  • My go-to app

    By Joe Dictionary
    I have several dictionary apps, which I use to compare definitions, and when one of them doesn’t have a definition I am looking for. This app is my favorite.
  • Continuous improvement and beautiful interface

    By Janjamsocool
    I love this app! Perfect for people who strives to improve their English :)
  • Is there anything better?

    By Frankdog51
    MW is ok. I subscribe because I can not find anything any better. Lacks root info. Lacks any real comparison with similar words. It is a stripped to the dusty skeleton of what a good MW print edition offers. Of course, a full feature dictionary might be found in a used bookstore. But good luck in your search for this store.
  • Glad that I upgraded to the pro version.

    By Bellerophōn
    The free version works fine and very well, only the ads’ constantly popping up sometimes compromised the experience. The pro version is totally worthy of the money and game changing. One small question: What’s the difference between the pro version and free version with subscription?
  • Great app

    By Dr. KQR
    Good for refreshing vocabulary on a daily basis at a fingertip distance while passing time.
  • Great resource

    By Leilert

    I’ve been using scores of dictionaries for decades. This is outstanding. Easy to find meanings, synonyms and antonyms. Buy it!
  • ALMOST the Best!

    By Solesister_3
    This is my go-to app for defining as well as thesaurus. Very rarely will it not have the word I'm searching for, maybe 1 out of 50. 4 of 5 stars = need a back arrow while viewing related words. This would be a large benefit in returning to the previous definition without returning to the opening screen to start over.
