This app automatically checks your smartphone’s battery level every hour and provides notifications, icon changes, and a clear history log. It is designed to be simple, reliable, and easy to use.

By using Android’s “Exact Alarm” feature (Android 12 and above), the app ensures that battery checks run consistently every hour, regardless of power-saving restrictions. It performs only short, efficient tasks and does not run continuously in the background, keeping battery consumption to a minimum.
