Customer Reviews


This dictionary is well worth the price tag. The definitions aren't super extensive in my opinion, but I have been able to find virtually every word I've looked up so far. So it's great if you want to find out what that word means, but not always the best if you want to get specific about how to use a word, or which word you can use among synonyms (do braggart, boaster, bragger, and vaunter really all mean *exactly* the same thing?). The etymology is a HUGE plus, too, as are the web links for when you feel the need to go off road! Plus it is quite stable and straightforward.


I love to read and I like words. So looking up words as I read BUT I also study vocabulary so to enhance my knowledge and readying comprehension. Your app is simply the best for my needs. My only recommendation is to add languages. E.g. I look up word "A" per say and I can get the definition in say, English but have the settings to provide that word in Danish or whatever language(s) I set This way I learn the definition and know how to say/use it in 2 or however many languages I chose - expanding my knowledge on several languages at a time. Thanks again!!

My favorite app!

I love the audio pronunciation for each and every word. The real voice recorded by Susan Barnes is the best among three voices in the application. The feature to tap on any text in definitions, in word links, in the thesaurus and even in etymology or in other web integrated dictionaries is the most outstanding of this dictionary. Everything is just a tap away .
