Before switching to Android, I was an iPhone user and used Clay Tracker to track my sporting clay scores. When I switched to Android, I was surprised to find out the Clay Tracker app was not designed for the Android Platform. I searched around and thought I would try this App. It was the same price as Clay Tracker so I was expecting it to be on par with Clay Tracker. I was very disappointed once I got it downloaded and opened it up. Unlike Clay Tracker, this app is not flexible at all. I almost always shoot on 100 round courses. This app won't even let you modify the count to match up to a 100 round 14 station course. Luckily I was able to get a refund since I immediately returned it. Since I haven't found a good clay score tracking app, I will buy an ipod touch and continue to use Clay Tracker.
