⚠️
"The app sent all three outfielders out before filling Pitcher or Catcher. I had kids standing in the wrong spot at game time."
— Adam, T-ball head coach · The real-world incident that made us rebuild the fielding engine from scratch. BatterUp! now validates every assignment before generating a lineup. That never happens again.
The Problem

T-Ball is different.
Most apps don't know that.

Every child plays every inning — no bench, no substitutions. Managing that fairly and consistently with paper or a generic sports app is harder than it should be.

📄
Paper fails
A player doesn't show up. You rewrite the entire card on the field while ten six-year-olds wait.
📊
Spreadsheets don't travel
Not accessible on a phone in a dugout. Setup takes longer than the game itself.
⚾
Other apps don't get it
Built for competitive baseball. Bench players, substitutions, nine fixed positions. None of that applies to T-ball.
How It Works

Game day in four steps.

BatterUp! is designed to be completable in under two minutes at the field, on your phone, with the game about to start.

1
Build your roster
Add players once at the start of the season. Jersey number, name, bats and throws. Reorder with a tap to set batting order.
2
Mark today's absent players
Tap the absent checkbox for anyone not showing up. The app adjusts everything automatically.
3
Hit Generate
The engine assigns batting slots and fielding positions to every player every inning — fairly, automatically, and without putting outfielders where the pitcher should be.
4
Print & play
One tap prints a clean two-page lineup card. Page 1 is the batting order. Page 2 is the field diagram with every player's position marked.
Everything you need

Built for how T-ball
actually works.

Every feature exists because it solved a real problem that happened at a real game.

🔄
Fair batting rotation
The last batter of each inning becomes the first batter of the next. Every player gets equal time at every spot in the order.
🏟
Smart fielding engine
Validates every assignment before generating. Supports up to 20 positions. Hard-blocks impossible lineups before they reach your clipboard.
🖨
Print-ready lineup card
Two-page card prints at 100% scale with no manual adjustment. Page 1 is the batting lineup. Page 2 is the field diagram.
📍
Park & field library
Save every park and field you play at. Dugout sides, chore lists, and field numbers auto-fill when you select a location.
👥
Live Scan compliance
Track coach and parent Live Scan clearance status. Only cleared adults appear on the printed lineup card — a league requirement handled automatically.
📦
Backup & restore
Export your entire team as a .batterup archive file. Import it on any device, any browser. Your roster is never locked to one machine.
