A tool to monitor, analyze and find BLE devices around you.
About this app
DISCLAIMER: This project is developed solely for educational, security research, and personal investigative purposes. The author does not endorse or encourage any use of this software for unlawful or unethical activities. You are solely responsible for ensuring your use of this tool complies with all applicable laws and regulations.
Bluetooth Low Energy (BLE) is a widely used wireless protocol that powers a huge variety of devices around you — from headphones, smartwatches, and fitness trackers to AirTags, IoT devices, game controllers, and even modern intimate gadgets. BLE devices communicate by broadcasting small packets of data, which can include device identifiers, metadata, and other information necessary for connectivity.
These broadcasts, while essential for device functionality, can also be used to track your presence and movements. For example, a cheap pair of wireless headphones may expose a persistent identifier publicly. Anyone listening to BLE packets nearby — whether governments, companies, or malicious actors — could potentially use that information to track you without your consent.
Fortunately, many modern devices implement privacy features in BLE to prevent tracking, such as randomized addresses and limited advertising. BLE Radar helps you distinguish between devices that protect your privacy and those that might be trackable. By analyzing BLE traffic in your surroundings, the app gives you insight into which devices are safe to use.
Beyond analysis, BLE Radar can help protect you in real-time. The app can alert you when a suspicious device is nearby or if a device is moving with you over time, giving you an early warning against potential stalking or unwanted tracking. You can configure alerts based on device identifiers, types, or behaviors to fit your security needs.
By making this app, the goal is to empower you with knowledge and control over the BLE devices in your environment. Understanding which devices are broadcasting trackable information and which are privacy-conscious allows you to make informed decisions about what you use, wear, and interact with daily.
In general, the app is capable:
* Scan, analyze and track Bluetooth devices around; * Create flexible filters for the radar; * Deep analysis of the scanned BLE devices, getting data from the available GATT services; * Gatt services Explorer; * Define the device type by metadata; * Define approximate distance to the device.
Bluetooth Radar does not collect or send your personal or geolocation data. The project is fully opensource and available on GitHub.

Installation Guide
Open Settings on your Android device
Go to Security → Unknown sources (or Install unknown apps)
Enable "Allow from this source" for your browser or file manager
Open the downloaded APK file from your Downloads folder
Tap "Install" and wait for installation to complete
Launch the app from your home screen
Make sure to re-enable Unknown Sources restrictions after installation for security.
How to install this safely
How to verify the file you downloaded
Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.
What the signing certificate proves
Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be f.cking.software is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.
How to roll back to an earlier version
If the current release misbehaves, 0.32.0-beta is the last build before it. Android will not install an older version code over a newer one, so you must uninstall BLE Radar first — which clears its local data unless you have a backup. Reinstall the older APK only if its signing fingerprint matches the build you already trust, and check the API range: an older release may target an Android version your device has moved past.
Why we list sources instead of hosting everything
The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of BLE Radar, and a listing is removed when the evidence for it stops holding up.
