Stellar reference, unpleasant interface

The candy colored user interface of this dictionary app and its annoyingly frequent review requests of late gravely detract from the otherwise stellar content. The only reason to have this app is for convenience of access, supplementing the iOS built-in dictionaries, which are of equal caliber. It is sad to see such a quality resource get tarnished by bargain-basement behavior.

The definitions are authoritative, and are based on the same corpus as the full OED. I especially like the etymologies and the articles foregoing abbreviations. The latter is unnecessary for digital editions but too often lazily carries over from print editions by other dictionary publishers.

Great dictionary - clear and helpful explanation with etymology

I have this Oxford American Dictionary on both my iPad and Macbook Pro. The dictionary came with the Macbook Pro when I got the laptop. The explanations in the iPad version are the same as those on the laptop. They are really straightfoward and easy to understand, much better the Webster dictioanry as the Webster sometimes only gives you a synonym as definition instead of a clear explanation.

The etymology (origin) section of this Oxford American Dictionary also helps tremendously, since you get to know how many English words are composed, where they come from. This makes remembering new words much easier. Many dictionaries do not have etymology notes to their words.

Although the iPad version costs you some money, it’s money well spent.

I love this dictionary

The dictionary itself is stellar. There is no better English language dictionary. It is a prescriptive dictionary, which means it tells you what words mean, not how they have been used lately. It's what people expect from a dictionary, but most are not like this.

The app itself is pretty good. It could use some interface tweaks like a Back button, but overall it works well, if not flawlessly. The biggest irritation is the continual requests for five-star reviews.
