Fits my needs great - & quite useful!


I've been using this app & another (big-name) dictionary both for a while; not daily, but as needed. I've enjoyed that I don't have to be online to use it, and I've loved for some unfamiliar words, how the Advanced English Dictionary also can give some history of the meaning(s) on the word.

Recently, that other dictionary slipped in ads (not very subtle ones, either), &I went from free to charging to get back the ease of use that I expect in my apps. That one is now *gone*, and this AED app is my undisputed king of my dictionary apps. AED is an excellent dictionary app!

Excellent use everyday


This will blow your mind being able to look up every word smoothly and read the word origins broadens and sharpens the mind. I love looking up even seemingly normal words but then gain benefit from knowing EXACTLY what it means.

Only problem with this app is the going back UI. Totally loses my previously typed words, it seems like the straight disappear. I want to go back directly, not get restarted on a brand new search. Fix that. And a dropdown of previous lookups that can be cleared one by one manually would make it way better.

I also recommend their other app World Factbook which is totally updated and brings nothin' but the cold hard numbers of every country. It rocks. Just try reading the entire USA one and tell me you didn't learn one single thing. No way.

Ok cheers buy it now it's a lifer.

Excellent Reference Source-Highly Recommended!


In that I read and write quite a bit, the use of a dictionary, thesaurus and finding proper antonyms and synonyms is a must. It is difficult to find the definitions of and use of words that are either rarely or no longer in use. The Advanced English Dictionary & Thesaurus fulfills this need in my endeavors. I most highly recommend this reference source.
