AirGuard identifies tiny-trackers, like Samsung SmartTags or Tiles, that are following you and forwarding your location to a third-party. If a tracker is detected will get a notification. The iPhone is able to warn you if someone uses an AirTag to track you, but there is no such protection against Samsung SmartTags or Tile trackers. AirGuard adds this layer of protection so you can feel safe in your daily-life. With the scan option, you can always scan your surroundings and discover hidden trackers. You can search for a specific tracker and it tells you how close you get to it. When you reach 100% you found the 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 iPhone to find Samsung SmartTags and Tile 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 at different locations (to make sure its not your neighbour) the app sends you a notification. All this happens locally on your device and the private information, like location, tracker ids, etc will never leave your device. Who are we?
