How it works

Plan ahead. Coach better.

Six43 is built for the work that happens before you ever step on the field.

1
Set up your season
Add your roster once — jersey numbers, positions, batting preferences. Import your schedule from GameChanger or enter games manually. Done in minutes.
2
Plan every game
Build lineups ahead of time. Track pitching rest days. Set up tournament weekends before the schedule drops. Everything ready before you leave the house.
3
Coach with confidence
Check attendance on game day, pull up your lineup, and step into the dugout prepared. Playing time data and pitch counts update automatically after every game.

Lineup builder

Your lineup, done
the night before.

Most coaches build their lineup the night before the game. Six43 makes that 45-minute process take 10. See every player across every inning at once, paint positions with a click, and you're done — ready to share or print before you go to bed.

✓Full grid — every player, every inning, all in one view
✓Paint positions with keyboard shortcuts or click-to-fill
✓Shift+click to fill a range across multiple innings at once
✓Share with your staff or print a clean card for the field
Playing time view
Playing time

Be fair to every kid —
and prove it.

See bench time and innings by position for every player, every game, all season. Set targets and get flagged before anyone's being overlooked — so you're ahead of the conversation, not responding to it after the game.

✓Bench % tracked per player, per game, all season
✓Set an innings target and track progress toward it
✓Check fairness before building the next lineup
✓Per-game breakdown: who played where and when
Pitching planner
Pitching planner

Know who can pitch
three days before game day.

Log pitch counts after each game and Six43 calculates rest days to your next scheduled game automatically. Know exactly who's eligible and who needs more time — before you're standing on the mound making a decision on the fly.

✓Pitch counts logged per game, rest days calculated automatically
✓See eligible pitchers at a glance before every game
✓Season totals and over-limit warnings built in
✓Plan your pitching rotation for the whole weekend

Tournament planning

Plan the whole weekend
before the bracket drops.

Tournament schedules are never finalized until the last minute. Set up placeholder games for pool play and bracket rounds ahead of time — so you can start planning lineups and pitching rotations before you even know the opponent. When the real schedule comes in from GameChanger, swap with one tap and your work carries over.

✓Create pool play and bracket slots before the schedule is set
✓Build lineups on placeholders — they carry over when you swap
✓GameChanger sync suggests which imported games match your placeholders
✓Stale placeholders are flagged if the date passes without a swap

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.
