App with membership

My client has a requirement for an app. iOS and Android.
The app will be fairly basic, with a requirement to display just specific textual information when the subject header is selected.
The app needs to have a monthly subscription to it, without which, the information is not available - so no offline content. There is no requirement for the app to be used outside of data coverage.
Concept is a main menu with a selection of headings. When selected, it displays the information on that heading - rather like selecting a record card and seeing it.
Please also quote for registering the app with app stores and moving it to hosting.
