Gauge

A private device-health companion: device info, live charging analytics and battery widgets.

What it does

  • Live battery: watts, current, voltage, temperature, time to full and estimated health, with graphs
  • Charge history with a power curve per charge, and a Charger Lab that ranks your chargers
  • Hardware, system, network, camera, sensor and thermal details
  • Hardware tests (display, touch, speakers, sensors, biometrics…), a floating monitor and a status-bar reading
  • 16 configurable home-screen widgets and themes, including Studio

How it’s built

  • Multi-module native Android layer in Kotlin, bridged to Flutter with type-safe Pigeon channels
  • JVM unit tests for sysfs and /proc parsing, estimators and alerts
  • Every widget snapshot-tested with Paparazzi at three sizes × two themes
