Overview
Dotwatt is a battery manager for the Mac menu bar, written in Swift for Apple silicon. It replaces the battery icon in the menu bar and puts the controls macOS hides one click away.
- Time left, measured: a first estimate 15 seconds after you unplug, settled within two minutes.
- The apps spending the charge, for now, today and the last seven days. Quit one from the list and Dotwatt measures the draw again: the watts before and after, and the time gained.
- A charge limit from 80 to 100%, using the charging control built into macOS (26.4 or later). Charge to full once, or be full by a time you set.
- Low, Automatic and High Power in one click, and Low Power by itself below a level you pick.
- Stay awake until you stop it, for a set time, while an app runs, or only while coding agents such as Claude Code, Codex and Cursor work.
- Alerts to plug in and unplug, and when one app drains unusually fast.
- A record of every night asleep, battery health month by month, and a battery report in one file.
- System monitors: processor and graphics load, memory, disk, network, temperatures and fans.
- Eight actions for the Shortcuts app, dotwatt:// links and two keyboard shortcuts that work from any app.
No account and no telemetry: the history stays on your Mac.
