Progressive Web Apps: Offline Web
Progressive Web Apps. Includes Service Worker Caching, App Manifest, Push API and Lighthouse Optimization — delivered by IQDigital's senior team.
A progressive web app (PWA) is a website that works like an installed app: it loads fast, works offline and can send push notifications. IQDigital builds PWAs with service worker caching, an app-shell architecture, home-screen installation and push re-engagement, from one codebase for desktop, mobile and tablet.
Who it's for
- Businesses that want app-like engagement without app store fees
- Users on unreliable mobile networks
- Teams that cannot maintain separate web and native apps
What is a progressive web app?
The gap between web and app has closed. Progressive Web Apps (PWAs) offer the reach of the web with the capabilities of a native app. IQDigital builds PWAs that are reliable, fast, and engaging. We utilize 'Service Workers' to cache assets and API responses, allowing your app to load instantly and function fully even when the user is offline or on a flaky network.
How installation and push notifications work
We implement 'Installability.' Users can add your PWA to their home screen directly from the browser, bypassing the friction and fees of the App Store. We utilize 'Push Notifications' to re-engage users, a feature once exclusive to native apps. We design for an 'App-Shell Architecture,' ensuring the UI loads immediately while content populates dynamically.
Why choose a PWA
PWAs are the ultimate efficient solution: one codebase that runs on desktop, mobile, and tablet. Google loves them (SEO boost), and users love them (no download wait). We ensure your PWA scores 100 on Lighthouse audits, delivering a best-in-class experience that redefines what a website can do.

Questions about Progressive Web Apps
Does a PWA work offline?
Yes. Service workers cache assets and API responses, so the app loads quickly and keeps working on a weak or missing connection.
How do users install a PWA?
Directly from the browser — they add it to their home screen without going through an app store.
Can a PWA send push notifications?
Yes. The Push API lets you send notifications to re-engage users, a feature once exclusive to native apps.
Is a PWA good for SEO?
A PWA is still a website, so its pages can be indexed by search engines, and we optimise it against Google's Lighthouse audits.
