Ratings and reviews

I used the print version of the American Heritage Dictionary in college and liked it. The definitions were (and are) well worded, clear, and concise. I also love the ability to see the word origins and the deeper understanding that can be given when studying. I paid for the full version of the app and can use it offline, and the premium features I find well worth the price.

Since 1975, I've bought this most useful dictionary, several times, and in several of it's editions. My favorite Dictionary and the Word Roots are so valuable. 🔴 HOWEVER, I paid for the $19.99 version (50% off Sale @ $9.99) and only have access to the Free Version! That's a Rip-off because I used it on this phone for several months and it was okay.

While I don't mind ads, they pop-up too frequently in MobiSystems products like this one. Prompts to upgrade to premium are just as intrusive. (I'll never upgrade because I hate MobiSystems). Definitions are slow to load making me wonder if that is intentional to compel users to upgrade. (Webster's loading seems faster). I am alarmed that replies from MobiSystem pertaining to negative reviews seem canned and therefore disingenuous. Audio pronunciation requires upgrade. No concern for customers.
