I have/had the pro version. I adore the drawing capabilities - the painting is top notch compared to other apps (and I have pretty much all of them). So why the low review? Sadly the bugs. Palm rejection has serious issues, leaving small dots all over the side of your drawings. And I kept losing brush strokes randomly. The dealbreaker was when I lost an entire layer in the middle of drawing a stroke (several minutes of work and hundreds of strokes gone in a flash) - no undo to get it back either. So for me, its unusable at this time. The app shows incredible promise, but I just cant use it for real work yet. I hope to try it again in the future though, as it has amazing painterly feeling better than most.
