Progressive Web AppDevelopment
A web app that installs like an app, loads fast on weak connections and works offline, without the cost of two native codebases.
Progressive Web App Development: what the work involves
Many businesses want an app but not the burden of building and maintaining separate iOS and Android versions, passing store reviews and asking users to download something heavy on limited mobile data. A progressive web app is a website that behaves like an app: it can be added to the home screen, opens full screen, caches content for offline use and, on supported devices, sends push notifications. For many products, that is enough.
We build the PWA on a single codebase with a service worker that decides what to cache and how to behave when the network drops. Core screens load instantly from cache, and actions taken offline, such as filling a form or logging a visit, queue and sync when the connection returns. We test on real mid-range Android phones and spotty networks. Where a native feature is genuinely required, we say so and plan for a later native wrapper.
Core features
Installable on the home screen
Users add the app from the browser, and it opens full screen with its own icon, without an app store visit.
Offline-capable screens
Key pages and data are cached so the app opens instantly and remains useful without a connection.
Background sync
Actions taken offline are queued and sent automatically when the network returns, so field work is never lost.
Push notifications
Order updates, reminders and alerts reach users on supported devices, with controls so people can choose what they receive.
Fast loading on weak networks
Code splitting, compressed assets and caching strategies make the app responsive on slow mobile data.
One codebase for all devices
A single build serves Android, iOS, tablets and desktops, which cuts development and maintenance effort significantly.
What we get right before launch
Platform limits on iOS
Apple supports PWAs but with restrictions on push notifications, background tasks and storage. We check each requirement against current platform behaviour before committing.
Offline data conflicts
Two people editing the same record offline create conflicts. We define merge rules, and where needed, show users what changed during sync.
Discoverability
PWAs do not appear in app stores by default. We plan how users will find and install the app, through your website, QR codes or optional store packaging.

Common questions, answered
Can a PWA replace a native app?
Often, for forms, content, booking and commerce. Apps needing heavy device access, such as advanced Bluetooth or background location, may still need native. We assess your requirements honestly before recommending a path.
Does a PWA work on iPhone?
Yes, with some limits compared to Android, notably around push notifications and background processing. We design with those constraints in mind and test on actual iOS devices throughout the build.
Will it appear in the app stores?
Not by default. A PWA can be wrapped for the Play Store, and Apple has stricter conditions. Many businesses simply promote installation from the website, which avoids store fees and review delays.
How does offline mode work?
A service worker caches the app shell and chosen data, and queues changes made offline. When the connection returns, the queue syncs and conflicts are resolved by rules we define with you.
