On the one hand, I love it. Great idea. Good poems. Fun and inspiring.
But poems have their own mnemonics built in (rhyme, line breaks, stanza unity, alliteration, etc.), and the app doesnt take advantage of them.
It especially irks me that sonnets are simply split in half, not divided logically into 4/4/6 lines.
Oh, well. Still great fun.
