title: How to implement a subscription in a mobile application (iOS / Android)?
body: <p>I want to develop an application (iOS / Android) in which the user will have access to certain content only by paying a monthly subscription.
  I have never come across this and now I don’t even quite understand where it is better to begin to approach this issue and what kind of implementation it will have.</p>
  
  <p>Now I imagine this as follows:
  The application will be inAppPurchase information about which will be sent to the server with a RESTful API on which I will store information about users and their subscriptions.</p>
