If you want to use this only as a rhyming dictionary, its okay and seems to do a decent job. But its also supposed to be good for writing lyrics, poems, etc. You can (once the on-screen keyboard works - didnt for the first little while on my iPad) but once youve written something, you have to retype it in another app or on a desktop (or even on paper) if you want to use it anywhere else. Except twitter. You can create rhyming tweets. Very useful (not.)
