WattageMonitor
Real-time charging-wattage display, in your macOS menu bar.
A lightweight macOS Menu Bar app that shows the live wattage your laptop is pulling from its charger. Built with Swift and AppKit, polls `ioreg` with configurable cadence (1 / 5 / 10 / 30 s), reacts instantly to plug/unplug events, and can hide itself when running on battery.
