Astra is a lightweight macOS menu bar app for viewing estimated system power usage.
It focuses on a small local workflow:
- current power estimate
- today, this week, and this month energy usage
- sleep, wake, and dark wake interval records
- 5-second sample collection
- 30-day local sample retention
macOS does not provide a public API for exact whole-device wattage on every Mac. Astra currently uses the SMC PSTR signal as a practical estimate and treats the result as an approximation.
- macOS 14.0+
Signed and notarized DMG builds are published through GitHub Releases. The source archives generated by GitHub are not the app distribution package.
More details are in docs/INSTALLATION.md.
Astra runs as a menu bar app. Click the menu bar item to open the popover and switch between current power, today, this week, and this month.
Local data is stored under:
~/Library/Application Support/Astra/See docs/USAGE.md for the current app behavior.
The app source is provided for review. This repository is not the full development workspace and is not intended to be built directly.
