François Guerin is a French UI designer, art director and digital artist who likes to paint and sketch on his mobile devices, using Brushes for iPhone and Procreate for iPad.
You can see his work in his Flickr set, a smaller set on Coroflot and prints on society6.

His art has a crisp cleanliness, along with a loose gestureness to it that I think gives it an almost “familiar” feel.
