Customer Reviews


This is an absolutely outstanding app. Why in heavens name would you not allow this app to be used in LANDSCAPE VIEW!!!!! I just do not understand why developers make apps like this without that feature!

I have had almost every dictionary available in the App Store. From the New Oxford dictionary that was, upon original development, a $40 app, to basic apps that do pretty much nothing. I've found this app to be one of the nicest, more user friendly apps of all I've used, including the New Oxford app.

In fact I got this app because the New Oxford app decided to change their app and removed the listen/voice feature and now requires an IAP if you want to hear the word spoken, even for those who had already purchased it. And the older app is no longer available, so in order to update you must update to the new version which has a new name. You can no longer download the original app purchased.

So, needless to say, I needed an app which provided all of those features. This app does just that and then some! By the lack of landscape view completely alters my rating on this app! There is nothing more frustrating, when using tablets, than having to constantly rotate the device because developers fail to make apps compatible with all devices. Especially apps this!

Just my 2¢.

My Reading BFF

I use this app everyday. I got tired of assuming the definition of words based on the context it's written in, and now I can find the exact definition, instantly. I love that it keeps a history of words you've looked up and that it's completely accessible offline. I wish it had a thesaurus, but it does suggest words that have a similar definition to the word you searched for. Special thanks to the developers for steadily releasing updates since I first bought this app in 2008!

Success From Words

Great Dictionary, & being a writer for Education means I need a trusty dictionary friend by my side every single day, for as any writer worth their grains of salt will admit, maybe the single greatest tool in turning into a better & finer writer is: READING, & for me at least that means reading voraciously the best sellers& in many fields too. The need of a great dictionary like this one therefore, can never be underestimated. I thank you, my imagination thanks you, & my Soul also thanks you ever so kindly. And my words thank thee...
