This app is similar to another painting app called Paper. It has many features in common and a similar basic user interface. However I have found several bugs which I can’t understand how to fix. When using the text tool I can add text to my drawing but I can’t find a way to exit the text tool and go back to the main toolbar. I have to force quit the app and restart it to continue drawing. Another issue is that sometimes when drawing close to the side, the app does not update with my brushstrokes at the edge of the screen until I try to zoom in or out. Once these issues are fixed, I would rate this app 4 stars.
