Find your phone without internet.

Your phone goes missing. Mobile data is off. You want to know where it is and do something about it.

Protect My Phone lets you check on it from another phone you have already connected. Open the app, choose your missing phone and tap the action you need. The app handles the messages for you.

• See its live location and when it was last reported.

• Make it ring to help find it nearby.

• Lock the screen remotely after enabling the lock feature.

• Check its battery and connection details together.

If the phone is moving, turn on location updates once. It will report changed locations at your chosen interval until you stop it. You can connect multiple phones and view their reported locations on a map. A recovery message is also available for phones set up with advanced device management.

Set up your phones before you need it. Install the app on both, connect them and confirm the pairing by scanning the QR codes. No app account is needed.

How it works

The app uses end-to-end encrypted SMS between paired Android phones, with no command server. Built with Kotlin and open source on GitHub. Your phone needs power and SMS coverage; online maps need internet. Use only on your own devices or with the owner’s consent.

Get the app

Google Play restricts SMS permissions for device locators and remote control, so this version is available directly from my website. Tap Visit above to download the official signed APK. You can also read the source code or contribute on GitHub.
