Gave the app a shot because it states that you can receive free access. As soon as it indicated that that "free" access requires a subscription that costs money, I was out. That is literally fraud.
I'm even less impressed upon reading other reviews. The fact that the app has cost others hundreds of dollars, and THEY STILL COULD NOT GET THROUGH ONE BOOK is absolutely insane and disgusting to me. So glad I didn't take on the subscription! It was clearly designed by opportunistic vultures.
