BLE Scanner: Bluetooth Sniffer

Most Bluetooth apps hand you a list of hex addresses and leave you to guess. BLE Scanner names what is broadcasting, decodes what it is saying, and walks you to it.

Built for engineers bringing up BLE hardware, technicians commissioning devices on site, and anyone who wants to know whether something nearby is quietly following them.

No ads. No account. No sign up. Open it and scan.

FIND ANYTHING FAST
Every nearby BLE device appears in real time with a live signal history, search and filters. Sort by signal, name, last seen, or the devices you saved.

KNOW WHAT IT IS, WITHOUT PAIRING
AirPods, Beats, iPhone, iPad, Mac, Apple Watch, HomePod and HomeKit accessories are read straight out of the advertisement, including battery levels where the device broadcasts them. Vendor names resolve from the IEEE registry for almost every device on a fixed address.

WALK STRAIGHT TO IT
Locator turns signal strength into a distance estimate with Kalman smoothing, a direction arrow that sharpens as you move, and haptic ticks that speed up as you close in. Good for one unit in a full rack, a sensor behind a wall, or a tag lost in a couch.

SEE WHAT A PHONE NORMALLY HIDES
Android hands over the real Bluetooth address, and this app tells you what that means. Public, static random, resolvable private or non resolvable private, explained in plain language, so you can tell a device that changes identity every few minutes from one that can be recognised anywhere, forever. The complete raw advertisement is there too, byte for byte.

CHECK WHETHER SOMETHING IS FOLLOWING YOU
The privacy sweep collects every device broadcasting in a way that lets it be followed, worst first: Find My broadcasters, permanent addresses, beacons advertising ten times a second, and devices offering nothing that identifies them. Most of what it finds is somebody's headphones. What matters is the one you do not recognise that keeps turning up.

INSPECT GATT
Connect and browse every service and characteristic with decoded names, UUIDs and permissions. Read values live. Pro adds writes and notification subscriptions.

DECODE ADVERTISEMENTS
iBeacon, Eddystone URL, UID and TLM, and raw manufacturer data, parsed so you can check a beacon payload without writing your own tooling.

WHAT IS FREE
Scanning, live signal history, GATT browsing and reads, saved devices and three AI identifications, with no ads and no account, forever.

WHAT PRO ADDS
Model level identification instead of a generic label. The named privacy and tracker signals behind each flag. What an address type means for being followed. Unlimited identifications, including one tap to identify every unknown device at once. GATT writes and notification subscriptions.

Weekly, monthly and yearly plans, or a one time lifetime unlock. Payment is charged to your Google Play account at confirmation. Subscriptions renew automatically unless cancelled at least 24 hours before the current period ends. Manage or cancel yours in Google Play at any time.
