Why I built this
I'd wanted to learn to keep a scorecard for years. It finally clicked when my son joined Little League and I volunteered to score his games — I picked up scorecards at Rockies games and taught myself the notation right there in the stands. Since then I've kept score a handful of games every season, but never loved carrying a paper pad around, and I'm forgetful enough to leave it behind half the time.
A while back I built an open-source PDF framework for my Kindle Scribe — kindle-scribe-generator — and one of the templates was a baseball scorecard. It worked, but the Scribe's slow refresh and clumsy pan-and-zoom made it a poor fit for scoring live. My phone, on the other hand, is always in my pocket — so I set out to reimagine scoring for the iPhone, where freehand drawing needed rethinking to work well on a small touch screen.
That became Boxscore9: keep team rosters, build lineups from them, score with or without balls and strikes, handle substitutions and extra innings, and export a finished scorecard as a PDF to share. Now I always have a way to score a game — just open the app and go, even for a few innings. I hope you enjoy it — feedback is welcome at boxscore9@parallelhours.io and I'll try to work it in.
