Good content, bad outdated design

The app cost 55$, I have to have high expectations for the price. The contents of the book are good and handful for review. the search function is nice although it can be better. Now about what needs so much improvements. The resolution just fuzzy and ugly on my iPhone 6 plus (which unacceptable for such high price). The content orientation on the screen is bizarre, especially when a table appears, you scroll right and left on empty spaces just because a table filling in the middle.
For the price I expect high level design and ease of use, which already free apps like medscape already provide. In Summary, good book, lousy app design.
