Free version is useless – Paint App Lab - Drawing Pad and Sketch Art Review

This looks like a pretty good app but in the free version ads pop up every time you change to a different tool making the app really pretty useless and totally disrupting the flow of any kind of creativity. There are all sorts of paid for add-ons but first you must pay to get rid of the ads because you can't tell much about how it works at all with the constant interruption.
