BaBar is a free Android app developed by matsumo that provides a simple and visually appealing way to monitor your device's battery status. With BaBar, you can easily check your battery level at a glance.

The main feature of BaBar is its battery bar, which changes color based on the remaining battery percentage. When your battery level is between 80% and 100%, the bar is displayed in blue. As the battery level decreases, the bar color changes to green (60%-80%), yellow (40%-60%), orange (20%-40%), and red (0%-20%). When your device is charging, the bar turns pink.

BaBar also offers a more customizable version called "OniBaBar," which allows you to customize the bar color, height, and other settings according to your preferences.

Overall, BaBar is a simple yet effective app for monitoring your device's battery level. It provides a visually appealing way to keep track of your battery status without the need for complex battery widgets or intrusive notifications.
