Gospel Library 3.0
Gospel Library is an app designed for the Church of Jesus Christ of Latter-day Saints. It allows users to access an entire library of content, from scriptures, to magazines, to lesson manuals, and talks by church leaders. v3.0 was a major overhaul of the existing app and designed for iOS 6 right before the change to iOS 7's new flat aesthetic.
When reading scriptures we needed a place to show all of the related footnotes. n the iPad in landscape we had enough room to show the content and footnotes (or other related content) side by side.
You could search the library for words or phrases. Search phrases are saved so that the user can come back and continue looking for something at a later time if needed. Unviewed results were shown with a blue background so the user could remember which options they had already searched.
