As of January 25, 2016, stay away from this app and use the internet to look up words instead!
First, this dictionary app does not contain simple terms such as "contronym," "contranym," "autoantonym," nor "pnigos."
Secondly, this app does not have any audio capabilities.
Worst buy possible and this app disgraces the Oxford "good" name.
