It's neat that it shows the Bose devices' battery level.

AFAIK the Apple APIs don't display that on macOS because it doesn't fully implement the Bluetooth spec (it does on iOS).

One of my apps gathers battery info for all almost Apple devices (and some non-Apple), but I had trouble getting battery info for Bose, Logitech, Sennheiser (etc..) bluetooth devices without very low-level hacks that I wouldn't ship in an app destined for casual users.
