Battery Alarm v1.0.0-beta
A free macOS menu bar utility that does one thing well: it sounds an alarm the moment your battery drops to 20%, so you never glance down to find your Mac already dying.
Why this exists
I'm notorious for running my battery all the way to empty — deep in something, forget to plug in, and only notice when the screen's already fading to black. Battery Alarm exists so the sound catches me at 20%, while there's still time to grab a charger.
What it does
🔊 Plays a sound alarm when battery charge drops to 20%
🍎 Lives quietly in your menu bar the rest of the time
⚡ Install it and forget about it — no setup required
Notes on this beta
This is an early build — the core alarm-at-20% behavior is in place and tested on macOS Monterey. If you run into issues or have feedback, please open an issue on this repo.
