What a PWA is, in plain words
A progressive web app, or PWA, is a website built to behave like an app. Visitors can add it to their home screen, where it opens full screen with its own icon. It can cache content so key screens still load on a weak or missing connection, and on platforms that support it, it can send push notifications.
Because it is still a website, there is one codebase for Android, iPhone and desktop, and updates reach users as soon as you publish them. There is no app-store submission, no review queue and no waiting for users to update.
When a PWA makes sense
- Field teams such as sales reps or service engineers who need forms and records on patchy mobile networks.
- Coaching institutes giving students quick access to schedules, notes and tests.
- Restaurants wanting a fast ordering app for repeat customers without asking them to download anything.
- Internal tools for staff, where app-store distribution adds effort without benefit.
- Startups testing an idea before committing to separate native apps.
A PWA is less suitable when you need deep access to device hardware, heavy background processing, or a presence in app-store search as a core part of your marketing. In those cases, a native or cross-platform app is the better route, and we will say so.
What’s included
- A responsive, app-like interface designed for touch.
- Web app manifest with name, icons and theme colours for installation.
- Service worker for caching and offline behaviour, scoped to what your use case needs.
- Offline data entry that syncs when the connection returns, where required.
- Push notifications on browsers and devices that support them.
- Login, user accounts and a secure back-end API.
- Install prompts and guidance, since installation steps differ between browsers.
How we build it
- Use case and offline plan. We decide which screens must work offline and what happens to data entered without a connection.
- Design. Mobile-first screens with app-style navigation.
- Build. Front end, API and caching strategy developed together.
- Device testing. We test installation, offline mode and notifications on real Android and iOS devices.
- Launch. The PWA goes live on your domain with HTTPS, which PWAs require.
- Iterate. Updates are deployed directly, without store reviews.
Technology
We build PWAs with React or Next.js, Tailwind CSS and a service worker managed with Workbox or an equivalent approach. Offline data is stored locally in the browser using IndexedDB and synced to the server when the connection returns. The back end is a standard secure API, which our API development team can also extend for other clients later.
PWA or native app: an honest comparison
| Consideration | PWA | Native or cross-platform app |
|---|---|---|
| Distribution | Shared by link and installed from the browser | Downloaded from app stores |
| Updates | Live as soon as you deploy | Go through store review and user updates |
| Codebase | One web codebase for all devices | Separate apps or a cross-platform framework |
| Device features | Common features such as camera, location and notifications, with browser limits | Full access to device hardware and background tasks |
| Discovery | Search engines and your own marketing | App-store search plus your own marketing |
For many businesses, the deciding question is simple: do your users need something only a native app can do? If the answer is no, a PWA usually gets you to launch sooner and keeps ongoing effort lower. If the answer is yes, or may become yes soon, we will recommend starting with a native or cross-platform app instead.
A PWA can also be a sensible first step. It lets you prove that people use the product before committing to store releases, and much of the back end can be reused later.
What affects timeline and cost
- How much of the app needs to work offline, and how conflicts are resolved on sync.
- The number of screens and user roles.
- Push notification and background sync requirements.
- Integrations with existing systems and data.
Common PWA mistakes
- Caching too aggressively, so users keep seeing an old version after an update.
- Promising full offline support without deciding how data conflicts are handled.
- Assuming iPhone behaviour matches Android.
- Treating a PWA as a way to avoid designing for mobile properly.
A PWA builds on solid responsive design. See all web development services, read the web development guide, or contact us to discuss whether a PWA fits your plan.
Frequently asked questions
Does a PWA work on iPhone?
Yes, with some limitations compared with Android. iPhone users can add it to the home screen, and installed PWAs can receive push notifications on recent iOS versions. We test on real devices and explain any gaps for your use case.
Can a PWA be listed on the Google Play Store?
It is possible to package a PWA for Google Play using Trusted Web Activity. It is not required, but it can help if store presence matters to you.
Is a PWA cheaper than a native app?
It usually needs less work because one codebase serves every platform and there is no store release process. Whether it is the right choice depends on the features you need.
Can users enter data offline?
Yes, where we design for it. Data is stored locally on the device and synced to the server when the connection returns, with clear rules for handling conflicts.
Can a PWA later become a native app?
The back end, APIs and much of the design carry over. The front end would be rebuilt or wrapped depending on the approach, so starting with a PWA is rarely wasted work.
