Event driven, no polling. Idle CPU is 0.0%; sensors are read only while a window is visible.

brew install --cask doguyilmaz/tap/battistics

Or download the DMG from Releases and drag Battistics to Applications.

Either way updates arrive in-app: Battistics updates itself, so Homebrew is told to leave it alone once installed.

brew install xcodegen
make run    # debug build and launch
make test   # unit tests

Run make gen and open Battistics.xcodeproj to work in Xcode.

Runs entirely on your Mac. The only network request is the optional update check.
