HD BLE Analyzer

About this app

Find any Bluetooth device around you. BLE Scanner turns invisible Bluetooth Low Energy signals into a live map you can read, follow and record.

Open the app, press start, and every BLE device advertising nearby shows up in seconds: headphones, smartwatches, fitness bands, speakers, beacons, tags, sensors, TVs and car systems. No pairing, no setup, no account.

FIND A DEVICE YOU LOST
- Pick any device and let Proximity Finder walk you to it
- Sound and vibration speed up as you close in, like a metal detector
- Plain proximity cues tell you where you stand: Cold, Warming Up, Boiling Hot, Found
- Estimated distance updates live from signal strength
- Made for a dropped earbud, a misplaced tag or a sensor behind a wall

SEE WHAT IS BROADCASTING NEARBY
- Watch every device in a live list or an animated radar view
- Read device name, MAC address, vendor and real time RSSI
- Star the devices you care about and filter the scan down to them
- Spot Bluetooth trackers and beacons advertising around you

INSPECT THE RAW PACKETS
- Open Packet Inspector on any device straight from the scan
- Decode iBeacon and Eddystone advertisements when they are present
- Check the manufacturer payload and calibrated TX power
- Read the raw advertising bytes in hex and copy them with one tap

MEASURE AND COMPARE
- Average RSSI, variance, signal frequency, first and last seen
- Session summaries, full scan history and global statistics
- RSSI trends across recent sessions and your most seen devices
- Scan for 30 seconds up to unlimited, your call
- Keep scanning in the background with the screen locked

SAVE AND SHARE YOUR DATA
- Every finished scan writes a timestamped JSON report to Downloads
- Export the whole history or just a date range
- Send reports to any app or straight to email

BUILT TO BE READ
An animated radar, neon cyberpunk colors and layouts that fit phones, tablets and foldables. Turn on high contrast when you are working outdoors or staring at signals for an hour.

YOUR DATA STAYS YOURS
This app only listens. It never pairs, never reads characteristics and never writes to anything nearby. Scans and history live in an encrypted database on your phone until you export them. No ads, no account, no cloud sync. Usage analytics are optional and switch off in Settings.

WHO USES IT
- Anyone hunting for a lost earbud, tag, remote or tracker
- Makers and engineers debugging BLE range, drops and interference
- Installers checking beacon coverage across a room or a building
- Security minded people curious about what is broadcasting around them
- Students learning how BLE advertising and RSSI actually behave

Works on Android 11 and up. Distance and proximity are estimates read from radio signal strength, so walls, bodies, antennas and interference will move the numbers.

ONE DEVELOPER, MADE IN BRAZIL
This app is built and maintained by one person in Brazil. There is no company behind it and no growth team, so what gets built next is mostly decided by what people ask for. If a feature is missing, a device shows up wrong, or something simply annoys you, write to [e-mail]. Every message gets read.
