What is the different with firebase

[xiaohui-hiwintech]

Currently, I have a react web app and a react-native mobile app, I want to integrate an analytics tool into both the web app and mobile app, so I found this repo, and also I found the firebase repo for web and firebase repo for RN, so I'm confusing, react-ga is only for the web app, right? I should use the firebase instead of the react-ga, since I need to integrate to mobile app right?
