Excellent Application

Absolutely excellent application and a staple for every iPhone I will ever own! I love the Offline Feature (something which is quite rare within dictionary apps) and how I can search up a word wherever I am. Twice as good as I'm using it to research new vocabulary which I can use in my GCSE English Language Exam next year.
Thank you!

Does what it says on the tin

Extremely useful app, that does exactly what u want in a dictionary. Also has thesaurus and pronunciations.... for free
Did i mention that you can download part of the reference, so that it works offline?
