Customer Reviews

Much Improved

The dictionary itself is, of course, the best American language dictionary available. The problem had always been the shoddy app through which it was published. This new app is much improved, and worth the price for anyone who appreciates nuance, depth, and first rate usage notes.

Feature request: kill off the splash screen except when first installed. Move it to the About option for those who want to see it again. I thought Apples rules for developers prohibited splash screens anyway.

Truly American English Dictionary

Other dictionaries may do in many cases; but if you desire an American English dictionary, then look no further. Do lookup the history of the American Heritage Dictionary though, you will begin to see what I'm talking about. Compare for yourself, especially with American works like the Federalist Papers.

Great app!!

This app is great. One of the best dictionaries out there. Not only does it provide thorough explanations, but gives you examples (so you can get a sense how to use a word).
