Lineup Tracker
A mobile-first PWA for managing baseball and softball dugout lineups — shareable via QR code, no app store required.
Problem
Little league and church league coaches needed a simple way to manage batting lineups for multiple teams in the dugout. Paper lineups get lost, and handing off to another coach mid-game, especially between innings, meant losing track of who was up next.
Solution
Built a progressive web app with React that coaches can save to their home screen like a native app, no install required. Coaches can build and manage lineups for multiple teams, track the batting order across innings, and share a lineup instantly with another coach via QR code.
Outcome
Coaches have a lightweight, always-available tool that lives on their phone and works without an internet connection. Lineup handoffs between coaches take seconds, and nobody loses their place in the order.
