Android Sports Scoring App

I need an Android application that lets me run live scoring for cricket matches and, with minimal tweaking, handle football and other team sports as well. The core of the job is to create a clean scoring workflow that pushes live score updates instantly to every user, captures detailed player statistics in the background, and lets me schedule upcoming fixtures straight from the same interface.

Three access levels must exist inside the app. An Admin can configure teams, competitions, and user permissions; a Scorer can enter ball-by-ball (or play-by-play) data during play; and a Viewer can simply follow matches in real time. Each role should see only the screens it needs, and role switching has to be seamless.

I expect intuitive UI/UX that keeps scorers fast and error-free, a lightweight onboarding process for viewers, and a back-end architecture that could scale to multiple concurrent games without lag. If you plan to use Firebase, Supabase, or another real-time database, please mention it; I’m open to suggestions as long as updates appear instantly on even a low-end device.

Deliverables must include:
• Play-ready APK for testing and final release
• Complete, well-commented source code
• Short setup guide covering build steps, environment, and how to extend the rules engine for new sports

If your previous work shows crisp real-time performance and an eye for sports data presentation, I’d like to see it with your proposal.
