 ## Firestack vs Firebase JS lib
 
 Although the [Firebase](https://www.npmjs.com/package/firebase) JavaScript library will work with React Native, it's designed for the web and/or server. The native SDKs provide much needed features specifically for mobile applications such as offline persistance. Firestack provides a JavaScript interface into the native SDKs to allow your React Native application to utilise these features, and more!
 
 ## Example app
 
 We have a working application example available in at [fullstackreact/FirestackApp](https://github.com/fullstackreact/FirestackApp). Check it out for more details about how to use Firestack.
