Since nobody answered and downvoted, all apps needs to be submitted to the App Store and be downloaded from there exclusively, and all payments, even subscriptions that are made through the app, needs to go through Apple. Some providers like Netflix and Spotify are deliberately not offering the option to subscribe through the iOS app to avoid paying the Apple tax currently at 30%, and for subscriptions I believe the cut is reduced if the user is subscribed for a certain period of time.
