BLE Scanner: Bluetooth Sniffer

See every Bluetooth signal around you and finally understand what each device is doing. Whether you are bringing up a new board, chasing a flaky connection in the field, or checking whether something is quietly tracking you, you get clear answers in seconds.

Built by a team that ships BLE hardware, so it works the way engineers actually think. No ads, no account, no sign-up. Open it and start scanning.

What you can do:

Find anything fast. Scan every nearby BLE device with live RSSI graphs and smart filtering, so the device you care about never gets lost in the noise.

Know your gear without pairing. Read AirPods, Beats, iPhone, iPad, Mac, Apple Watch, HomePod, and HomeKit accessories at a glance, including battery where available.

Walk straight to a lost device. Locator mode turns signal strength into real distance with Kalman smoothing and path loss estimates, and the haptics speed up as you close in.

Stay safe from unwanted tracking. Spot unknown AirTags and stealth trackers that follow you between locations before they become a problem.

Debug GATT in real time. Inspect every service and characteristic, then read, write, and subscribe to notifications without leaving the app.

Make sense of raw advertisements. Decode iBeacon, Eddystone, and manufacturer data so you can verify firmware and beacons quickly.

Prove what happened. Record and replay full BLE sessions for debugging, reporting, and QA, and stream events to your own HTTPS webhook in real time.

The result is less guessing, faster fixes, and confidence that nothing around you goes unnoticed.

Tap Get and scan everything around you. It is free to start.
