This is the first painting app Ive seen on iOS that actually simulates real paint. You can brush it on, or squeeze it directly from a tube, and then push it around and blend it with brushes or a palette knife.
The UI is a little bit weird, but theres a built-in manual that explains all the gestures — be sure to check that out. The weirdest thing is trying to rename your files; you have to swipe left or right on a file (which usually means delete…not a good choice for an iOS app) to rename it.
