This is a good dictionary but the support and website are never current or very good. When ever I contact them after an upgrade change they are acknowledge that they need to update their website and promise they will do so soon but it just doesn't happen. Too bad because I am now committed to this app but I don't feel they are committed to it. Please Enfour Inc. - get behind your product with full and proper support. Several years of bookmarks lost and they blame it on Apple. Please learn to take responsibility and quit passing the buck. And they want another $12.95 to upgrade to version 5.

Comprehensive, univeral, and well supported with regular updates. Who would expect so much support for a dictionary? Good job!

This is the complete 7.5 lbs dictionary. AHD's authority and breadth are unmatched. The app itself is well designed, stable, universal and continually updated. I bought this when it was much more expensive and it was a steal then. It's a no brainer now. If you are a student, no matter the level of study, this should be on your phone or iPad.

It's working again. Thanks.

This new update 3.2 doesn't link me to my ODE&OTE anymore. Is this a bug? All previous versions worked fine with this functionality. Please fix this.

The most comprehensive one I've found so far, plus 64,000 words include audio pronunciation. Bit pricey.

I must say I have never received a faster customer support response from any company anywhere else (Great job Tracey!). I submitted an e-mail request to Enfour and within a minute or so, I got the reply back. That kind of support deserves 6 stars ... Anyone with sync problems, please read the Applications release notes in App Store or read the Enfour FAQ. I got my sync issue rectified the following way: 1. Deleted App from iPhone and iTunes Library 2. Rebooted my computer, started iTunes, rebooted iPhone, connected Phone in the sequence given. 2. Deauthorized the computer and re-authorized again 3. Downloaded the AHD4 again from App Store (it is free the second round) 4. Attempted the Sync Again and it worked fine. It took a long time to sync -- occassionally appearing to freeze up.

The latest version won't install on my iphone, required a hard reset, after a lot of work i have my iPhone working again. Will not reinstall this app ever

This review has been updated for version 2.0 ----------------- This is an excellent dictionary—yes, it's large and yes, it's expensive. If your needs don't require a top-notch reference with full detail of etymology and audio clips for pronunciation then get a tome more suited to your situation. I had previously given this app a 3-star review; this update adds a lot and makes the product much better, but the implementation suffers. First I'd like to say that the app does load faster—noticeably faster, the new index listings are welcome, and the link to Roget's is a great feature. Nicely done. In the following, portions from my v1.0 review are set in double hyphens ("--"). --1) It doesn't use the IPA for pronunciation; if it did this would be a four-star app. I hope that this is fixed soon-- Well this has been fixed—but it's a bittersweet change. Alas, IPA is only displayed in a pop-up window when the user taps on the displayed pronunciation (which is in AHD's format). Wouldn't it be better to allow the user to select the displayed pronunciation as a preference setting? (In addition, the pop-up window is titled "AHD4.html"—oops, the programmers forgot to actually name it!) Finally, there's no pronunciation key for IPA. --2) No support for tapping a word to go directly to its definition. Enfour could learn from Ultralingua in this respect-- Another bittersweet change. The good: one can now tap any word in a current definition to be taken to that (new) word's definition. The bad: want to tap on a word in the etymology box? Cant be done (OK, this is a minor point, but why not?). Looking for *good* visual feedback like in the Ultralingua apps? Nope—just a cold, grey box that briefly pops up (ditto for tapping on a headword to go to the thesaurus). I'd like to be able to tap any word on the screen and be presented with an appealing menu offering choices like "Definition", "Thesaurus" (or "Synonym"), & "Bookmark". (To exemplify the problem of not being able to tap a word in the etymology box consider the etymology given for PIANO: "Italian, short for pianoforte; see PIANOFORTE." Yet I can't easily get to "pianoforte" because it won't allow me to select it.) --3) The appendices don't have any way to bookmark one's progress or position. There is a lot of reading here, for many people it's too much for one sitting (especially since it doesn't support landscape mode and therefore the text is small). A good way to leave and return to the same place would be wel

This is an excellent application. The content is immense and high quality (includes Canadian/British spelling for those concerned), the interface is very easy to use and fast and I've had no stability issues. The price is high compared to other apps but its worth it if you want an easily accesible, high quality dictionary The update seamlessly integrated this with rogets, has more intradictionary word links and loads faster. Stellar app
