Customer Reviews

Must have app

Extremely handy, (I do a lot of writing) comprehensive, has audio pronunciations for both American / English speakers and easy to use. Love all of the examples of word usage. So much easier to use on mobile device than hardcover book when on the go! I use this almost daily.

Fantastic App

This is definitely my only dictionary app. It is reliable, stable (does not crash), gives a word of the day, article of the day, idiom of the day, this day in history, quote of the day, and I enjoy the word games like Match Up! All of these features are a fantastic way to improve one's vocabulary!

Great dictionary app

This is my go to dictionary. My favorite function of the app is the pronunciation by real person. It also has words in other languages such as French, which can be very handy. Would recommend it to anyone who's looking for a good dictionary app.
