I hardly use it anymore because it always crashes. When you select a landing spot the magnifying glass doesn’t work all the time, sometimes it’s ball tracking is awful and nowhere close, when you try to edit ball flight manually if you touch the screen it completely ruins the ball track and you have to start over, and it crashes when you try to save the completed video (all that work for nothing). There has hardly been an updated version that hasn’t had major problems for me. I use an iPhone 5s. Your mileage may vary, but I’ve been extremely disappointed. I should note that when it does work, it’s a very cool product. Good luck!
