Poor results.
The interface is bad, which helps to hide the poor results when searching for a word. For example, searching for more returns less, fewer, many, much, and then a handful of words describing Sir Thomas More. Granted, the app is free, and it doesnt crash; but you can find much better thesaurus apps than this for free.
