The battery menu Apple never finished
macOS has shipped essentially the same battery menu for a decade: two low warnings, a percentage, and nothing else. Battery Guard is what it should have grown into.
What macOS leaves on the table
Every one of these is something the built-in menu simply can't do.
macOS only warns you at 10% and 5%.
Set alerts at any level you want — and style each one.
No idea how worn your battery really is.
Health, cycles, and a replacement forecast, charted over time.
Charging to 100% all day quietly ages the battery.
Set an 80% alert so you know exactly when to unplug.
The battery menu vanishes the second you click away.
Desktop widgets keep charge, health, and time-left in view.
Principles we won't compromise on
Private by design
No analytics, no tracking, no account. Battery Guard has no network access at all — health history, alerts, and readings are computed and stored only on your Mac, and nothing is ever sent off your device.
Genuinely native
Written entirely in Swift and SwiftUI. No Electron, no bundled browser, no 300 MB install. It sips CPU and energy because it's built the way a Mac app should be.
Alerts you control
macOS gives you two fixed warnings. Battery Guard lets you create as many rules as you like, at any level, each with its own sound, banner, and screen-edge glow.
Made to last
An 80% unplug alert and temperature warnings help you build battery-friendly habits — and the health forecast tells you, in months, when it's really time to replace it.
See the difference for yourself.
