Bluetecht is a Bluetooth Low Energy (BLE) diagnostic tool for developers, engineers, makers and anyone who wants to see what their nearby BLE devices are really doing.

Scan for nearby devices, measure signal strength, inspect advertising data, explore GATT services, read and write values, monitor connections and record sessions – all in one clean, fast app.

FREE FEATURES
- BLE scanner – discover nearby Bluetooth Low Energy devices in real time
- Live signal strength (RSSI) for every device
- Device details – name, address, manufacturer, advertised services, TX power and raw manufacturer data
- Works in 5 languages: English, Turkish, German, Spanish and French (switch inside the app, no restart)

BLUETECHT PRO (one-time purchase, no subscription)
- GATT Explorer – connect to a device, discover services and characteristics, read values, write hex data (with or without response) and subscribe to notifications and indications
- Value decoding – view data as hex and UTF-8 or decode it as UInt8/16/32/64, Int8/16/32/64, Float32/64 in little or big endian
- Live signal graph – watch RSSI over time with signal quality and trend indicator
- Connection Monitor – keep chosen devices connected, with automatic reconnection after unexpected drops, a connection event history and a weak-signal alert with your own RSSI threshold
- Session recording – log discoveries, connections, reads, writes, notifications and errors, then search and filter the log
- Export – share sessions as JSON or CSV for spreadsheets and further analysis
- Device history – every device you have seen is saved automatically, including the services you discovered
- Advanced filters – filter the scan list by name, minimum signal strength, connectable devices only, or advertised service

PRIVACY FIRST
All scan, session and monitoring data stays on your device. Bluetecht does not require an account, does not collect personal data and does not send your data to any server. There are no ads.

GOOD TO KNOW
- Bluetecht works with Bluetooth Low Energy devices. Classic Bluetooth (BR/EDR) devices such as many headsets and speakers may not appear in the scan.
- Some devices use randomized Bluetooth addresses, so the same device can occasionally appear as a new entry.
- On Android 12 and later the app asks for the "Nearby devices" permission. On Android 11 and earlier, Android requires the location permission (and location services) for Bluetooth scanning – Bluetecht never uses it to determine your location.
- Connection Monitor shows a notification while it is keeping devices connected in the background. Battery-saver settings on some phones may limit background activity.
