# Install/Update differentiation

Since you might integrate us when your app is already on the App Store, we would need to know whether your app update would be an actual **UPDATE** or an **INSTALL**. Have a logic in place to differentiate between the two, and use the methods below to let the SDK know about the same:

<CodeGroup>
  ```swift Swift wrap theme={"theme":{"light":"github-light","dark":"github-dark"}}
  //For Fresh Install of App
  MoEngageSDKAnalytics.sharedInstance.appStatus(.install)

  // For Existing user who has updated the app
  MoEngageSDKAnalytics.sharedInstance.appStatus(.update)
  ```

  ```objective-c Objective C theme={"theme":{"light":"github-light","dark":"github-dark"}}
  //For Fresh Install of App
  [[MoEngageSDKAnalytics sharedInstance]appStatus:MoEngageAppStatusInstall];

  // For Existing user who has updated the app
  [[MoEngageSDKAnalytics sharedInstance]appStatus:MoEngageAppStatusUpdate];
  ```
</CodeGroup>
