CAUTION!!! Please read before purchase!
I purchased this app to study for COMLEX Level II, and it was a great, high-yield resource. HOWEVER, my iPad later crashed and I had to get a new one. When I went to restore the app on my new iPad to prepare for COMLEX Level III the following year, I had to PURCHASE THE APP AGAIN for the full price (around $40) because they had removed the 4th edition I had purchased and replaced it with the 5th edition!!!!! I contacted the Apple Store, and they could not refund me, but suggested I contact Expanded Apps. After contacting them, they completely denied that this was the case, saying I should be able to download it for free as long as I was using the same iCloud. BUT THEY ARE WRONG - if you lose your iPad or break it or update it, you will lose access to this very expensive app and have to purchase it again!!! I would never have purchased this app if I had known this was going to happen. Unfortunately, I also purchased several other Case Files apps during 3rd year including Internal Medicine, Surgery, and Pediatrics, which I also have lost access to since the editions were updated. How horrible that all that money I thought I was investing was technically stolen from me after my iPad crashed. Very very very bad business!! I will strive to let everyone know to buy the paper copies of Case Files rather than the app so this won't happen to them. It's a shame really!!!
