✓Full-screen Game Mode with large text and max contrast

Game day features

Less chaos in the dugout

Six43 was built to be useful when the game is actually happening — not just in the planning phase.

🔒
Locked view
Once the game starts, lock the lineup. Position assignments are protected against accidental taps — but the score is always editable. One tap on the lock icon to unlock when you need to make a change.
📊
Inning scoreboard
Track runs inning by inning without leaving the app. The box score sits right above your batting order — type in a run and it updates the total instantly. No separate scorecard.
📱
iPad & tablet ready
Game Mode is designed for a tablet in the dugout. Large fonts, high-contrast colors, and a full-screen layout so coaches can glance at it from a few feet away without squinting.

Print & share

Your lineup on paper
in one tap.

Some coaches prefer paper. Some leagues require an exchange card. Six43 handles both. Print a clean dugout lineup sheet or a formatted exchange card ready to hand over at home plate — from your phone, tablet, or laptop.

✓Dugout lineup card — batting order with inning-by-inning positions
✓Exchange card formatted for the opposing team's coach
✓Print from desktop, tablet, or phone
✓Share a read-only link with your coaching staff

I used to scramble the night before every game. Now I build the lineup three days out, the pitching is already planned, and I actually enjoy coaching again.
