App Needs Serious Work

The resources on clinical key are great, but the implementation on this app is awful. There are basic features missing, such as a “find on page” function that even the stock Microsoft Notepad has. Users also cannot add books to a library or favorites list, so to access the same book at a later time you just have to search again for the book.

App needs serious work

This is rating app usability not the content

UTD app >>>>CK app

If CK wants to compete with big brother UTD

- stop logging me out each time I minimize
-have a save login feature easily accessible
-landscape mode on iPhone with less screen overlap bug
- favorite book saving option
-options on screen color and text size please
- cleaner experience that is less laggy
-option for DL of material would no network is needed

Please do this. For a grand a year for the IM packet we should have a more functional app since it is almost 2020.

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.
