About this app

With AirGuard you get the anti-tracking protection you deserve!
The app periodically scans your surroundings for potential tracking devices, like AirTags or other Find My devices.

The AirTags and other Find My devices are simple, small and perfect to track Android users!
Without tracking warnings, as integrated on iOS, anyone could try to track your behavior by placing an AirTag in your jacket, backpack or car.

With the app you can play a sound on AirTags and find it easily. Afterward, you can view at which locations the device has tracked you. For this we use background location access. All location data never leaves your device

If no one is trying to track you, the app will never bother you.

How does it work?



AirGuard uses Bluetooth scans of your Android phone to find AirTags and Find My trackers. Every tracker that is found will be saved locally on your device.
Whenever a tracker gets detected multiple times the app will recognize this. It compares the locations where the tracker has been detected.
If a tracker is detected at least 3 times and the locations have changed (to make sure its not your neighbour) the app sends you a notification.
If this tracker is an AirTag you can play a sound to find it.

All this happens locally on your device and the private information, like location, tracker ids, etc will never leave your device.

Lowering a star. Not sure what happened, but the map disappeared when you click on a discovered device. It shows up barely at the top of the screen. Cannot expand it or see anything useful. To the main map still works showing all trackers though. S21, fully patched, running the latest version of this app.

Hi, Testing the app is fine, we evaluated the car use-case especially. One thing, the app will not notify you about the tracker when you use the car less than 35min / day. Because It needs some time to detect that the tracker is following you

I like the concept! I installed the app and dug through the source code. The biggest weakness of this app is the location data quality is poor. It looks like location comes from the GPS or network, whatever is fastest, but not whichever is most accurate. Bluetooth tracking is in the range of tens of meters which needs high accuracy to work, so the idea doesn't work, unless you get lucky and get good location data.

Hi James, that is correct, but also the location information does not need to have the highest accuracy. Location data points are useful for victims to identify if that has been an actual tracking attack or if this is the tracker of someone else (e.g. on a train). It can never be as accurate to find a device just by using location coordinates.

It seems to require the ability to track your location all the time, not only when the app is not in use. I cannot even get past the setup procedure to try this out without allowing this permission. I get that constant tracking may improve the app's ability to judge your location, but I'd prefer to make that judgement on a case by case basis. Anyone see the irony with installing an app that *needs* to track you 24/7 just to check for nefarious AirTags that *might* be tracking you, maybe?
