Paycrave was a  iOS 7 mobile ap project created as a payment for local food trucks.   I created user flows using Visio and then sketched them out on paper to make sure that the process worked smoothly.  I then took to Balsamiq to create the wireframe for the app. The style guide and logo were provided.  I tried to keep the number of screens to as reasonable as possible.  For this project I used the following software:  Visio, Balsamiq, Illustrator and iOS 7 iphone kit.
