Museum Height - An app to easily hang art using the 57 inch rule

My whole life I've been winging it when hanging art and it always looked vaguely disappointing. After our last move I felt sure someone would have come up with a better system. Turns out they have, and it's called the "57 inch rule" or "museum height". Basically, hang your art at eye-level to the centerline of the art. This works really well, but doing the work of measuring where to put the nail is tedious. I was spending enough time on the calculations that I started avoiding doing it. My paintings and pictures were stacking up against the walls. So, I made an app that does all the hard work for you. It's free. It allows you to stack as many paintings as would conceivably fit on the wall. It takes into account spacing between paintings. Everything is stored in the URL so you can send it to a friend or partner who is helping you out. Your house is gonna look so much better. I hope you enjoy it.
