I have been a fan of this app. It has always been my first install app and it does not work on iPhone 6 or 6 Plus. End pieces lock in the middle of board not around the edges and standard pieces lock in wrong spots. Save your money for the moment and buy when you see a 2015 update if at all. iPad would rate 5 this hurts me to rate 2 when it should be one. Will rate 5 after if ever fix.
