I've created an Android Mobile App that allows you to draw lines over any chess game. It's a simple app that, when enabled, has an overlay where it intercepts the touches from point A to point B thus allowing the arrows to be drawn. You can give it a go, and tell me your feedback. https://play.google.com/store/apps/details?id=com.gr.chessarrows   submitted by   /u/george_raouf [link]   [comments]
