  • At the Ready

    By LeveeGuy
    The AH dictionary is available at any time to increase your knowledge of our glorious English language. I appreciate the derivation of many words as well as the available synonyms. Very easy to use. I've had hard copies of AHD from the first one issued. Worth the cost.
  • Could be better

    By Ptgesia
    Had the current developer simply included all the features from the previous developer, this would remain a superior product. Mobisystems is either unwilling or unable to include the word quiz component which was present in the previous software developer’s version. It stands to reason, the people willing to spend the money on this dictionary are word aficionados and as such appreciate the quiz feature.
  • Redesign

    By Ben in Iowa
    Just don’t like the redesign near as much as the old. Upon launching the screen choices are more about selling the app to other (rate the app and share with friends). Generally speaking I want my dictionary to be a dictionary. Not some social app.
  • Oil Great dictionary

    The ability to speak a word you don’t know how to spell is awesome but the navigation could use some work. Also the thesaurus doesn’t seem to work. Otherwise it is a great tool.
  • Ok

  • Good, not great

    By BigBiscuit
    Good, not great. Nominal, not remarkable. Soluble, not satisfying.
  • Nothing like It

    By Gray 1
    And now it is even batter. I have relied on American Heritage fir over 50 years. This App raises the bar.
  • AD

    By Dantesvino
    Absolutely the best!
  • Worth the while

    By Felizalentz
    This dictionary respects and reflects American usage, while also illuminating a window into how lots of words got to where they are now. I also enjoy the pronunciation and thesaurus features of this app.
  • Great!
