Radar:The Radar apps work based on pressing Start when the pitcher throw the pitch and Stop when the catcher catches it. The more precise you are at pressing the Start and Stop buttons, the more accurate the resulting speed will be. Each time you track a pitch through the radar, it will add to the pitchers pitch count. Pitch Counters:Each time you press Pitch, it adds to the pitch count. When you reach the Warning total (in Settings), the button will turn yellow and the phone will vibrate. When you reach the maximum total, the button turns red and continues to vibrate. The opposing pitcher pitch count, simply keeps track of the opposing pitchers pitch count. Tracking the speed of the pitches in the Radar module, will add to your pitcher and the opposing pitchers pitch counts.
