"As apps go, only Enfour’s American Heritage® Dictionary stands out for its graphic appeal and functionality. Although I was pleased to have so much lexical firepower in such a compact form, I was annoyed at how poorly the other dictionaries present on the platform." (4 mice)

My go to Dictionary.
A few years back the developers had made a decision to stop supporting and updating this app, meaning eventually an update to the iSO would kill it. I don’t know how many people pushed back, I know I did. Hats off and thanks to the developers for re-thinking that decision.
Wow! Wish I Had Purchased This First
I saw the reviews on sound not working for some downloads. The sound works on every word I've tried so far, and I've sampled a few dozen words. This is the best dictionary/thesaurus I have owned since I took my original printed American Heritage dictionary to college in 1973.
I purchased Rogets II first, then an under $20 combo dictionary thesaurus, and a cheaper dictionary. They fell short because only the common words were in these. I needed more depth. I decided to take a chance on this combo before many reviews were in, and I am glad I did. There are words in here that the cheaper dictionaries don't offer--a lot of them. It is very convenient to have the thesaurus in the same app so that you don't have to leave one to go to the other. I write for a living, and I plan to use this great resource extensively. The larger type size helps me and my bifocals. Thanks.
If you download this on your iPhone, as I did, be patient because it take about 8 to 10 minutes. I had to keep my iPhone awake by sliding my finger over the screen several times during the download. When the blue bar stops, it will keep installing, so just let it continue. A reviewer on the stand-alone dictionary recommends buying through your desktop/laptop with iTunes because of the size. Live dangerously, use your iPhone, but be patient.
The Best So Far...
I have used both the "stand-alone" versions of the AHD4 and Roget's, as well as this integrated combo. Regarding content, I prefer the AHD4 over what I consider to be its primary competitor: Oxford. While any developer can "buy" content, it is the user interface delivered and the responsiveness of the developer that matters most. Here Enfour has excelled: the UI truly leverages the mobile platform; this is not an "e-book," and Enfour has consistently strived for "customer satisfaction" in my dealings with them. And, having used both the standalone version as well as the integrated Deluxe AHD4, I can report that I have had no problems with playing sound/pronounciation files, no "crashes" of the phone or any other major defects. Yes, there are changes I'd like to see (e.g., to the History "Edit" function), and a bug in the standalone version's integration (not the Deluxe) has been identified to the developer, but all-in-all, this app delivers. For content, UI, and speed/efficiency, the AHD4 Deluxe is as good as it gets, so far.
