No help available
This works very well for anagrams, word building, and judging, but I have yet to figure out how the pattern mode works. There is no help available in the app, at least that I can find, and the "Zarf Support" link from this entry takes you to a page that links back to iTunes. No help there.
I would give this 5 stars if I could figure out all the functions.
