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.

Who are we?

We are part of the Technical University of Darmstadt in Germany. This project is part of a scientific research from the Secure Mobile Networking Lab. Our goal is to protect privacy and to find out how many people are opposed to tracking.
In this app you can voluntarily participate in a research study that will share anonymized data with us.

This app will never get monetized by showing ads, in-app purchases or anything else.

So much user error. Admittedly, the app is so close but could benefit from even an amateur focus group to work on the explanation of features. Perhaps just a dismissible "Tool Tip" whenever the user access a feature for the first time. Somebody thought the map should show whatever they've gone - not just the locations they've been at which the same device has been detected. Kinda silly. This app should be a public right. So happy MIT stepped up!

Maybe I'm missing something, but this app did not find an airtag that is not mine but actually belongs to the government. I volunteer and the airtag is on keys they gave me. I lost the keys in my bedroom. I tried finding them using the new function on Android. It found nothing. A couple months later I found the keys the old-fashioned way. The airtag still makes noise. It's 2 feet from me and this app did not find it. What could be the reason? I tried various setting changes and still no luck.

The most recent iteration (10/08/2023) of this app is easy to install and intuitive to operate. At the bottom of the screen are four icons. Left to right: Dashboard, Scan, Devices, Settings. The Scan page takes about a minute to run a scan. Be patient. However, running a scan manually does not change the time shown on the Dashboard for the Last scan, which is strange. Otherwise, a wonderful app, much needed during these days. Thank you for developing it and for offering it without charge.
