As noted previously, this is a great way to study the scriptures or prepare talks. Cant imagine all the time that it took to put this collection together. It is very convenient to see what church authorities have said about a particular verse or set of verses.
In addition, it has additional material such as General Conference talks, all the way back to 1942! (The churchs official app Gospel Library only goes back to 1971). I just recently discovered the powerful search and advanced search options available within the app, which are very powerful to filter results to what you are looking for. Check them out! I cannot imagine why anyone remotely interested in studying he scriptures would not want to install this app. Highly recommended.
For those who are complaining that the app does not remember where you were when leaving the app, there is a way to get around this in the meantime - set a bookmark.
