# Install/Update

During integration if your app is already on the App Store, MoEngage would need to know whether your app update would be an actual UPDATE or an INSTALL.

Have logic in place to differentiate Install and Update and make use of the `setAppStatus()` method to track the same as described:

<CodeGroup>
  ```javascript JavaScript theme={"theme":{"light":"github-light","dark":"github-dark"}}
  import ReactMoE, {
    MoEAppStatus,
  } from "react-native-moengage";
  //For Fresh Install of App
  ReactMoE.setAppStatus(MoEAppStatus.Install);
   // For Existing user who has updated the app
  ReactMoE.setAppStatus(MoEAppStatus.Update);
  ```
</CodeGroup>
