The main requirement was was to make app discovery inviting and fun and to increase user engagement. This was achieved by providing a clear focus on search, simplifying the overall experience and making the app visually compelling.
I lead usability studies before and during the design process to get a good understanding of peoples needs and to find roadblocks or show stoppers early on. I was able to use data from our previous iPhone app to see whether there are features than can be de-prioritized, such as watch-list or following other people. For the Android app, I made use of Android-specific UI components, such as using a bolder, more flat visual style and making sure that the app scales into all formats for various devices.
The reaction from users, developers and the press were outstanding and our overall rating in the App Store increased from 3 to 4 stars.
