  • Stop the begging

    By B. Professional
    Really tired of being begged fo a five-star review. If I wanted personal opinions I would consult a creditable source like MySpace.
  • Audio issues

    By distribution clerk
    Love the app but the volume for pronunciation doesn’t wrk; kind of defeats the whole purpose of learning new words
  • Excellent, but not as good a the OED

    By Johnchik
  • Best Dictionary I’ve Used, but . . .

    By Eric from Austin
    Good etymologies and helpful usage notes. Also has easy-to-understand pronunciations and audio pronunciations if you’re still not sure. Unfortunately, trying to get a redemption code so that my husband could use the app on his new phone took over a month.
  • Good content, frustrating ratings pop-up

    By (AD)
    The dictionary content is great, but the app repeatedly interrupts use with a pop-up asking for a five-star rating. There doesn’t seem to be any way to stop this from happening.
  • The printed version is better

    By Columbia03042
    I am use to extensive usage notes as in the printed version. I wish this app mirrored it more completely. This was my favorite dictionary. It seems like it is its competitors and not longer the standard.
  • Love these Indo-European roots!

    By Billykershaw
    I am thrilled almost every day by this dictionary. The definitions are thorough, the word origins are as good or better than most, and the Indo-European (and Semitic) roots are an unexpected and wonderful surprise. Congratulations, American Heritage!
  • Indispensable

    By TSoules
    But those idiotically grinning stars that suddenly position themselves in front of one’s search, and their moronically cheerful How do you like us? Are almost enough to make me look elsewhere for a lexicon. Such a loathsome intrusion.
  • Excellent

    By Mike2663
    If I can limit your vocabulary, I can limit you intelligence and your knowledge & understanding. Enough said? Buy and use this App. It is a bargain!!!
