I've tried several different coloring apps, this was by far my favorite. However, I made the mistake of accidently updating it. I have avoided doing this because in the past it has always caused issues. This time was no different. Would only load to a black screen and then close itself. Tried another device, but everthing I've colored before is gone. This is the 3rd time I've had to start over. Not sure it's worth it when I know it's going to break again eventually.
