  • Excellent App

    By Kevdafons
    Very useful
  • Continuously crashes on startup

    By billmcfa
    It used to work, now won’t start at all.
  • Complete & accurate

    By Laura_CS
    Other online dictionaries provide meager definitions and even less etymology / word origin. I have apprecited the American Heritage Dictionary in book form since the early 1980s, and am very pleased to have ready-to-hand rlectronic access.
  • Nags constantly

    By Adam-4512
    Every time I launch this app, it nags me to rate it 5 stars. It’s very annoying to have to click through a dialog asking me to rate it every time I want to look up a word. I’ve even turned off the option in iOS to prompt for ratings, but it doesn’t respect that.
  • They make you buy a new edition every few years

    -1⭐️ for not transferring my favorite words to this new edition -1⭐️ for adding nothing useful -1⭐️ for “throwing the off switch” on the older edition
  • Better than the 80s

    By hermionepei
    The 21st century’s version is definitely better than the 1987’s. And I like the professor Prof. Steve Pinker. ;)
  • AHD

    Used it all my writing life. Hard copy on my desk.
  • Good, but...

    By fill in space
    Good, but get rid of annoying rating prompt.
  • Too expensive

    By ImpossibleLove
    It’s a great dictionary. But does it have to be so expensive?
  • Losing features, greed rules

    By musicnartblue
    I’ve enjoyed American Heritage dictionaries since the 80’s, but your Reagan-era greed has to stop. I bought your app a while back, but to blackmail me for $19.99 to get audio pronunciations back is unfortunate.
