Energy Ring is an Android app developed by Vove that provides an innovative way of visualizing your battery level. The app creates a ring around the camera cutout on your phone's screen, which changes color as the battery level changes. The app is free to use and falls under the category of Utilities & Tools.

Energy Ring has several features, including auto-hide in full screen and on horizontal orientation. The charging animation is also a unique feature that provides a delightful experience while charging your phone. The app is not affected by resolution, making it compatible with different screen sizes. Additionally, the app also flashes the ring on the screen-off mode, providing a notification reminder.

Energy Ring has a feature where the app blinks the ring after 5 seconds of receiving a new notification while on screen-off mode. It also allows users to set a do-not-disturb time period from 00:00-07:00, where double-tapping the screen will not activate the face unlock feature. However, the face unlock feature may not be available while double-tapping the screen.

Overall, Energy Ring is a unique and innovative app that provides a new way of visualizing your battery level. The app is available on Github, and it is currently compatible with only the main chat applications in China.
