Interface could use some work, but a very helpful app

Content is concise and well rounded with enough to satisfy before reaching for alternate sources if needed. I frequently compare entries with Taber’s for a quick overview, as the perspectives are different but mostly complement each other. MobiSystems could learn a bit from Unbound’s interface, particularly the branched entries without leaving the main definition, higher bitrate voiceover, expanded indices, and more illustrations (“illustrated” is a bit misleading). The word history is helpful when revisiting terms. Not a fan of the “homepage” starting point and find raising the keyboard twice to clear old entries to input new ones annoying. Overall, a good product that gets frequent if not daily use. Worth the price and then some.

MUCH BETTER NOW. Congrats Team.

The only app I ever need in my med school

I use this app in my med school in a daily basis. It is very rich in information and photos. Thank you for iPhone 6 Plus update!
** The only thing that I hope developer may fix someday is its search method. If you look up a combined word, eg; juvenile Diabetes, the same word will be shown in search results. However , when u click it, the root of the word will be displayed (in this case,diabetes) and you should look for you word manually through scrolling. Which sometimes can be really cumbersome. Interfering with the functionality of this app as u might use it while training and ever second count.
