Very useful, but needs update

Good app, with an extensive collection of words, but I cannot scroll my favorite words anymore. This bug greatly diminishes the usefulness of this app. Also, a landscape view option would be helpful, though not as important as fixing the favorites scrolling problem.

Pronunciation Key Missing

This app has many good features. Short articles about words, meanings and origin are interesting and fun. I really miss having the IPA pronunciation key which used to be an option. Now we only have the audible.

Doesn’t function independent of the internet

Your dictionary is generally very helpful, but only when used under the umbrella of the internet.
I’m certain I have a paid version, and it was my understanding that it would also function as a stand-alone app, not dependent upon the internet. I am frequently working at remote locations, and am unable to use it in those situations.
As I recall, I “downloaded” the dictionary in the past, but to no avail.
When the internet is available, I can throw any word I want out there for spelling and definition just by doing a random internet search. However, I’d like something that is readily available when the internet is not.
I don’t mind upgrading or paying extra for such a feature, but I abhor the idea of needing a quick confirmation of (what is typically) a simple word or idiom only to be told an internet connection is required.
Please advise.
