BLE Buddy
See every Bluetooth device around you.
The BLE explorer that macOS should have built in.
The Problem
macOS gives you almost no visibility into Bluetooth Low Energy devices. If you're developing a BLE peripheral, debugging a connection, or just curious about what's broadcasting nearby, you're stuck with command-line tools or expensive commercial software. There should be a simple, native app for this.
BLE Buddy makes BLE exploration easy
Scan for nearby devices and watch them appear in real time. Tap into any device to inspect its services, characteristics, and descriptors. Open a terminal connection for direct communication. BLE Buddy automatically decodes common devices so you get useful information instead of raw UUIDs.
What you get
- Real-time device discovery with signal strength indicators
- Full service and characteristic inspection
- Smart decoding for AirTags, fitness trackers, wireless headphones, smart home sensors, and more
- Terminal connection mode for real-time communication with BLE devices
- Clean, intuitive interface designed for clarity
Why BLE Buddy?
- Native macOS app, not a clunky cross-platform wrapper
- Free, no subscription
- Auto-decodes common device types so you see meaningful data
- Built-in terminal for direct device communication
- No account or signup required
Great for
- macOS and embedded developers building BLE applications
- Students learning about Bluetooth protocols
- Hardware hackers and makers working with BLE peripherals
- QA engineers testing Bluetooth connectivity
- Anyone curious about the wireless devices around them
