This App has the same requirements (towards the functions) as the app wishbone, but is completely different.
To be clear:
You will not work on a wishbone clone!
But you have to implement the same functions, web services, and communications for the client (iOS app) and servers (web services).
You also implement the server software on Amazon EC2.
This should be a dynamic scalable solution. The app and the web services should be designed from beginning to support many users.
Between 10^3 and 10^8 users, the system should be able to work with a growing client side and a dynamic scalable solution.
To imagine a better picture, please answer this question:
How much does it cost to build the iOS App Wishbone ([url removed, login to view] ) and the implementation of the needed web services?
