Pretty good
One of the more professional looking English dictionary apps available.
What I like:
-Option to use recorded audio pronunciation (requires data).
-Bookmark and notes.
-Words of the day.
-"sounds like" search feature for misspelt words.
-Puzzle solver for your word games.
-Custom web search to link to other reference sites.
Things that could improve:
-Cloud sync my bookmark and notes (iCloud, Dropbox etc).
-UI needs an update
