Progressive Web Apps
Progressive Web Apps combine the best of web and app: they run in the browser, can be installed on the home screen, send push notifications, and work offline – without the store barrier.
Progressive Web Apps Without the App Store
For many use cases a PWA is the smarter choice than a native app: immediately accessible, platform-agnostic, and built on a single codebase for all devices.
The essentials of Progressive Web Apps
- Progressive Web Apps run in the browser, install on the home screen, send push notifications and work offline – without the store barrier.
- A service worker intercepts network requests and caches resources so the app delivers even without an internet connection – with careful cache invalidation against stale versions.
- A PWA runs on iOS, Android and desktop from a single codebase, without separate builds and without store management across multiple platforms.
- We show the install prompt at the moment the app has proven itself, rather than pushing for it on the first visit.
- Because a PWA runs over a URL, we optimise load time and stability for ranking and conversion, turning it into an acquisition channel.
Service Worker
At the heart of every PWA is the service worker – a background process that intercepts network requests, caches resources, and delivers the app even without an internet connection. We implement caching strategies that enable offline experiences without degrading the user experience when a connection is available.
Web App Manifest
The web app manifest defines how the PWA behaves once it is installed on the home screen: app name, icons, splash screen, start URL, and theme colour. We configure the manifest so that the installed PWA is barely distinguishable from a native app.
Push Notifications
PWAs can – on compatible platforms – send push notifications even when the browser is not open. We implement push infrastructure via the Web Push API, with opt-in flows and notification management that match mobile user expectations.
Installation and Discoverability
PWAs are shared and found via URLs, not through stores. This dramatically lowers the barrier to entry: users click a link rather than initiating a store download. We optimise the install prompt and web presence for maximum reach.
PWA vs. native app
Not every requirement needs a native app – and not every project fits a PWA. This comparison shows where each approach is the right answer.
| Native App | Progressive Web App | |
|---|---|---|
| Distribution channel | App Store / Play Store | URL – instantly accessible |
| User entry barrier | Download & install required | Open, experience, optionally install |
| Platform codebase | Separate iOS and Android builds | One codebase for all devices |
| Offline capability | ||
| Push notifications | ✓ (full support) | ✓ (limited on iOS) |
| Hardware access & system depth | ✓ (full support) | Limited – browser-dependent |
Honest guidance on the right approach is part of good PWA consulting.
What matters in a PWA
Not all aspects of PWA development carry equal weight. These factors separate a PWA that runs reliably and retains users from one that squanders its own advantage.
- Caching & update strategy (Service Worker)Determines offline experience and seamless updates
- Load performance & Core Web VitalsURL-based access makes performance an acquisition channel
- Install prompt timingToo early = conversion loss; after first value = acceptance
- Push notification strategyRelevant, but iOS restrictions limit reach
- Knowing & communicating platform limitsWhere PWA falls short, native app belongs in the recommendation
Relative weighting
Weighting by influence on user experience and reach – not measured metrics.
What matters for Progressive Web Apps
What matters with a PWA is the update and caching strategy, because it decides the experience after the first visit. A service worker can deliver content instantly or stick users to an outdated version, depending on how carefully you solve cache invalidation and versioning. This is exactly where a PWA that runs reliably separates from one nobody can get updated.
A PWA installs best once the user has already experienced the value. The install prompt does not belong at the start but at the moment the app has proven itself. A PWA that pushes for installation on the first visit gives away the very low-barrier advantage that defines it.
Honesty about the limits is part of good PWA work. iOS restricts push and background processing, and not every native interface is equally available in the browser. We choose the PWA where its strengths hold, namely reach, discoverability, and a single codebase, and say plainly where a native app would be the better answer.
And because a PWA runs over a URL, performance is not a side topic but the acquisition channel. Load time and stability decide ranking and conversion the same way they do for any website. A fast, offline-capable PWA wins users; a sluggish one loses them before it is ever installed.
No Store Barrier
PWAs are shared via URLs and used immediately. The install option comes as a contextual prompt – not as a mandatory prerequisite. This significantly lowers the entry barrier compared to native apps.
Offline-First Possible
With service workers and strategic caching, PWAs can function without an internet connection – from a simple offline fallback to full offline usage.
One Codebase, All Platforms
A PWA runs on iOS, Android, and desktop from a single codebase. No separate mobile and desktop builds, no store management across multiple platforms.
