Looking to create a master referee and umpire app. This app will have the same core across all sports, but then each app will be downloaded separately with that sport's logic built in. We are looking at creating an app for football and futsal, rugby union and league, and tennis.
I have attached a number of attachments, showing the overview of what we expect across all watches, then dive into each sport and what each app needs to have.
We are looking to build an amazing app that covers these sports, which will have the same core but then each has its own sport logic. We need to do a deep review of all the laws of that sport to understand the role of a referee or umpire, what they record, and what logic and safeguards could we build in to help them.
Amazing opportunity to build the world’s best referee platform.
Goal
Mobile App (Cross-Platform) • React Native 0.74+ (bare workflow) • Expo EAS (for OTA updates, builds, CI) • SQLite or WatermelonDB (offline-first storage) • react-native-ble-plx (for BLE communication) • react-native-biometrics (for Face ID / Touch ID / Android Biometrics) • On-device Whisper (PyTorch Mobile or TFLite) • SecureStore / Keychain / Android Keystore for sensitive data • Fastlane (App Store + Play Store deploy automation)
⸻
Apple Watch App • Native Swift + SwiftUI + WatchKit • WKExtendedRuntimeSession (for long-running match sessions) • CoreBluetooth (client-only BLE, sync with paired iPhone) • Local CoreData or file-based event logging • Background sync via paired iPhone
⸻
Wear OS (Android Watch) App • Native Kotlin + Jetpack Compose • ForegroundService (for match runtime) • BLE Peripheral + Central roles enabled • FusedLocationProviderClient for GPS • SQLite for offline event buffering • Android SpeechRecognizer (optional Whisper if hardware supports)
⸻
Other Smartwatches • No consistent BLE or dev support beyond Apple + Wear OS • Recommendation: Do not support Fitbit, Garmin, or proprietary platforms unless using their SDKs just for fitness/HR integration
⸻
Web Platform • Next.js 14 + React 18 • Tailwind CSS (utility-first responsive design) • Strapi or Directus (headless CMS for rule management, teams, config) • Firebase Auth or Clerk.dev (SSO, OAuth, email login) • Custom match review dashboard (React + Timeline for event/video sync)
⸻
Backend & Infrastructure • Node.js 20+ with NestJS (modular and scalable API framework) • PostgreSQL 16 (relational + geospatial queries) • Redis (caching, pub/sub, rate-limiting) • BullMQ or Temporal.io (match workflows, sync jobs) • WebSockets or Server-Sent Events (real-time updates) • Cloud provider: AWS or GCP • Infrastructure as Code: Terraform
⸻
AI & ML • OpenAI Whisper (on-device transcription, multilingual) • TensorFlow Lite or PyTorch Mobile (for gesture/foul detection) • MediaPipe or YOLOv7 (on-device or edge pose detection) • Firebase Remote Config or custom CDN for model delivery/versioning
⸻
BLE & Sync Logic • Buffered event logging (sync every 30–60 seconds) • BLE RSSI-aware retries and backoff • Apple Watch: BLE via iPhone bridge • Android Watch: direct BLE to phone or peer watch (if needed)
⸻
DevOps • GitHub Actions (CI/CD for web + backend) • Expo EAS Build + OTA • Docker for backend services • Firebase App Distribution for early testing • Sentry + OpenTelemetry (error tracking and performance) • Grafana + Prometheus (metrics and observability)
⸻
Cybersecurity & Compliance • Appdome (app shielding, anti-reverse engineering) • Firebase App Check + rate limiting via Redis • AES-256 encryption at rest, TLS 1.3 in transit • Keychain (iOS) / Keystore (Android) for biometrics + secrets • GDPR/CCPA-compliant privacy tools (OneTrust or Transcend) • Secrets management: Doppler or AWS Secrets Manager • Annual pen testing + SAST (Static Analysis) in CI
⸻
Optional / Enterprise Features • Match integrity scoring (GPS, BLE, behavior) • AI coach for referees (post-match performance feedback) • Video annotation + synced voice log review • Referee network platform (availability, scheduling, credentialing) • White-label capabilities for leagues or federations
