Part of every play.

Diamond Crew teaches kids the same notation used by official scorekeepers — guided at-bat by at-bat, so the scorebook is theirs to keep.

What it is

A real scorebook
for real families.

Diamond Crew is a baseball scoring app built around five modes that grow with your scorer — from a 5-year-old’s first dugout taps all the way up to full official notation.

Every at-bat is captured with real scorebook notation: 6-4-3 double plays, fielder’s choices, infield fly rule, dropped third strikes, balks. Pitch-by-pitch BSO and pitch counts. Earned vs. unearned runs. Inherited runners credited to the right pitcher.

When the game ends, email the box score — line score, batting lines, pitching lines, all the math done — directly from your phone.

Five modes

Grows with your scorer.

Start with Dugout Mode and a five-year-old who taps when something happens. End with Pro Mode and notation a college coach would recognize.

01
Dugout
Ages 5–8

Big buttons. No notation. Tap when something happens. A great way to feel involved without the pressure of scorekeeping.

02
Rookie
Ages 8–11

Hits, outs, walks, runs. Guided prompts after every at-bat. The line score is yours by the end of the game.

03
All-Star
Ages 11–14

Real scorebook notation begins. Fielder positions, ground outs by chain, basic pitching tracking.

04
Scout
Ages 14+

Pitch-by-pitch tracking. BSO. Errors credited to the right player. Inherited runners. Double plays by sequence.

05
Pro
Serious scorers

Full official notation. Balks. Infield fly. Dropped third strikes. Earned vs. unearned. The whole scorekeeper’s vocabulary.

Features

Built for the dugout.

Designed for one-handed phone scoring while a game is happening around you. Bluetooth-ready for the optional Diamond Crew Scoreboard.

Notation

Real scorekeeping

6-4-3 double plays, fielder’s choices, dropped third strikes, balks, infield fly. The same notation used in official scorebooks for over a century.

Email

Box score by email

After the final out, tap to email the box score. Line score, batting lines, pitching lines — the math is done. From your phone, to whoever wants it.

Stats

Season-long stats

Each scorer profile tracks games across a season. Batting average, RBI, strikeouts, walks — by player, by team, by season.

Family

Multiple scorers

One account, multiple scorer profiles. Siblings share an app. Parents and kids each get their own scorebook. Coach mode tracks team rosters.

Engagement

XP and predictions

Kids earn XP for scoring games. Pre-game predictions add a layer of fun that keeps them locked in from first pitch to last out.

Bluetooth

Hardware-ready

Pair with the optional Diamond Crew Scoreboard over Bluetooth for a working count, inning, and outs display right at the dugout — whatever field you happen to be playing on.

Coming soon

The Diamond Crew
Scoreboard.

A portable LED scoreboard that pairs with the app over Bluetooth. Compact enough to sit at the end of the dugout or on a bench — visible to the team and the families nearby. For the games at fields where the scoreboard is broken, missing, or never existed in the first place.
