Description
LightBlue® by Punch Through® Your ultimate BLE debugging and development toolkit. Trusted by BLE developers and engineers since 2012 to scan, inspect, and troubleshoot Bluetooth Low Energy devices with precision.
Scan For Peripherals Discover, connect, and interact with nearby BLE devices. Quickly view advertising peripherals, sort by signal strength (RSSI), and connect with a single tap. Once connected, explore the device's advertisement data, services, and characteristics.
Isolate SDK Issues Simplify debugging by pinpointing issues in your BLE SDKs. LightBlue lets you isolate your app's business logic and focus on core tasks like connecting, scanning, reading, writing, and receiving notifications, built on years of BLE development experience and platform best practices.
Mimic Your Devices Prototype your application by creating virtual BLE peripherals. Build a profile from scratch or clone an advertising peripheral to mimic your product's functionality, even before your own firmware is ready.
Key features:
- Scan and discover BLE peripherals nearby - Browse services and characteristics in detail - Read, write, and subscribe to notifications and indications - Send data from notifications to AWS IoT or Adafruit IO via Cloud Connect - Write to characteristics in Hex, Octal, Binary, Decimal, or ASCII - Clone peripheral profiles or build your own from scratch - Advertise as a custom peripheral to simulate your device - Thoroughly log and share BLE events - Available on iPhone, iPad, Mac, and Android
LightBlue started in 2012 as an internal tool. Punch Through built it to test and debug BLE devices while working on client projects. It worked well, so we shared it with the community. We've kept it free ever since. Today, LightBlue is used by solo developers and engineering teams alike, including inside some of the world's most respected tech and device companies.

This BLE app has the clearest interface in my experience, and helped me poke around some devices.
★★★★★Al Arms· Apr 7, 2025
Found my hearing aid, not the easiest of apps to find BT devices (I know that's not it's primary function) but you work it out and understand the signal strength indicators it actually gets very easy. Thank You so much. This app beats all the so-called "Bluetooth finders" hands down.
★★★★★Nukhdiha Omar· Dec 25, 2025
Used fully. I found my device just follow the reading. When it near, the higher the reading
★★☆☆☆Markie· Jul 13, 2026
Did not detect missing unpaired Bluetooth, glitch in full blue bars with score of 0 with no info on the device and signal didn't change, restarted devices twice with no change, sloooww to change signal strength when moving around
★☆☆☆☆Keith Pennington· Jun 19, 2025
From the value write page, you can not access the backspace 0 or done buttons because the screen is set too low. Those buttons are behind the cancel, homepage, and back. Buttons.
★☆☆☆☆Saurabh P· Aug 5, 2025
The application doesn't work well with iPad A16, if something needs LE privacy it's not able to connect to the services nor able to initiate bonding.
