Airship is a real-time engagement platform that uses APNs to deliver event-driven, stateful user experiences. It manages multi-stage lifecycles (pre-event, active, post-event) and continuously updates user-facing content through push-based triggers and scheduled workflows.

The system combines APNs updates, event processing, and time-based orchestration to keep user data in sync across a session.

This directly aligns with Apple Wallet requirements, where a pass or Live Activity needs to be updated dynamically over time via APNs, based on events like trip status, timing, and user activity.
