Bluetooth scanner and tracker detector. Name, decode and find every BLE device.
Most Bluetooth apps hand you a list of hex addresses and leave you to guess. BLE Scanner is a Bluetooth scanner that names what is broadcasting, decodes what it is saying, and walks you to it, whether that is a lost earbud, a beacon or a tracker you did not put there. 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. On Android 12 and later, scanning needs no location permission. FIND ANYTHING FAST A Bluetooth Low Energy scanner that shows every nearby BLE device in real time, with its RSSI signal strength, 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. BLUETOOTH FINDER: 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. As a Bluetooth device finder it works on anything that is still broadcasting: earbuds out of their case, a smartwatch, a fitness band, a hearing aid. A device that has gone quiet, such as earbuds closed in their case, cannot be seen by any app, and this one will not pretend otherwise. 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, so it doubles as a BLE sniffer for advertising packets. TRACKER DETECTOR: CHECK WHETHER SOMETHING IS FOLLOWING YOU The privacy sweep collects every device broadcasting in a way that lets it be followed, worst first: AirTags and other 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 A beacon scanner as well: 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.
