  • Favorite words disappear

    By dw66
    I like to save words to review the definitions later, and there is a place in this app to save words: “favorites”. However, the list seems to get deleted for no reason every now and then. The Webster app does not do this. I prefer the American heritage dictionary over Webster but the disappearing favorite words is a dealbreaker.
  • Dégeulasse

    By brebisaupâturage
    The AHD is an excellent dictionary, I own the hard copy, but their digital version could definitely be better. I absolutely hate the color scheme; its bland and does not give the sense of using a scholarly ressource. They could definitely add hyperlinks for the words. I would have more to say but this review was on-the-fly prompted by the incessant pop-up begging for me to review the app. To the developers of this $20 app: would suggest reviewing the $6 app dictionary “le petit Robert” made by the french (c’mon ‘merica). It is superior in every way; please learn from them. If the production of this dictionary app was as good as “le petit Robert” I would happily pay $50 for it.
  • No word of the day — PLEASE!

    By Rudy_Chasal
    As long as this and other dictionaries continue to issue the aggravating word of the day, I’ll stop using them, which means I’m deleting the app despite my having spent money on it.
  • HMS Beagle

    By Origin of Species
    The best dictionary supported by this EXCELLENT app!
  • Annoying begging for 5-star review

    By Galena Guy
    Too often, when opened this app presents a pop-up that says, “Enjoying this dictionary? Please support us with your 5-star rating on App Store!” with a “RATE 5 STARS” button underneath. The only way to escape -- to do what you opened the app to do, use the dictionary -- is to tap the small “X” close icon at the upper right of the pop-up. Having done that, one has the startup page, which contains a “Rate Our App” section inviting a rating, with 5 blank stars underneath as if you could tap any of them. But if you tap any of them, the result is the same obnoxious “5 STARS” pop-up. This scheme annoyed me enough to motivate me to take the time to create this 1-star review.
  • American Heritage

    By Mother and Homeschool Teacher
    I love the American Heritage dictionary program. I have and it doesn't even compare to the American Heritage. The word of the day from is always a word never used or heard of. American Heritage so far is 100 times better in every way!
  • Great dictionary, but...

    By John Weeks
    Super annoying how often it asks you give it a 5 start rating.
  • Good Helpful

    By Zed Iye
    It serves my purpose well. Very helpful.
  • Disappointing Implementation

    By Erik Steinmetz
    I love the AH dictionary and have many copies in paper and electronically. This implementation, though it contains all the content, is disappointing from a user interface perspective. The pestering dialog to rate the app (apparently only as five stars) never gives up even after you have declined to do so many times over years of use. The limited choice of color themes (only four) are all too bright, disallowing any subdued choices. The navigation design is especially poor in the special portions such as trying to browse the appendices or looking through the index of tables: the upper-left back button alternatively brings you back to the location from which you arrived (correct) or simply the item listed immediately before the one you’re currently looking at (incorrect). I hope that this developer can start paying attention to details, or that AH passes its app along to someone else (for which I would happily pay again given this app’s shortcomings)
  • Really a great dictionary

    By Rosewreath
    But annoying that it keeps asking me to rate. Turn this feature off!
