For coaches

The paperwork,
done properly

You volunteered to coach, not to keep a spreadsheet of pitch counts. This does the counting and the rule-checking so you can spend the hour before a game on something else.

Regular Season Pitching Rules (Regulation VI)

Check it against your rulebook

The calculation above is the same code the planner runs, with the same rule data and the same sources. It is shown before you sign up because a tool that does arm-safety maths should be checkable by the person relying on it.

What you get

Pitch availability

Every arm on the roster across the next fourteen days. Rest days counted from Regulation VI, and outings from other teams counted too — that is the part most tools miss.

Roster

Names optional. Paste a list from a team email and it splits jersey numbers from names on its own.

Lineups and fair-play rotations

Coming soon

Batting order and a rotation grid that will not seat the same kid twice, printed on one page.
