The Book

Not just the line score.

The Book records the whole play — every fielder in the sequence, the batted ball, the error, each runner's advance, the earned and unearned runs — in Retrosheet notation you can export and keep.

The mark the app draws for every plate appearance — a run filled in, an out in pencil.

What it records

Play-by-play notation
Fielder sequences, batted-ball type and location, error type, every runner's advance, earned and unearned runs. The full Retrosheet event field, written as you score: S8/G.2-H(RBI);1-3.
MLB and minor leagues
Browse the season in progress or seasons past — standings, schedules, rosters, from the majors through Triple-A down to Rookie ball. Load a real lineup and score the game, or hand-enter any game at any level.
Box scores and exports
A conventional box score from every game. Export a PDF scorecard to hand around after the final out, or the Retrosheet .EV file to archive in a format that outlives any one app.
Offline first
The game is scored on your device. No signal at the field is fine — nothing in the scoring pad waits on a network.
Backup to your own Google Drive
Sign in with Google and your scorebook backs up to a private per-app folder in your Drive. There is no account on anyone else's server; the developer runs none and cannot see your games.

The notation says what happened

A scorebook has its own shorthand, worked out over more than a century. The Book reads and writes it, and shows you the play in plain English while you learn.

S8/G.2‑H(RBI);1‑3

A ground-ball single to center. The runner on second scores — the batter is credited with the RBI — and the runner on first pulls up at third.

64(1)3/GDP

Six to four to three. The shortstop flips to second to retire the runner coming from first, and the throw across doubles off the batter.
