Cross-Platform Cricket and other sports Scoring App

I’m creating a cricket-only scoring application that must run smoothly on both Android and iOS. The goal is to let anyone at a local ground enter ball-by-ball data while the general public follows the action in real time.

Core flow
• A scorer starts or joins a match, records each delivery, wicket, extra and substitution.
• Spectators instantly see live score updates, rolling text commentary and evolving player statistics.
• All data syncs to a lightweight cloud back-end but also caches offline so village grounds with shaky signals stay covered.

Key deliverables
1. Full mobile app codebase (one shared framework such as Flutter/React Native, or two native projects—your call, as long as both stores approve it).
2. Functional modules for:
– Live score updates (ball-by-ball push).
– Player statistics (per innings, match and season).
– Text commentary stream.
3. Simple match creation, team selection and shareable public link.
4. Basic, clean UI that a first-time user can navigate in seconds.
5. Admin panel or script to export match data (CSV/JSON).
6. Test builds and final binaries ready for Google Play and Apple’s App Store.

Acceptance criteria
• Latency between scorer input and public feed ≤ 2 seconds on 4G.
• Offline scoring retains all events and auto-syncs once connected.
• Verified passes of Play Console and App Store review.

You’re free to choose the stack, but please outline it in your proposal along with any past sports-scoring work. I’ll supply wireframes and branding once we kick off, and I’m happy to iterate quickly through TestFlight / internal testing until every over goes in flawlessly.
