I am developing a news reader and the client wants to have a monthly subscription. It's easy enough, but he wants to have one month free trial for each user. Therefore, after the user downloads the application for the first time, he has one month of free use, and after this period he has to pay a monthly fee (automatic renewable subscription).
I was fixated on how to implement this. Any ideas? It is advisable without having to connect to my server and handle user registration and lawsuits from there.
Thanks!
