Bluetility

What is Bluetility?

Bluetility is a native macOS utility for working with Bluetooth Low Energy devices. It helps developers, testers, and hardware enthusiasts discover nearby BLE peripherals, connect to them, and inspect the services and characteristics they expose. Users can read and write characteristic values, subscribe to notifications, and review advertising data while exploring device behavior. The app also includes logging tools that help with troubleshooting and repeated testing workflows, including saving logs as CSV files. Bluetility is published by Joseph Ross as an open-source desktop app for Mac users who need a focused BLE browser and debugging tool.

Key features

• Scan for nearby Bluetooth Low Energy peripherals
• Sort discovered devices by received signal strength
• View advertising data for detected devices
• Browse services and characteristics on connected peripherals
• Read and write characteristic values
• Subscribe to characteristic notifications
• Log characteristic activity and save logs as CSV

Safety overview

Status: Mostly safe

Bluetility is a Bluetooth utility, so access to Bluetooth is normal for its purpose. It can communicate with nearby BLE devices and read or write characteristic data when you choose to connect, which is useful for testing but means actions in the app can affect connected hardware behavior. Use it with devices you recognize, and avoid changing values on production or safety-critical peripherals unless you know what the commands do.

Recommendation: Keep Bluetility if you use your Mac to inspect, test, or troubleshoot Bluetooth Low Energy devices. If you no longer work with BLE hardware, you can remove it without affecting macOS beyond losing this tool and its saved app data.
