This release does not have a Play Store Description, so we grabbed one from version 1.0.2:

Vanced manager can easily install and uninstall vanced and microg, has various settings for customisation and better experience. The Manager comes with an easy-to-use interface, support for background download and installation*

*Due to changes in Android Oreo and up, and because of aggressive battery optimisations in some ROMs, feature may not be available for all devices.
