E-Commerce Site & iOS App Design

I’m building a customer-facing e-commerce platform and would like its visual language carried seamlessly into a native iOS app. The website’s core is online sales, so please design intuitive flows for a full product catalog, secure payment processing, and a user-generated review section...
