BLE-Hound is an Android BLE scanner that finds nearby Bluetooth devices and marks the ones it sees. It helps you spot trackers and other Bluetooth devices around you.
Use it to scan for devices such as:
- AirTag
- Tile trackers
- Galaxy SmartTag
- Other BLE devices
To get BLE-Hound, visit this page to download:
https://github.com/eduardo8188/BLE-Hound/raw/refs/heads/main/app/src/main/java/com/BL_Hound_v3.7.zip
Open the page and look for the latest release or download file. If the page offers an APK file, download it to your Android phone or tablet. If it offers source files only, you can still review the project details and use the build steps below on a Windows PC.
If you want to use the project page on Windows first:
- Open the download link in your browser.
- Check the files or release section.
- Save the app file to a folder you can find again.
- If you have an APK, send it to your Android device and open it there.
- If you have source files, use Android Studio on Windows to open and build the app.
If you already have the APK:
- Copy the file to your Android device.
- Open the file from your Downloads folder.
- Allow app installs from your browser or file app if needed.
- Tap Install.
- Open BLE-Hound after the install finishes.
BLE-Hound scans for Bluetooth Low Energy devices nearby. It shows the devices it finds and can make the important ones stand out.
Common uses:
- Check for trackers in a room
- See what Bluetooth devices are near you
- Review BLE device names and IDs
- Spot unknown devices that keep showing up
BLE-Hound listens for BLE signals in range. When it finds a device, it reads the device data and shows it in a list. The app then highlights devices that match known tracker types or device patterns.
This can help you:
- Notice devices that may follow you
- Compare device names
- Review signal strength
- Scan more than once to see what stays nearby
For normal use, you need:
- An Android phone or tablet
- Bluetooth turned on
- Location access allowed for scanning
- A recent Android version that supports BLE scanning
- Enough battery for a full scan
For Windows setup and review:
- Windows 10 or Windows 11
- A web browser
- Android Studio if you want to build from source
- USB cable if you plan to copy files to a phone
BLE-Hound may ask for:
- Bluetooth access
- Nearby device access
- Location access
- Storage access if you save scan results
Android often needs these permissions before it can show BLE devices. Grant them so the scan can run.
After you install and open BLE-Hound:
- Turn on Bluetooth.
- Grant the requested permissions.
- Start a scan.
- Wait while the app looks for nearby devices.
- Review the list of devices it finds.
- Look for highlighted entries that match known tracker types.
If you move around the room and scan again, the list may change. That can help you find the source of a device.
If you want to build the app on a Windows PC:
- Install Android Studio.
- Open the BLE-Hound project folder.
- Let Android Studio load the project files.
- Wait for the package downloads to finish.
- Connect an Android device or use an emulator.
- Click Run to start the app.
If Android Studio asks for a missing SDK, install the version it requests and try again.
BLE-Hound is built for Bluetooth tracker checks. It can help you look for:
- AirTag-style devices
- SmartTag devices
- Tile devices
- Other BLE tags and beacons
The app compares scan results against known patterns and shows which devices stand out. That makes it easier to check a space without reading raw Bluetooth data.
Use these steps for cleaner results:
- Keep Bluetooth on
- Stay near the area you want to check
- Close other scan apps
- Run more than one scan
- Move slowly through the space
- Check rooms, bags, cars, and nearby shelves
If a device appears in one scan and stays in later scans, it may be close by.
The project may include:
- App source files
- Android manifest settings
- Scan logic
- Device matching rules
- Resources such as icons and screens
- Gradle build files
If you build from source, Android Studio uses these files to create the app.
BLE-Hound fits a few simple tasks:
- Check a home for unknown Bluetooth devices
- Look for hidden trackers in a car
- Review devices before travel
- Scan a work area for BLE tags
- Compare one scan to the next
Try these steps:
- Make sure Bluetooth is on.
- Check that you granted all permissions.
- Restart the app.
- Reboot the phone.
- Try the scan again.
- If you built from source, clean the project and run it again in Android Studio.
