I love the American Heritage Dictionary! I have the $60 edition and the hardcover portable one. Those are NOT digital! Actually, I have a subscription to "The Failing" New York Times and I do NOT use the digital version! On the go, I carry the portable AHD with me everyday! I write poetry and it is extremely useful for my purposes in writing poetry! I just wish there was no additional cost of $19.99 for an enhanced version? I cannot afford it. ☹️. Best American dictionary BAR-NONE!

It's an okay dictionary app but is not fully functional. It's word of the day feature is usually a phrase and not a single word. It has a difficult time giving definitions for spoken words.

AHD app adequately fits my needs because it has huge number of entries that are defined with words that fits the curiousity of intermediate to advanced English readers/learners. Second, you can easily increase the size of the words with your two fingers, which is an important feature for readers with vision difficulties. I love the AHD and I use it almost daily. Thank you.
