Pretty good


UPDATE: I've gotten used to most of the user interface quirks so I'll give it an extra star. Good for finding words that aren't in other American dictionaries. I think it looks odd that the original word is included in the Thesaurus entries, but I suppose it saves storage to be able to link one entry to multiple words.

Original review from 6 yrs ago:

I find this app to be handy but with some shortcomings. I find the user interface a bit awkward - I wish the navigation arrows went between screens I've looked at and not just screens within a category (more like a web browser). The depth & detail are inconsistent across definitions (i.e. for different words or phrases) but generally good when the info is there. Some of the written pronunciations are dead wrong; in those cases the audio version is usually correct (and vice versa). The app is worth having but could be better.

Loyal Customer since 2008!!


Excellent tool I use regularly, both at work and home, to communicate more effectively and to better understand what I read. The product also strikes a good balance regarding memory management on the phone. The dictionary is typically adequate, but limited, when there is no cell phone connection. Therefore, the impact on the phone is minimal. Then, the lookup capabilities become extensive when a connection is present. I will install this product on every phone I purchase!

Very Useful App

I find myself going back to this app quite often, to check word meaning, even to get correct word pronunciation. The only drawback is that if you do not know the correct spelling for the word you are trying to find, you are out of luck as there is no spell-help within this program. What I wind up doing in that instance is to go to Google and type in the closest spelling I know an Google then comes up with the word correctly spelled.
