Feature
Custom battery alerts
macOS only warns you at 10% and 5%, then nags. Battery Guard lets you build your own alert rules — fire at 80% to unplug, at 40% to find a charger, at 20% before a meeting — each with its own banner style, sound, and a screen-edge glow you can't miss.
What you get
- Unlimited low-battery and charged-enough rules
- Per-rule sound, banner position, and border glow
- Plugged / unplugged and temperature warnings
- A full-screen critical warning across every display
Alerts at any level, with their own sound, position, and glow.
