Is it possible to download a restricted app from the App Store?

Question

iOS

Can I download an app for personal (limited) use from the App Store? For example, access to the application is distributed by invites. The application at startup shows only the authorization form. Without authorization, the functionality of the application is not available. Or, for example, a corporate application script. Is it possible to distribute such applications through the App Store? Provided that the developer account is for $99, and the application itself is free.

Answer 1

You are putting yourself in a box. You need an enterprise account

It costs a little more than a regular dev account, but it's just a trifle compared to the cost of a full-fledged development. At the same time, you are cut off from the app store, their draconian rules and reviews. What you want is what you do.
