Progressive
web app development
in Philadelphia

PWAs require HTTPS, service workers for offline functionality, web app manifest for installability, responsive design, and progressive enhancement architecture.

Yes. We develop progressive web apps for Philadelphia companies needing app-like experiences without platform-specific development.

Service workers intercept network requests, cache assets and data locally, and serve cached content when offline or on slow connections.

Typically 8-14 weeks depending on feature complexity, API integrations, offline requirements, and existing infrastructure.

Geolocation, camera, microphone, push notifications, background sync, payment request, storage, sensors, and most device capabilities modern browsers expose.

PWAs use web technologies, run in browsers, update instantly, and work cross-platform. Native apps access more device features but require platform-specific development.

Cache-first for static assets, network-first for dynamic content, stale-while-revalidate for balanced approaches, and custom strategies based on requirements.

Yes. iOS supports PWAs with some limitations compared to Android, but core functionality including installation and offline capability works.

Through background sync API, queuing failed requests, syncing when connectivity returns, and maintaining data consistency across sessions.

PWAs eliminate platform dependencies, reduce development costs, enable instant updates, provide universal access, and leverage progressive enhancement.
