VERDICT
There are plenty of good free dictionary apps available for the iPad, not to mention the iPad's own built-in dictionary, so why would you want to pay for one? Well, it really depends on what your needs are. If you just need a basic definition and few synonyms, then one of the free apps (such as (Dictionary.com), will probably suffice. But if you're looking for a tool which allows you to explore the meanings of words in greater depth, then Terminology is well worth your investment. One thing it doesn't do, however, is give any indication as to how the words are pronounced, which represents something of a disadvantage for learners of English.
