  • Great App

    By Retro Suzy
    While the app could do a little better at speech recognition it is so very superior to going to my 20 pound dictionary. Being able to correctly interject my thoughts in a conversation proves invaluable. Language is such an art and to articulate concepts and intent requires that it be guarded and fostered. This app aides in that pursuit. An improvement would be to offer the content of the ALL previous editions. Many words have fallen into antiquity merely due to their lack of exposure. I would gladly pay for this feature.

    By Den John71
    I enjoy reading Christian books and stories. They often use words that have no meaning to me. This app gives me all and total explanations of just about every word I look up. Thank you so much.
  • Love the quizzes

    Great way to pass the time rather than social medicating, and I like being able to save favorite words. The pronunciation has come from n very handy too.

    By Kingreggy
    I love the app, just that I don’t get an alert of the word for the day, I have to manually go into the app for that, aside that others are perfect.
  • Absolutely Indispensable!

    By MeginProv
    I rely on this app multiple times per day, especially when writing or editing. Easy to use and contains an extraordinary amount of accurate, detailed information. I particularly like how easy it is to move from definitions to a thesaurus-worthy list of synonyms. I recommend this app without reservation.
