. Switching Bluetooth off while monitoring is on locks your phone too.
Local & private
Everything happens on your device. Your device list and habits are never sent anywhere.
Clear status, always
See at a glance which device is linked and whether you're currently protected.
