I will look about for iphone apps, but Inspire is the nearest thing I have found. You can choose either a loaded or dry brush, and if loaded, you can choose how much paint is loaded, and whether the brush then reloads automatically or runs out. After it runs out, you can go back and smear the colour to blend it. But I have to admit it doesn’t run like the watercolour brushes in Corel Painter.

What I really want is a true watercolor app that will let me choose not only the pigment, but also the amount of water, and will have those effects only watercolor is famous for: bleeding out textures as it soaks into the paper.

There’s an online Flash version called Farbe, made from Pixel Bender software that’s exactly what I want, but for the life of me, I cannot find an app that does this. Let me know if you run into any art app that does this; I’m wasting way too much time trying to hunt one down.
