It helps with coordination
Was my handwriting a mess because I was doing it wrong? - Holding pen correctly on both hands. 👍. (I'm ambidextrous.) - Is the corner of my palm supposed to be touching the paper as I write? If so, this children's writing program screwed up. > If your palm hits the corner in here, it moves you forward or back a slide (letter). Then again, I don't have tiny hands. BTW, Mom thought that was the cutest question in the world. She confirmed that I was doing it correctly. Overall, this is a good app for children. But if you're older and looking to rehabilitate your hands you may want to keep searching.
