Ratings and Reviews
I am content knowing that I got my moneys worth purchasing the full edition. Offline use and the learners edition are convenient features of this application as they allow you to expand your vocabulary anytime and anywhere. Highly recommended for purchase of the full edition.
Better than other well known publishers
Bought this after much frustration with the Oxford concise dictionary and thesaurus. This app does the job much better and left me wishing I’d purchased it in the first instance.
Great app, use it often
Works well and stays on my home screen because I use it all the time. I love all the features and extra dictionaries and thesaurus.
