There are two ways to use Ionic View. You can either upload your own app or load someone else's app ID. If you test your own app, follow these steps:

1. Download Ionic View from either the App Store or Google Play.

2. Make sure to register an account on ionic.io.
3. Go to your app's project folder.
4. Search for the Ionic upload.
5. Enter your credentials.
6. The CLI will upload the entire app and give you the app ID, which is 152909f7 in this case. You may want to keep this app ID to share with other testers later.
   
7. Open the Ionic View app on the mobile device and log in if you haven't done so already.
8. Now, you should be able to see the app name on your MY APPS page. Go ahead and select the app name (myApp in this case), as illustrated:
   

9. Select VIEW APP to run the app, as shown:
   

10. You will see that the app interface appears with initial instructions on how to exit the app. Since your app will cover the full screen of Ionic View, you need to swipe down using three fingers, as illustrated, to exit back to Ionic View:

If there is no code update, the process is the same, except that you need to select SYNC TO LATEST from the menu.
