Juice

Juice reads power‑source data from macOS through the IOKit framework and replaces the standard battery indicator with a user‑defined textual scale. It monitors changes in charge level and other power‑source properties, then displays the corresponding string from a custom scale, allowing users to personalize how battery status is presented.

Users can create or edit scales as property‑list (plist) files that map percentage ranges (detents) to arbitrary strings and provide a title and default fallback. Scales are managed in the preferences window, where new plist files can be added, rescanned, and selected from a drop‑down list. The application stores custom plist files in the user’s Application Support directory, and the UI lets users generate a template plist automatically.

The project is open‑source and distributed as a free‑tier, stable macOS utility. It can be built from source with Xcode or installed from pre‑compiled binaries released on GitHub. Contributions are welcomed via pull requests.
