Anagramma Pro

You can ask for little else than an app which is simple to use and which works.

Whilst this has a nice interface and the ability to define words with the iOS dictionary is a cute addition, it simply won't anagram multiple words. You can input multiple words, but the results are always single words (pending the input query resulting in a single-word anagram - else 'no results found'). Would be endlessly more useful were it to list all component words which result from the input letters. Until then, this is little more than a toy with very limited appeal.
