As of today. It is not possible to publish the "single app" in the store, but we have already some users selling subscriptions through their website. After the checkout and payment on your website, you would "unlock" the app for this customer by inviting him to the app. Only then would you have to buy a license for this private user.
We provide the possibility to get a branded version of the Open as App container app. This is a payed feature on top of the enterprise subscription (see more details here: Pricing & Packages). You will receive an IPA/APK from us. This app can be submitted in the store.
One thing that might be interesting for you - if there is only one app installed/created in your account, this app will open after clicking the Open as App icon on the home screen of your device.
Open as App Store
What we have planned for the future is our own market place where users can sell their apps. The buyers then pay to use a specific app (within the Open as App Container). This is the way we will make commercial projects possible for non-developers.
We have already taken the first steps here and tested, for example, how the purchase of an app could be handled within the Open as App (inApp Purchase).
At the same time, colleagues are developing the "profile page" on the web portal: https://www.openasapp.net/portal#!/profile/details This is where the "premium apps" can be presented later.
