Will let you see a fraction of the words in the actual dictionary

I have been a huge fan of AHD for a number of decades and downloaded this app, in hopes that it could offer features available in the print edition.
I do like the "Word of the day" feature, when it actually displays the word, but, as it is with the rest of this app, you will not often be able to see either the word or the definition. The app does not proceed to an actual definition when searching for a word; it will simply "suggest" the word it thinks you are wanting to see. There is no functionality beyond that.
This has been a very disappointing app, and especially to a devoted user of AHD, it is only a few steps above worthless. Very sad. I never wanted to consider a competitor's product, but may be forced to do so, including looking elsewhere for a desktop computer version. That product is well beyond worthless, and in fact can do literal damage to your computer (they offer downloads, but numerous disclaimers that protect them from liability, because their downloads are laden with viruses, which they acknowledge). Shame on you, producers of one of the best dictionaries of all time, for creating such poor products. I hope you will once again create a great dictionary, in an electronic version, but I have a distinct feeling that those days are gone.

Great dictionary, but a couple of UI omissions

I've long appreciated the scholarship that goes into the American Heritage Dictionary. The Usage Panel is a great way to examine the state of the language, though I do think it would be improved by the addition of some good corpus-based linguistics. Having that dictionary available on iOS devices is a great form factor and extremely convenient. (I'm also enough of a language geek to enjoy having the appendices containing Semitic and PIE roots -- fascinating reading!)

The app is generally pretty good, and offline access is great! There is, however, one really unfortunate omission, and this is the main thing preventing me from giving the app 5 stars. It's great to be able to browse the dictionary by tapping on words that appear in definitions--but it's really irritating not to have a "back" button! This is particularly true when I've jumped to another entry by mistake. (Swiping from the left just opens the menu, and I don't see an obvious control for this operation.)

Five Star Review

You are very far from five stars. You are nothing more than a desk top dictionary. You forget that you are competing with google and the free dictionary by Farlex. If I can’t spell a word correctly you are no help. Your history and usage of words is skimpy. You make me pay an exorbitant fee periodically to continue to use your app. You are slow sometimes and your request for a five star review every time I open your ap is annoying. Remember I paid as much to use your app as to purchase a hard bound dictionary. For the price I expected a fairly extensive history of words
