macOS does the bare minimum. Battery Guard does the rest.
The built-in battery menu hasn't really changed in years. Here's what it leaves on the table.
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.
Everything you wish the battery menu did
Six pillars, each one a place macOS stops short.

Learn moreBuilt for the moments your battery actually matters
Working from a café
No outlet in sight? Set a 30% alert that's impossible to miss and a 15% full-screen warning, so you save your work long before macOS would ever say a word.
Making the battery last years
Set an 80% unplug alert, keep an eye on temperature, and let the health forecast tell you when capacity is really starting to slip — so your Mac's battery outlives its warranty.
Deep focus, no nags
Battery Guard dismisses macOS's repetitive low-battery banners and replaces them with a single calm alert at the one level you actually care about.
Presenting without panic
Before a talk, set a high alert threshold and watch live time-to-empty in the menu bar. No surprise shutdowns mid-slide.
“It's the battery app I always wished macOS shipped with. The custom alerts alone are worth it.”
Built by one developer who cares
Battery Guard is a 100% native Swift app — no Electron, no web view, no telemetry. It's built and maintained by an indie developer who got tired of macOS's 10%-and-5% battery warnings and decided to build the app Apple never did. Every reading is computed on your Mac and stays there.

Questions, answered
Any Mac running macOS 14.0 or later, on both Apple Silicon and Intel.

Every plan unlocks the same Pro features. Choose a monthly ($2.99) or yearly ($9.99) subscription, or a one-time Lifetime purchase ($14.99). All are handled by the App Store.
No. Battery Guard is a tiny native Swift app that samples in the background every 30–60 seconds. It uses a negligible amount of CPU and energy.
