Trippy, weird, and awesome – Draw Motion: Motion Picture Review

I'm not sure this app is useful. But it's way too much fun. Drawing on the parts that move is a cool concept, and this app creates some...interesting results. Why does this exist? Not sure. Am I glad it does? Oh yes. Update: bug! I recorded a video, drew some motion, and then it had an error exporting and deleted from the app, it's not in my photos either! And it does have camera and photos permissions on.
