Add To Cart - Supreme Store

Every Thursday Supreme ( a clothing store) releases new clothes. It is similar to nike in the demand aspect. Since everything sells out in seconds, I am looking for someone to develop an iOS application that has a keyword interface built in to the app. I want the user to be able to open the supreme shop within the app and it the shop to be refreshing. Therefore when 11 hits on a Thursday the user's keyword will match up with the item and automatically add it to their cart. I also want it to have an optional auto check out. I have example to explain this much better. Please message me if interested.
