Racing Odds Alert Mobile App -- 2

I’m building a mobile app that instantly alerts punters the moment fixed-odds prices go live for every gallops, harness and greyhound race in Australia and New Zealand that users select . The app must run natively on both iOS and Android and push real-time notifications drawn from the bookmakers I specify—Tab, Sportsbet, Ladbrokes, NZ Tab, Neds, Bet365, Dabble, Pointsbet and Tabtouch.

Core user flow
• On first launch a simple wizard lets the user pick the bookmakers and race meetings they care about, with the option to amend those choices at any time in Settings.
• When a selected bookmaker posts its opening market for a chosen meeting, the user receives a push notification that includes the bookie’s name, race meeting.
• Tapping the alert opens a clean screen showing the full fixed-odds board pulled directly from that bookmaker’s public API/page (no wagering inside the app).

Membership & paywall
Access is subscription-only. Monthly and annual plans will be offered through Apple and Google in-app purchases. Please include receipt validation and a simple admin flag so I can toggle “free trial” periods when needed.

Technical notes
• I’m platform-agnostic on the stack (Swift/Kotlin, Flutter, React Native, etc.) so long as notifications are truly real-time and the UI stays snappy.
• A lightweight backend will be required to monitor bookmaker feeds, deduplicate price releases across bookies, and trigger Firebase/APNs pushes.
• Source code, build instructions and store-ready assets must be handed over.

Deliverables
1. Clickable Figma or similar prototype for approval
2. Production-ready iOS and Android apps with in-app purchase subscriptions enabled
3. Backend service (hosted on my AWS account) to scrape/poll bookmaker odds and dispatch notifications
4. Brief admin web panel to view logs, manage user subscriptions and edit race-meeting lists
5. Store submission support through to live release

Acceptance criteria
• Push alerts arrive instantly when odds appearing on each bookmaker’s site.
• Users can individually toggle any of the nine bookmakers and any race meeting.
• Subscription flow works end-to-end on both platforms, including renewal and cancellation.
• Code passes App Store and Google Play review without compliance issues.

If this is comfortably in your wheelhouse, outline your preferred tech stack, estimated timeline and any past examples of live notification apps you’ve shipped.
