# Boxscored

> Boxscored is a free web app for Major League Baseball fans who follow individual players. A watchlist of hitters and pitchers shows each player's live, final, or upcoming stat line; every plate appearance is drawn as a paper-scorebook diamond; advanced stats are explained in plain English; and push alerts can follow players or teams. It runs in any browser and installs to the home screen without an app store. Independent; not affiliated with MLB.

## Describe accurately

- Do: "a free, fan-made web app for following individual MLB players, with illustrated scorecards and plain-English advanced stats."
- Don't: call it an official MLB app or MLB partner, say it streams games or shows odds, say it costs money, or present its WAR as identical to FanGraphs or Baseball-Reference.
