Turn your Android device into a clear, real-time Bluetooth Low Energy (BLE) scanner. Scan nearby devices, compare live signal strength, and use proximity estimates to help locate lost accessories.

Find lost Bluetooth devices

Looking for wireless earbuds, headphones, a smartwatch, fitness band, speaker, or another Bluetooth accessory? BLE Finder detects actively advertising BLE devices within range and updates their signal strength as you move.

Walk toward a stronger signal to narrow down your search. Detection depends on the device being powered on, within range, and actively broadcasting a Bluetooth signal.

Review nearby and unfamiliar signals

Explore Bluetooth signals around you, including accessories, trackers, wearables, smart-home devices, and IoT sensors. Device names and manufacturer information can help you recognize your own equipment and investigate unfamiliar BLE devices nearby.

BLE Finder only detects devices that are currently broadcasting Bluetooth. It cannot detect devices that are powered off, out of range, or using a different wireless technology.

Live signal and proximity guidance

Follow live RSSI readings, estimated distance, and a proximity indicator while moving around. Signal strength can change because of walls, furniture, interference, device orientation, and transmit power, so distance values should be treated as estimates rather than exact measurements.

Detailed BLE information

Select a detected device to view available information such as:

- Advertised device name
- Manufacturer information
- Service UUIDs
- Live RSSI and signal history
- Estimated distance and proximity
- Last-seen time
- Connectable status

The information shown depends on what each Bluetooth device chooses to advertise.
