Battery Meter Overlay is a free utility application for mobile developed by Soboku Apps. It is a lightweight tool that lets users create and place a persistent and floating battery meter on top of all running apps. It displays the current charge levels of their devices for quick reference.

Glanceable battery levels

Batter Meter Overlay appears as a persistent floating icon in either the center of your notification or navigation bar. It can be further customized with preset themes that change the icon and number font style as you like.

It will also dynamically change colors to show battery levels from low to fully charged. There's also an optional Pro Key to unlock more features and granular control over scale, color, and positioning if you want. One small bug worth mentioning is that the icon doesn't change when charging sometimes.

Simple yet handy

In conclusion, Battery Meter Overlay is a simple yet handy tool that provides battery level information at a glance. It's easy to use and can be customized with various theme icons and colors. Also, the Pro Key is worth considering as it unlocks plenty of other useful options to make the most out of this app. Give it a try yourself.
