At team practice I set up my iphone 5 on the side of the court and game linked it with my iPad 2 in the basket next to me. We hit ball after ball and the app picked up almost every single serve. It read anywhere from 60-101 mph depending on who hit. After ten minutes we had practically the whole team involved either competing or calling out speeds. It was awesome and the competition was fierce! Super easy and fast set up. Loved being able to tweak my serve and know it made a difference. Great app. Totally worth it. Cant wait to see what I hit next time!!
