About MetaRadar

MetaRadar, also described as Bluetooth Radar, is an open-source Android tool for monitoring the Bluetooth Low Energy (BLE) environment around you. It scans, analyzes and tracks nearby BLE devices, supports custom filters for the radar, and can notify you when a device fingerprint you are watching for is nearby, including alerts when a device appears to move with you over time. It also offers deeper inspection of scanned devices through a GATT services explorer, infers device type from metadata, and estimates approximate distance to a device. The project's stated aim is to help distinguish devices that use privacy features such as randomized addresses from those that broadcast persistent, trackable identifiers.

The author states the project is developed for educational, security research and personal investigative purposes, and that users are responsible for ensuring their use complies with applicable laws and regulations. The app is described as working offline and not sharing personal data or geolocation. It is distributed as a GPL-3.0 licensed repository; pricing is not stated in the source material.
