If you thought you could replace that bulky volume with a convenient app, dont waste your money (or ditch the hard copy, like I did). Im not even sure that the app is posted on the app store, which would mercifully save some other unsuspecting buyers from this fraud. For example, type in a biblical quote, such as "how have the mighty fallen." A one sentence quote is referenced to "the Holy Bible." Period. No book, chapter, line citation that would allow you to expand the quote, put it in context, or even find it in the original source. This is worse than useless; it is blatent rip off.
