Abhishek Kumar's Sketch N Draw application for android is extremely clever, even the free version. It's so much fun and all too easy to grab a few nic-nacs from around the house and get drawing — I love how organic using my finger as a pencil feels.
My only frustration is the lack of image resolution and, thus, print size. Even though my tablet is capable of far more, the application determines the file size ... I'm not sure if the developer is aiming this application at people who only wish to doodle or post to online social media, or doesn't understand the quality artists and designers require. Of course, the paid version may be different ... I'll have to download it.
