There is some problems


The app in my opinion is okay like I bought this app is a quick and easy app that I can look up words. But in my opinion it was not good enough for the price I have to pay. I am not going to comment saying it bad without proves. For one in some English words like “lead” there are two ways of saying it but this app provided one way. And sometimes when I look at how it define a certain words it’s hard for me to understand. Like the app is pretty easy to use I can give it credit for that but it need to improve to be better.

Love the app but the icon is heinous


As another reviewer already noted, the icon reminds me so much of Bank of America that I get these two apps confused all the time. It would be great if they changed the icon design to something that is more clearly that of a dictionary app. Trivial it may be, but it bugs me!

That being said, the app is perfect in every other way. I love that it has corresponding Mac and iPhone apps and that they all sync with one another. Wikipedia integration is extremely handy as well. I have no issues other than the annoying icon on my homescreen. :(

Faster, more practical than other dictionary apps


I've been using this app for quite some time, after having tried other dictionary apps. I kept coming back to this app because it was faster, more practical and more versatile than the others. After reading some of the other reviews, frankly I am baffled as to some of the criticisms. This app is a great tool for writers of any kind.
