D&D Reader app brings paper reference books to your tablet

As much as I've wanted digital copies of the Dungeons & Dragons Core Rule books, considering that you have to pay-to-unlock all content for D&D Beyond and that the average player already has purchased physical copies of 5th Edition rulebooks, it's starting to feel like the players are being nickel-and-dimed. 

If Wizards integrated Reader and Beyond—where I could buy the Player's Handbook in one and have access to it on the other service—this would definitely become a instant buy for me. Until then, I have the Fight Club app by Lion's Den and a hardcover copy of the rulebooks.
