You don't need both, but most coaches use both. The web app is best for pregame planning at home — building lineups, setting up tournament plans, and reviewing stats on a larger screen. The iOS app is best for game day — scoring, pitch counting, and lineup adjustments from the dugout. Both access the same account and data syncs automatically.

Both apps have the same features. There's no feature locked to one platform. The difference is the interface — the web app is optimized for larger screens with more detailed views, while the iOS app is optimized for quick, one-handed interactions during live games.

Your account, roster, game plans, stats, and settings sync between both apps automatically. Build a lineup on your laptop Saturday morning. Pull it up on your phone Saturday afternoon in the dugout. The data is the same.
