Working together with a developer, I created the Top Tile app to work on multiple iOS platforms. I headed all of the user experience and designed all of the graphics while actively participating in the usability testing process. 

​

We started the process with a story board followed by low fidelity wireframes. Once the layouts of the screens were finalized we moved on to high fidelity designs, which we later turned into the final product.

​

Even though Top Tile Contest is currently available in the App Store, we continue to test the app with our end users and collect feedback for future enhancements.
