Trying out the latest version (1.6) of the Procreate painting app. They've done an amazing job with it, and I can't wait to try out the supported pressure sensitive stylus when it becomes available later in the year.
If you have an iPad and you want to try painting with it, I'd definitely recommend checking Procreate out. I've tried a lot of painting apps, and this one definitely wins in speed and features.
