Could you build this?
Partial While pairing codes and simple state sync are standard, building native iOS Live Activities, Dynamic Island updates, and push-to-start ActivityKit notifications requires native Swift expertise and strict adherence to Apple's background execution lifecycle.
What it would actually take: The app requires a native iOS client built in Swift/SwiftUI leveraging ActivityKit, WidgetKit, and APNs (Apple Push Notification service with Live Activity update tokens). The backend needs a lightweight WebSocket or HTTP API (e.g., Node.js or Go with Redis) managing ephemeral pairing codes and dispatching high-priority APNs payload updates with custom push tokens. The primary difficulty is navigating Apple's restrictive APNs Live Activity budget limits and background wake constraints.
