Customer Reviews

The app worths every penny I spent

I don't write reviews very often, but I feel guilty if I don't write something for this fantastic dictionary app. First of all, the speed is superb, opening in less than a second. Second, the design is well considered and very beautiful. The content is very comprehensive, and there is pronunciation which is very helpful for English learners. All in all, it's a great piece of work, or should I say craft.
