This document discusses using push notifications for a web app without needing to hire iOS and Android engineers. It considers adopting a progressive web app (PWA) or using services like React Native, but notes PWAs do not support push notifications on iOS. It then introduces Push7 API as a solution that can provide push notifications to iOS even without a native app. The architecture involves a service worker, web browser, and Apple Push Notification Service, with Push7 in the middle to handle notifications across platforms with small requirements and wide extension capabilities.
