This is the only app I have found that allows you to stack multiple images and paint layers, with the ability to adjust transparency and re-touch each layer going back and forth from layer to layer. You can save your work and come back and still have access to all layers. I am a professional artist and have found most other painting and photo apps for mobile are way too limited- including the photoshop mobile ap, which youd thing would be the best one. Im upgrading to the full version of Art Studio now.
