AirGuard is a free and open-source tracking protection app for iPhone developed by Technische Universitaet Darmstadt. The app aims to identify and notify users of tiny-trackers like Samsung SmartTags or Tiles that may be tracking their location and sharing it with third parties. It provides an additional layer of security beyond the iPhone's built-in protection against AirTags, ensuring users can feel safe in their daily lives.

With AirGuard, users can scan their surroundings to uncover hidden trackers, search for specific trackers, and receive notifications when a tracker has been detected multiple times at different locations. The app operates locally on the device, safeguarding user privacy by ensuring that no sensitive information leaves the user's iPhone.
