Glitch caused me to lose $12


This app glitched when I was exploring the settings so I tried to double click the home button to reset the app, but when doing so it read my fingerprint and used it for a $12 in app purchase. I do not even know what I bought and I am not happy that poor design lead me to lose $12 to this app I was planning on deleting.



Very accurate

Great app! Easy and accurate.


My friend set it up at Golden Gate Park with the Varsity Boys Gateway High School Baseball team. They threw pitches for over half an hour and it picked up virtually every one. Ten kids lined up to test their throws and then kept getting back in line. Most kids threw in the 50s. The pitcher threw as high as 69mph. Even a girl from the stands came down and threw in the 40s. Then one kid on the team, who wasn't even a pitcher, threw a 78 mph ball. The kids gasped and thought it was a mistake - but then he threw them again and again. He had no idea he had such a great arm. The pitcher said, "you should try out! We need more pitchers!" The team was second in the league at the time. It makes you wonder how many other kids out there have hidden talent and don't even realize it! Not sure why the other reviewer had a problem. Just be sure no one moves during the pitch if they are standing in view of the device. At 10x cheaper than the least expensive radar out there - this is a great app!
