Very simple yet powerful! What I like most is being +Simple +Really free (No ads) +No suspicious permissions required. It is my daughter's favourite drawing app. She loads her worksheets to it (on her Samsung Galaxy Note 10.1) and uses the SPen to write  draw  and color then save them. I've two suggestions that may make it better: 1- Replace the Load menu entry with a toolbar icon (the same way like Save). 2- Enable Palm Rejection for Samsung Galaxy Note when the SPen is detached.
