StatTracker is an app designed to allow users to record their stats in various aspects of baseball. The app has three fields to record stats in: batting, fielding, and pitching. On the batting screen, you can record hits, walks, ball-in-play outs, strikeouts, singles, doubles, triples, and homeruns. The app calculates your batting average and slugging average from that information. On the fielding screen, you can record your putouts, assists, and errors, and thus calculate your fielding percentage. On the pitching screen you can keep pitch count, and record strikes, balls, strikeouts, walks, earned runs, hits, innings pitched. Thus, the app can calculate your ERA and K/BB ratio. The app is very useful and reliable for recording your baseball statistics.
