App needs some work

Landscape view is not available on iPad. Also, not able to access half of what I can access on the desktop version. Books for example won't show up. Seems like the app isn't quite up to speed yet with what people will be expecting from it.

Developer Response ,

We have released fixes for both of these issues. Please update ClinicalKey to the most recent version to see these changes. Thank you for the feedback.

No books

Clinical key in itself is great, but the app doesn’t have access to the material (ie books). Looking at reviews, this apparently has been a problem in the past. Not a lot of confidence that this app is reliable or even useable. Bummer, it could be so great.

Won't load

This app worked well enough until a week or two ago. Now I just get the orange screen that says clinical key and the circular animation that indicates that it's loading. I restarted my phone and deleted the app and redownloaded it. It still doesn't work. Extremely frustrating.
