AirGuard - AirTag protection

Secure Mobile Networking

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.

Ratings and reviews

Designed to be useful not to be pretty. The UI/UX were clearly not a priority for the developers, but that's ok because the functionality is great. I tested a few Bluetooth LE beacon tracking apps and this one is by far the best for tracking Apple products (eg AirTag, 'Find My' accessories, AirPod, Mac). So much better and useful than Apple's own Tracker Detect. However the Scan results are a bit chaotic and jump all over the place and I would have liked it to show the UUID/Major/Minor info too

Handy app! A few nice changes would be: If the Scan results didn't jump around so quickly. If a pin on the map views could be selected to view timestamp info. If you could record a note/description/label for devices.

There's a Tile (I don't own any) that is apparently tracking me. It shows multiple locations that I actually have been (one an hour away), but I never get an option to play a sound, and have not been able to find it. Is there any way to see a log of timestamps and detected locations?

What's new
