  • Forced review

    By xflyer
    Terrible constant pop-up asking for 5 stars. Doesn’t go away unless you review! Despite paying for App!
  • Great

    yes, this costs money, but you get what you pay for. This app is well worth it. As a native English speaker, I refer to this multiple times a week. My job is not writing, but I do write for in my work and read a lot. Most of the time, I’m looking up words that I come across as I read. I discover the multiple meanings and nuances to words that I didn’t know. Also, I use this app for finding out if I’m using a word correctly. I find that we Americans can use words incorrectly without knowing it, form bad habits. I understand that this is how a word’s meaning eventually morphs, but not always the case. I highly recommend this dictionary and app!
  • Improved but Kill the Splash Screen

    By ReaderGeek
    The dictionary content is, of course, the best American language dictionary available. The weakness had always been the shoddy app through which it was published. This new app is improved, and worth the shortcomings of the app for anyone who appreciates nuance, depth, and first rate usage notes of the underlying dictionary. Feature request: kill off the splash screen. This is an unnecessary delay to getting to content. An ‘About’ option on the main menu is a more appropriate place for this seldom needed information. A user is opening the dictionary for content, not to see the cover again. I thought Apple’s rules for developers prohibited splash screens anyway.
  • Crashes

    By Brian320fo
    I tried to update the database for the dictionary. Ever since then the app crashes as soon as I try to open it. Worthless. There has to be a better app for cheaper. Update: I deleted and reinstalled the app. Now it won’t work offline unless I pay for it again! Sorry, I won’t do it. It also constantly asks me to rate it 5 stars. Are you kidding me?
  • Best American dictionary ever!!!

    By Chickee
    I teach vocabulary at the collegiate level and have required my students to buy the hard copy of this dictionary for the past 30 years. Now I encourage them to buy the $19.99 digital app of the dictionary as it adds new features for looking up words while still retaining extensive word usage and etymology that American Heritage is known for. The only negative is that you have to rebuy it for each device — iPhone and iPad for example. Many people will be quite satisfied with the free version, but I find ads annoying and think $19.99 is a fair value for all you get. Go forth wordsmiths with confidence that you are in good hands!
  • Great app

    By Jackflash1212
    Worth the price. I am very happy with this dictionary.
  • Otherwise wonderful dictionary RUINED

    By very unhappy app buyer
    by constant nagging to rate it — every time you open it! Two stars. Then you learn, no thanks to the App Store description, that your iPad purchase can’t be used on iPhone (and vice versa) without a separate, full-price purchase for your other device. One star. Good thing there is no “0 stars” option, because this app deserves it based on ruining an otherwise go-to reference work. (I am VERY happy with my dead-tree version of the AHD.) HEY, American Heritage and MobiSystems, still glad you asked me to rate your app?!?
