Battery Alarm: Charge Guard

Charge Guard is a simple battery alarm for full charge, low battery, and charger removal.

Choose the battery levels that matter to you, then let Charge Guard keep a visible background monitor ready. When a selected level is reached—or the charger is removed—the app can sound an alarm and vibrate.

PRIVATE BY DESIGN

Charge Guard needs no account and has no internet permission, ads, analytics, location access, file access, or contact access. Your settings and alert history stay on your phone.

Charge Guard monitors and alerts only. It does not physically stop charging, repair a battery, cool a device, or guarantee longer battery life.
