Welcome to the community.
When using App Inventor for ios, most users, except for a small test group, cannot install an app on an iphone. MIT has not yet released the compiler for general App Inventor users.
Sorry, unless you are a member of the test group, you cannot install your ios app. You can probably install a version of your app on an Android phone.
