From The Church of Jesus Christ of Latter-day Saints:
Rather than maintain two Gospel Library apps, one for iPhone and one for iPad, we have decided to release just one universal app for both devices. Starting with version 2.3, we will no longer support this iPad only app. No future improvements will be made on this version and we will delete it from the App Store in a few months. Please backup your annotations to LDS.org using the Annotation Sync feature, delete this app and install the universal version.
