I just finished an android application that will only require you to sight in your 20 and 30 yard pins. With the camera on your android device simply point it at your sight, line up the 20 and 30 yard pin markers and set your 40, 50, and 60 yard pins! I got the idea from the Trophy Ridge Rect Bow Sight. Let me know your guy's thoughts on it and if there is any modifications or functionality that needs to be added. Thought this could help some people save some cash, arrow, and time. https://play.google.com/store/apps/d...tems.sighttune
