"Good, Plain, and Simple"
I've got a few drawing/art apps on my Kindle Fire 7.5 HDX. This one is very simple to use. I love the way the selections of drawing instruments are laid out. My only complaints: 1) the inability to change the saturation of the colors as one lays them down on the page; 2) the inability to change the fineness of the pens, markers, and pencils. But for simple doodles and drawing its fantastic and FREE. If these features are scheduled for updates in the future I'd be very excited. If not, I still like it and use it for simple doodling while I am in boring meetings, etc.
