We are developing a fully featured, cross-platform referee app system that will be very similar to REFSIX, but enhanced with biometric sync, role-specific workflows, and live coordination across all match officials. The system will support five separate apps—one per sport:
• Football (Soccer)
• Futsal
• Rugby Union
• Rugby League
• Tennis
Each app will have its own branding and rules, but share a unified codebase, architecture, and core functionality.

Scope of Work – Phase 1
1. Design
• Branding:
• Unique logos and color themes for each sport.
• UI/UX Design:
• Refined match control UI (like REFSIX) for mobile and smartwatch.
• Web/tablet dashboards for assessors and managers.
• Sync status indicators, touch-based timers, and live match data visibility.

2. Build
Tech Stack:
• Frontend: React Native + Expo SDK, Tamagui UI, native watch modules.
• Backend: NestJS (REST API), PostgreSQL, Firebase Auth, AWS S3, Redis Streams.
• Local Storage: MMKV (mobile), CoreData (iOS), IndexedDB (web).
Devices Supported:
• iOS + Android phones
• WearOS + watchOS
• Tablet / Web (Next.js)
Sync Architecture:
• BLE device pairing for watch-to-phone sync
• Firebase + Redis Streams for live sync across officials, assessors, and managers
• Role-based visibility and real-time updates between:
• Referees
• 4th Officials
• Assessors
• Managers
• Admins

3. Sport-Specific Functionality
Football / Futsal:
• Cards, goals, stoppage time, misconduct, substitutions.
Rugby Union / League:
• Blood timer, HIA, sin-bin, scrum resets, substitutions.
Tennis:
• Points, sets, medical timeouts, challenges.
Each app will reflect sport-specific timing, flow, and terminology.

4. Testing
• BLE sync validation between watch + phone
• Cross-device sync between referee roles and assessor views
• Offline behavior + recovery
• Multi-device match simulation with 3+ connected roles
