About this app
ABS Challenge turns baseball's Automated Ball-Strike system into a game of judgment. Watch each pitch from a broadcast-style home-plate view, then decide: was the umpire's call right? If you think it's wrong, double-tap to challenge. An ABS-style replay zooms into a 3D strike zone and measures the ball's distance from the edge in inches — confirming or overturning the call. • Pitch it yourself — flick to throw, re-grip the seams to pick the pitch type • Track real velocity (mph) and spin (rpm) on the stadium board • 9 innings, 27 outs — read it right or take an out • Game Center leaderboards: Top Speed, Top Spin, Best Score, Best Accuracy • Name the two teams and pick their colors • No ads, no tracking, no accounts — just baseball Trust your eyes. Make the call.
