This is one of the single most useful resources Ive used as a medical student. Great design, well written content, excellent illustrations, simple and intuitive navigation. This has been a 5+ star app for a few years, but the app does not function on the iPad with iOS 8. I havent had any problems with it on my iPhone, but I prefer the bigger screen both for reading and the illustrations. Additionally, there is content at the developer website that has never been included in the app. Developers - Please update the app. If possible, add in an option for connecting to a US formulary to compliment the existing UK and German formularies.
