a little buggy, a bit slow... but! the effects are nice (and some i've found only in this app, of maybe 30 photo and art apps i've tried) and it saves at full resolution -- something many photoediting apps don't do. for me, that's important.
in particular, it has the best cartoon, edge, and emboss effects i've seen so far on i-device apps, and tho the slider responsiveness needs polishing, they add quite a bit to my art arsenal.
to use this app: load the photo (book type icon, far left), then hit what looks like a crop icon to un-gray the effects buttons. when you apply a preset, be sure to hit the blue arrow precisely, and you need to wait before the effect is applies (about 30 secs or so). making this faster would be good, but even as it is, i'm glad i got this. i got even better results than some the devs show here.
