Create iOS App to consume data

Create a clean, flat, minimalist iOS App to allow interactions with SharePoint 2010 & 2013. The app will query the relevant SharePoint API's (most likely over REST) and store the responses and date within the App. App flow: 1) User installs the iOS app 2) User is prompted to connect to SharePoint and enters the URL (could be on premise or hosted) 3) App validates that the URL is a valid SharePoint instance and prompts the user to enter credentials 4) UI consist of a slide-out navigation panel (User profile picture and name, news feed, messages). A user should see everything based on what a user should see in SharePoint based on their SharePoint permissions. 5) Main app consists of a list of sites, drilling down exposes lists, documents etc. The lists and document libraries should have a similar design to the current, minimalist task managers available (look at the design examples below). Features: Allow offline viewing Save credentials Allow and save multiple credentials so a user and switch between different SharePoint views within the app App must look amazing, sleek and minimalist App must be responsive and faster than the default browser experience Design examples for inspiration: [login to view URL] [login to view URL] This is a proof of concept which will lead to another project so good luck. Send me a design example of what you can do and maybe a live login example and you will most likely win this project. Due to time I won't be able to respond to generic bids - so prove you are interested. I'm looking for someone with superb design skills (see the design examples urls above), and who is also a SharePoint and web service expert. Thanks
