BLE Radar: Bluetooth Scanner

BLE Radar is a real-time Bluetooth Low Energy scanner with live signal strength (RSSI) for makers, IT pros, and anyone who needs to find a Bluetooth device. No ads, ever. No subscription. No account. Works fully offline.

Find a Bluetooth device

The Precision Finder turns signal strength into a simple hot and cold proximity meter. Walk toward stronger signal and it guides you straight to lost earbuds, headphones, beacons, and tags. It also helps you manually locate any transmitting Bluetooth device nearby by following its signal.

For makers and developers

See every advertising BLE device around you with live RSSI, then open full device detail: services, characteristics, and raw manufacturer data. Debug microcontroller and IoT projects, verify BLE beacon transmitters, check Bluetooth signal strength in the field, and use it as a pocket RSSI meter and beacon scanner. Export any scan to CSV for offline analysis.

On your wrist

BLE Radar's Wear OS tile and complication put live scanning on your watch face, so you can check for nearby devices without pulling out your phone.

Honest scope

BLE Radar scans when you tell it to. Background presence alerts for your saved devices are a Pro feature you turn on yourself, and the app shows a notification whenever it is scanning in the background. Nothing is uploaded, and there is no account.
