GMSCore is a fork of MicroG (GmsCore), which originally created to work for ReVanced/ReVanced Extended Apps.


What is GMSCore?

GMSCore is a must-add-on application for Android devices that helps users log in with their Google accounts in apps such as ReVanced YouTube Extended, ReVanced Music Extended and other ReVanced Apps which require Google Authentication.

Basically, GMSCore is purely based on official GmsCore by microG Services, which is a FLOSS (Free/Libre Open Source Software) framework to allow applications designed for Google Play Services to run on systems where Play Services is not available.

There are not many features to discuss as its only main objective is to provide Google services to our apps.

Google Authentication

ReVanced Extended apps do require Google authentication when you want to see your YouTube History, Subscribers, Playlists and more.


The Project is mainly designed for people who are privacy-focused at all times. Since GMSCore is a forked version of the official GmsCore, it does the same.
