I have made changes to my App using Rkimball's App Builder but they don't seem to reflect on my iPhone even after refreshing the App, what can I do?

First of all, you need to save your app by clicking on "Save & Finish" button then try to close the app and reopen it, if the changes still not reflect then try to uninstalling the app and then install again, hopefully this will refresh your app. Following are Steps to Uninstall an App on iPhone Device

1. Press on the app icon for few seconds then you will be able to see a cross button on the app icon.
2. Click on the cross button to uninstall the app.
3. Go to app store.
4. Reinstall the app.
