DiamondKeeper is the free scorekeeping app that also assists umpires, builds rules-legal fielding rotations, streams your games with no YouTube or Facebook, and runs your whole league.
Built by a local baseball parent, for coaches, umpires, families, and leagues.
Pitch-by-pitch with a tap strike zone, spray charts, pitch velocity, steals and base-running, and one-tap “tricky plays” — quick enough to keep up live.
Live game clock with a time-limit alert, pitch-count compliance with required rest, pitcher-eligibility list, and call review with slow-mo frame-step.
Fatigue Watch flags a tiring arm from a velocity drop, and a league-wide pitch-count report catches any pitcher over the max or on short rest.
Auto-build a fair rotation that guarantees Little League, PONY, Cal Ripken, or Babe Ruth mandatory-play minimums — and flags anything that won’t comply.
Batting and pitching stats that build all season, plus downloadable spray and strike-zone charts for every player.
Season leaderboards and an all-time record book (down to stolen bases), with tap-to-share player moment cards.
A one-tap official game report for the scorebook, plus an auto-written news-story recap with an animated top-plays reel.
Go live from a phone in one tap, or a Mevo/OBS camera — straight through your own stream, no YouTube or Facebook. Families watch on a share link.
A share link + QR shows the live scoreboard, field, spoken play-by-play, win probability, box score, and video — no login, nothing to pay.
Coaches keep score, parents follow along, umpires stay compliant, and league admins get a real dashboard.
Every game feeds season batting & pitching stats, spray and strike-zone charts, live Leaders, and an all-time Record Book. Finish a game and DiamondKeeper writes a one-tap official report for the scorebook plus an auto news-story recap with a top-plays reel — ready to share.
Free to score and free to watch — always. You only pay for the coaching edge and running a league. Priced per season, not per month.
Open DiamondKeeper in any phone browser and add it to your home screen — or reach out about bringing it to your league.
