Looking for a well-coded iOS app where customers can select a Tier subscription (1, 2, 3) and be billed the appropriate fee on a monthly basis ($10, $15, $20).
Billing must be via the in-app purchase.
Customers must be able to select options within each tier (Product A, B, C) and change on a monthly basis.
Customers must have an account where they can enter contact information and shipping details.
Must be able to prompt customers that they are about renew their subscription - do they want to change which product they would like this month.
Specific information will be revealed upon application.
