  • Glad that I upgraded to the pro version.

    By Βελλεροφῶν
    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?

  • My review

    By DStarrose
    I am very happy with this app. It has been useful when I hear a word I’ve never heard before. It is a great app but I would like to know why there are words that cannot be found yet I have found them in your dictionary book? Is it something that will come on a future update? Other than that I love this app.
  • M-W App is indispensable!

    This is one of my favorite apps! I keep it open whenever I read Bible passages or political discourse. It helps me understand the content and become a smarter person. I love it!
