Ball or strike? You make the call.
Ump Eye puts you right behind the plate for the toughest job in baseball: judging the pitch. Watch it leave the pitcher's hand, track it all the way to the zone, and call it before the clock runs out — no sound, no help, just your eye. Then find out exactly how right (or how wrong) you were, down to the inch.
It's simple to pick up and surprisingly hard to master, which makes it fun for a curious 8-year-old and a lifelong baseball fan alike.
HOW TO PLAY
Every pitch arrives with real velocity, spin, and break — fastballs, curveballs, sliders, knuckleballs, and more. Call "Ball" or "Strike" before time runs out, then watch the zone light up with the verdict and the exact margin. Every miss becomes a lesson.
FEATURES
Three difficulty levels, from generous straight pitches to nasty, borderline-everything sliders
Two rulebooks: the classic strike zone, or the 2026 Automated Ball-Strike (ABS) zone
Cinematic instant replay: a broadcast-style 3D flythrough that circles the exact spot the ball crossed the plate
Look around: switch between the umpire's view, high home, either baseline, or straight from the pitcher's eye
Drill Mode: practice the exact corner of the zone you're calling worst
Daily Challenge: the same 15 pitches for every player, every day — compare your streak with everyone else's
Versus: challenge a friend to call the same live pitch sequence and see who's the better ump
Full session history: accuracy trends, a heat map of every call you've made, and whether you're squeezing pitchers or hitters
Adjustable decision timer and strictness, so beginners and veterans both get a fair, honest test
No login, no account, no data to hand over — just open it and start calling pitches. Session history stays on your device.
Whether you're a Little League parent who wants to actually understand a close play, a player working on your batting eye, or someone who just yells at the TV every time a call looks blown — Ump Eye finally lets you find out if you'd have gotten it right.
Step behind the plate. You make the call.
