01
Faster Repeat Visits
Service workers can cache selected assets and data to reduce repeat loading, based on the product's connectivity requirements.
02
Offline Functionality
Users can continue using core features of your application even without an internet connection, thanks to intelligent caching.
03
Home Screen Installation
Users can install your PWA to their home screen without visiting an app store, lowering the barrier to engagement.
04
Push Notifications
Re-engage users with timely push notifications just like a native app, without requiring an App Store presence.
05
No App Store Dependency
Deploy updates instantly without waiting for app store review cycles, giving you full control over your release schedule.
06
Reduced User Friction
Installable access, appropriate caching and focused interactions can make frequent tasks easier for returning users.
What is included
The exact scope is agreed in your written quote before work starts.
Service Worker Implementation

Full manifest configuration enabling home screen installation with your app name, icon, splash screen, and display preferences.
Push Notification System
Web Push API integration with a notification management system to send targeted, segmented messages to opted-in users.
Offline-First Architecture
Data synchronisation and conflict resolution strategies that keep your app functional and data consistent when connectivity drops.
App Shell Architecture
An application shell can provide early visual feedback while dynamic content loads in the background.
Background Sync
Queue and replay user actions made while offline so no data is lost when connectivity is intermittent.
Performance Optimisation
Lighthouse checks and real-device testing identify loading and interaction issues before launch.
Cross-Platform Compatibility
PWAs tested across Chrome, Safari, Firefox, and Edge on both iOS and Android to ensure consistent behaviour everywhere.

Frequently Asked Questions
Do PWAs work on iPhone as well as Android?
Yes, though with some limitations on iOS. Safari on iPhone supports service workers, home screen installation, and offline functionality. Push notifications on iOS require iOS 16.4 or later and the PWA to be added to the home screen first. We design and test our PWAs to work well on both platforms.
Is a PWA a replacement for a native app?
For many use cases, yes. PWAs are suitable when you need broad reach without App Store distribution, and where your features don't require deep device access (camera, NFC, Bluetooth beyond Web Bluetooth). For highly complex native integrations, a native or cross-platform app may be better — we'll advise honestly during discovery.
How does a PWA compare to a regular website for performance?
A service worker can cache selected resources locally, which may make repeat visits faster and preserve some functions when connectivity is poor. The result depends on the content, device, network and caching strategy, so we test the important journeys rather than promise a fixed loading time.
Can an existing website be converted into a PWA?
In many cases yes. Adding PWA features — service worker, manifest, HTTPS — to an existing site is often straightforward. The degree of offline functionality achievable depends on how your current site is structured. We'll audit your site and advise on the conversion complexity.
Can a PWA be found through Google search?
Yes, and this is one of PWAs' major advantages over native apps. Because a PWA is served over the web, it's fully indexable by Google. Combined with strong SEO, your PWA can rank in search results and drive organic traffic, something native apps cannot.
