Customer Reviews

Needs a lot of work... Pretty terrible.

The predictive search as you enter a word only works assuming you are spelling the word correctly. Other dictionary apps (including simple online ones) will guess what you're trying to spell and list suggestions. So essentially useless if you heard a difficult to spell word, and are trying to look it up... Often you have to type your best guess of the spelling into Google, who will list the correct spelling, at which point you can enter that into the Merriam-Webster app. Or more realistically, you just read the Google definition. Which ironically is generally better. Which brings me to the thesaurus... It's terrible. Obvious synonyms and antonyms will not be listed. The Google definition will usually have many more synonyms and antonyms. Overall, this app gets it's clock cleaned by a simple Google search, making it essentially pointless unless you are temporarily without an internet connection, and want to look something up...

Not for amateurs

If you love words, this is your app! I jump on for word of the day and find myself stuck in the app for much longer than I intended as I click on more words, listen to pronunciation and even play vocabulary games. In response to a negative review below- We all count on spell check from time to time, but maybe if more people used the dictionary they would be better spellers. Rookies use Google, wordsmiths use M-W! Keep the bar high guys. :)

Favorite app

Easy to use, love the audible pronunciation feature. Dictionary at my finger tips. My kids love to use it for definitions and pronunciation. It also includes synonyms which expands my vocabulary. I also enjoy the word of the day and the word games. It will occasionally not have the word I'm looking up (I read a lot of older literature) but I have only the free app version. Definitely an essential. Merriam Webster is the best one available.
