App feel, web reach

Progressive Web Apps That People Install

Asking customers to download an app is a big ask. Many will not, and building separate web, iPhone and Android versions is expensive.

A progressive web app gives you an installable, fast, offline-ready experience from a single web codebase. People open a link, add it to their home screen and come back through notifications they chose.

We build PWAs that work well on poor networks, test them on real devices and tell you honestly where a native app would serve you better.

Why it matters

From a plain site to an installable app

What changes when the web behaves like an app.

Before

A typical website
  • Customers must find, download and update an app from a store
  • The site is unusable when the connection drops
  • Separate web, iOS and Android teams and budgets
  • No way to bring users back after they leave the site

After

A progressive web app
  • Open a link, then add the app to the home screen in two taps
  • Key screens keep working offline and sync later
  • One web codebase for phones, tablets and desktops
  • Push notifications and a home-screen icon bring users back

What you get

Six capabilities that make it feel like an app

Delivered through the browser, from one codebase.

  • Phone icon

    Installable

    Users add the app to the home screen from the browser. It opens full screen with its own icon.

    Install
  • Cloud icon

    Offline-ready

    A service worker caches the app shell and key data, so people can keep working on a poor connection.

    Offline
  • Mail icon

    Push notifications

    Order updates, reminders and alerts that reach users who opted in, on supported devices.

    Re-engage
  • Bolt icon

    Fast repeat visits

    Cached assets make the second visit and every later one load far quicker than the first.

    Speed
  • Refresh icon

    Background sync

    Forms and orders made offline are sent when the connection returns.

    Sync
  • Globe icon

    One link for everyone

    Share by URL, find through search and update instantly, with no store review in the way.

    Reach

Where it fits

Good matches for a PWA

PWAs shine when reach, speed and cost matter more than deep device features.

We tell you early if your needs point to a native or cross-platform app instead.

  1. Store icon

    Retail and ordering

    Fast catalogues, saved baskets and order alerts.

  2. Users icon

    Field and service teams

    Checklists and forms that work in basements and rural areas.

  3. Calendar icon

    Bookings and memberships

    Reminders, passes and quick re-booking.

  4. File icon

    Content and news

    Offline reading and breaking-news alerts.

  5. Chart icon

    Internal tools

    Dashboards and approvals on any staff device, without app store setup.

  6. Spark icon

    AI assistants

    Chat and voice helpers that live in an installable app.

What we measure

Success beyond the install

We agree these measures at the start.

  • Repeat-visit speed

    Load time of the second and later visits, compared with the first.

  • Install rate

    Share of regular users who add the app to their home screen.

  • Offline success

    Tasks completed with no connection, then synced without loss.

  • Re-engagement

    Return visits driven by notifications users chose to receive.

How we work

From fit check to tested app

Five steps that keep a PWA dependable.

  1. Decide if PWA is the right fit

    Check which device features you need and whether the web can deliver them.

    Fit
  2. Design for thumbs and slow networks

    Mobile-first screens, light pages and clear offline states.

    Design
  3. Build the app shell

    Responsive front end, manifest and service worker with a cache plan per content type.

    Build
  4. Add native-feel features

    Install prompts, push, background sync and, where useful, camera or location.

    Extend
  5. Test on real devices

    Check iOS, Android and desktop browsers, plus airplane-mode and slow-network runs.

    Prove

Built to be trusted

What we verify before launch

The details that separate a PWA from a website with an icon.

  • Cache strategy per contentApp shell, data and images each get the right rule, so nothing goes stale unnoticed.
  • Safe updatesNew versions roll out without trapping users on an old copy.
  • Clear offline statesPeople always know what works offline and what is waiting to sync.
  • HTTPS and securityEncrypted traffic, safe storage and sensible permission prompts.
  • Cross-browser testedBehaviour verified on current iOS, Android and desktop browsers.
  • Lighthouse PWA auditInstallability and performance checks run before each release.

FAQs

Progressive web app questions, answered

A progressive web app is a website built with extra capabilities such as installing on the home screen, working offline and sending notifications, so it feels much like a native app while still running in the browser.

A PWA suits many business and content apps and costs less to build and maintain. Native apps are better when you need deep device features, heavy graphics or a presence in the app stores. We help you weigh this honestly.

Yes. On iPhone you add a PWA to the home screen from Safari, and push notifications are supported on recent iOS versions for installed apps. Some device features remain more limited than in native apps, so we test your needs early.

Yes, for what we plan for. We cache the app shell and key content and queue actions to send later. Features that need live data, such as payments, still need a connection.

Yes, on supported browsers and for users who opt in. We design when to ask permission and what to send, so notifications help instead of annoy.

Not necessarily. Many teams ship only the PWA. If you also want a store listing, a PWA can sometimes be wrapped for stores, though store rules apply.

A responsive website adapts to screen size. A PWA adds installation, offline use, background sync and notifications on top of that.

Yes, often as a first step. We add a manifest, service worker and offline plan, fix speed problems and test on real devices.

Upgrading an existing site often takes three to six weeks. A new PWA with accounts and sync typically takes two to four months.

Updating the service worker and dependencies, watching browser changes, checking performance and fixing issues, under a support plan with agreed response times.
