Form creation/management tool for iOS with web backend

I have already made the wire-frame for a form creator for the iPhone. This back end will need to be able to be backed up with AWS as well as work with a future android app as well. Please be familiar with [login to view URL] Please tell me how you could make jot form service a iOS app including a monthly subscription model not through apple. This explain the project and your response will tell me if you read this or are sending me a form fill. I have features needed, but many I own code that already has the needed features to add. You need PHP, REST, Xcode knowledge.
