The best of the best.

This is an essential app for anyone. Like the book version, the best resource of all resources is the Merriam Webster dictionary. Where the written pages end, the digital version continues and offers insight and knowledge to the reader like never before. Pronunciation, spelling, definition and etymology are available at a moments notice. Just use the microphone key and speak that word that is unsure you. Not correct in your pronunciation, the app will find that right word for you. Need to know synonyms and/or antonyms, Merriam Webster provides an easy link. Why would anyone not have this app? The Merriam Webster dictionary is indispensable.


This app doesn't always have the answers I'm looking for, and it is not unabridged (which it doesn't claim to be,) but luckily we live in the digital age and most of us have access to an Internet browser. I mostly use this app to look up words while I'm reading.
Overall, I would recommend this app to anyone who likes to quickly look up words, or just hates looking through a big old dictionary.

So much variety in one app

This app is so much more than a Dictionary. The etymology for each word definition clearly rivals oxford's copious references to the evolution of words; the word of the day is a fun way to challenge your mind on a daily basis; and there are several game varieties to play to keep your brain juices flowing
