I need a basic iOS app

* my client runs a service that provides tips / advice (buy/sell instructions)

* my client is interested in a simple Apple app that can be marketed on the Apple Store

* the app needs to have the following functionality:

a) free trial that becomes a subscription service
- upon downloading the app, the users has a free 7 trial
- this automatically becomes a subscription service, unless the user unsubscribes before the end of the trial
- this is a feature that Apple offers developers, as a way to monetise traffic (see the following link https://developer.apple.com/app-store/subscriptions/ )

b) data capture
- once the user has downloaded the email, they will be greeted with a pop-up box that they have to press OK to start the free trial
- having pressed OK to the terms they will then enter their Apple ID password and the trial will start
- thereafter the user will be presented with another pop-up box that will ask for certain personal information to be supplier (e.g. Name and contact number)
- to keep things very simple, this information is to be forwarded directly to the client, not stored in the app

c) running the service
- my client wants to be able to notify the users when they need to access the app for information
- provided they are either on the free trial or have not unsubscribed, the user will go to a Members Area of the app where they will find information supplied by the client
- my client needs to be able to update the Members Area with information. Again to keep things simple initially, there is no need to keep a record within the app of updates to the Members Area

Should this first step prove successful, we would be looking to roll this model out to other platforms (Android etc). Furthermore if you are able to provide a cost effective solution initially there will be plenty of scope in the future to add further functionality overtime as the app picks up traffic and we can see this initial investment was worthwhile.
