For youth baseball leagues
Know who can
pitch today.
Pitch counts and rest days that add up across every team a player is on — not just the one you coach.
14-day trial · one price for the whole league · set up in an evening
Two adults each see half of his week.
Every other app is built around a team — a coach's roster, a travel club, a program. In that model a player belongs to one list and the question never comes up.
Jake pitched 45 for the Cardinals on Saturday. Tuesday his All-Star coach pencils him in. In every other app, that coach sees a fresh arm.
In a real league, the kid on two rosters is exactly the one most likely to get overpitched.
League-wide, not team-wide
One player has one standard team, and can also be on All-Star or Select. Counts and rest sum across all of them, automatically. The league owns the data, not a coach.
Your board's rules, not a preset
Divisions, per-outing caps and rest tiers are yours to edit. Boards settle their limits a week before opening day — change them that evening, without asking anyone.
You will never live-log an inning
You open ArmLog twice: before the game, to see who’s rested, and after it, to type in what each pitcher threw. That’s the whole app. No scoring, no lineups, no charting, no AI. A volunteer can use it correctly at 6pm on a Tuesday without being trained first.
Built for a real league, by the person
who was doing its pitch counts.
Not a prototype. The app ArmLog grew out of ran a full season for a youth baseball league in Ontario:
One price for your whole league.
Not per team. Not per coach. Not per parent. Less than a single team pass on the app your league already knows.
- Every division, every team, unlimited coaches and parents
- Paste your roster in to get started — not a weekend of setup
- The trial takes no card, and says what it costs before day one
- Cancel yourself, from inside the app, whenever the season ends
Takes about five minutes. You'll have a working league before you decide anything.
