Prettify and a simple existing iPhone application

I have a simple Xamarin Forms-based Visual Studio 2015 project that contains one view, which is a simple custom list view that lists some simple financial data. When the application launches it asynchronously pulls some data from a remote server and displays it in the custom view. I need someone to take this simple app and prettify it. It looks very dull at the moment, just black and white. I can provide a logo that can be used as the basis of a watermark perhaps (and a color scheme), and as the loading page. I'd also like the user to be able to drag the screen down and that trigger a refresh of the data. I'd also like to see a better font choice. Pretty simple project that I hope someone with better graphical design skills than me can improve the look of considerably ;-)
