Ratings and Reviews
Great for studies
Amazing if you don’t understand words
This is awesome
I'm a dj on a radio station. I present the afternoon drive. This app is so much of a big help that I find myself asking my audience about the meanings of some words, having them call and explain them. It's a lot of fun!
Wonderful and useful app
This app is convenient as much as it is useful. Fast searches and the daily words helps to expand ones knowledge base
