Unique Value

Not just a scorebook.
A system that runs the game.

Foundry isn't three features bolted together — it's one unified state machine. The moment you tap a play result, your lineup advances, your stats recalculate, and the next batter's song starts. That's the At Bat Engine.

01

Command Center Lineup

Drag-and-drop batting order with DP/Flex softball rules built in. Auto-validates for illegal substitutions, re-entry eligibility, and pitch count limits before you confirm.

02

Pro-Grade Scorebook

Ten one-tap outcome buttons. Interactive base diamond to advance runners. Live AVG, OBP, ERA after every call. Box score and spray chart generated automatically.

03

Ballpark DJ

Walk-up songs auto-queue via the At Bat Engine. Spotify, Apple Music, or local MP3. Soundboard, between-innings playlists, TTS announcer, and custom voice intros.

Core Features

Five systems.
One dugout screen.

01 / Lineup

Drag-Drop Lineup Builder

Build your batting order with haptic snap feedback. Assign defensive positions on an interactive field diagram. Save lineup templates for reuse across the season.

  • Softball DP/Flex dual-slot with ASA/USA rule enforcement
  • Re-entry eligibility highlighted before confirmation
  • Pitcher pitch count gate with configurable warning threshold
  • Printable lineup card PDF export
02 / Scorebook

Digital Scorebook

Traditional scorebook logic with one-tap input. Ten outcome buttons sized at 56pt minimum — legible and tappable in full sun with batting gloves on.

  • Interactive base diamond — tap to advance runners
  • Live AVG, OBP, SLG, ERA updating after every call
  • Spray chart with tap-to-mark batted ball location
  • Shake-to-undo last play — always available
03 / DJ

Ballpark DJ

Walk-up songs auto-start when a batter's cell goes active in the scorebook. Configure a start-point "drop" per player. Between-innings playlist triggers on the 3rd out.

  • Spotify Premium / Apple Music stream or local MP3 fallback
  • 1.5-second crossfade between ambient and walk-up tracks
  • 6-button soundboard — Crowd Roar, Woo, Organ, Rally
  • TTS announcer with custom voice recording per player
04 / Stats

Real-Time Stats Engine

Every plate appearance recalculates the full stat line instantly — no manual refresh, no end-of-game data entry. Season aggregates build automatically across games.

  • Hitting: AVG, OBP, SLG, OPS, K%, BB%, RBI, BABIP
  • Pitching: ERA, WHIP, K/9, BB/9, pitch count, FIP
  • Box score PNG share — one tap to team chat
  • CSV export compatible with GameChanger import format
05 / Engine

The At Bat Engine — Unified State

The intelligence core. A single GameEvent bus connects all three modules. Tap one play result and three things fire simultaneously: the scorebook records the play, the lineup strip advances to the next batter, and the DJ queues that batter's walk-up song. Zero manual coordination. One tap — the whole dugout responds.

  • Scorebook tap dispatches BATTER_UP event to all subscribers
  • Audio Engine crossfades to new walk-up within 1.5 seconds
  • 3rd out fires Between Innings playlist if Auto is enabled
  • Substitution reassigns walk-up song from roster automatically

Game Day Flow

From roster setup
to first pitch.

  1. App — First Launch

    Build Your Roster

    Enter players manually or import via CSV. Assign number, position, bats/throws. The moment you tap a player, their walk-up song slot appears — link Spotify, search Apple Music, or upload a local MP3 from your Files.

    → Each player's walk-up song travels with them across every game all season
  2. App — Pre-Game

    Set the Lineup

    Drag players into batting order slots. Tap any player to assign their defensive position on the field diagram. Foundry auto-validates: duplicate positions, illegal substitutions, DP/Flex legality — and warns before you lock in.

    → Lock Lineup fires a single tap → Game Day screen opens, ready to score
  3. App — In Game

    Score the Game

    The active batter glows amber in the lineup rail. Tap their plate appearance outcome — the diamond advances runners, the score updates, and their song fades as the next batter's walk-up crossfades in. One tap per plate appearance. That's it.

    → Full offline operation — all writes go to SQLite first, sync when signal returns
  4. App — Post Game

    Share the Box Score

    Final out triggers the Game Summary. Box score, individual hitting lines, spray charts, and season stats updated automatically. Share the box score as a PNG to the team group chat in one tap — or export the full scorebook as a PDF.

    → Season stats aggregate across all saved games — no manual data entry ever

Post-Game Reports

Full game summary.
One tap.

After the final out, Foundry generates a complete PDF — scorebook, box score, batting stats, and pitching summary — ready to print or share with parents and players.

  • Traditional scorebook grid with play-by-play results
  • Inning-by-inning box score (R · H · E)
  • Full batting stats — AB, H, R, RBI, BB, K, AVG
  • Pitching summary — IP, H, R, ER, BB, K, ERA
