A PWA is a website that behaves like an app: it installs to the home screen, works offline, sends notifications. It sounds like an app at the price of a website, and that is exactly why it is so tempting. Sometimes it really is that. And sometimes it is a compromise you only discover when you need a feature web technology cannot reach. Here is how a PWA works, what it can and cannot do, and how to judge which path is right for your product.
What exactly a PWA is
A progressive web app is an ordinary website with three extra abilities. It installs: the visitor adds it to the home screen, and from there it opens full-screen, with an icon and no address bar, like any other app. It works without internet or on a weak connection: the content it needs is stored on the device. And it can send notifications that bring people back.
The key part is that all of this is still the same website: the code, the domain, and the place you update stay one. Every change reaches everyone immediately, with no stores, no versions, no “please update the app”.
What native can do that a PWA cannot
A native app is built specifically for iOS or Android and talks directly to the system. That is where the advantages come from, and web technology does not fully cover them.
- Direct hardware access. Bluetooth, NFC, sensors, health data, background geolocation: a native app uses them without restrictions, while a PWA is limited or blocked, especially on iPhone.
- Reliable notifications everywhere. On Android PWA notifications work well; on iOS they are possible but restricted in ways that are decisive for some products.
- Performance under heavy load. Video processing, 3D graphics, large volumes of data: native code has an edge you can feel.
- Store visibility. The App Store and Google Play are where people search for and discover apps. Being there builds trust and opens an audience.
- Experience down to the last detail. Smooth animations, gestures, transitions: a native app feels at home on the device in a way the web is still catching up to.
The honest comparison
| PWA | Native app | |
|---|---|---|
| Build cost | Close to the cost of a good website | Several times higher, often two platforms |
| Updates | Immediate, for everyone | Through the stores, with review and waiting |
| Installation | From the browser, in seconds | From the App Store and Google Play |
| Notifications | Good on Android, limited on iOS | Full everywhere |
| Device access | Limited | Full |
| Maintenance | One codebase, like a website | A separate product, sometimes two |
When a PWA is the right choice
A PWA wins when the app is essentially content and processes: a product catalog, bookings, online orders, a customer profile, a loyalty program, an internal tool for the team. It also wins when the budget is tight and the idea is still unproven: you launch the PWA and see how it lands, instead of investing in an expensive native experiment. And if you are wondering whether you need an app at all, we covered that question in mobile app or mobile site.
An existing website can also be upgraded to a PWA: if the site already does its job, adding installation and offline mode is a small step with a big effect.
When native is worth the money
The native path is the right one when the app is the core channel of the business rather than an addition to it. When you need features that do not pass through a browser: hardware, background processes, heavy graphics. When notifications are vital and a large share of your customers use iPhones. And when presence in the App Store and Google Play is part of the marketing: for many audiences, “they have an app” still reads as “a serious company”.
Once you decide the path is native, the second question follows: native with what? For most business apps, cross-platform development with React Native or Flutter delivers a native experience from a single shared codebase. We compared the approaches in our article on React Native, Flutter, and native development.
How we decide
When a client brings us an app idea, our first question is not “PWA or native” but “what needs to happen in your customer’s hands”. The feature list points the way on its own: if everything on it is achievable with web technology, a PWA protects the budget and speeds up the launch; if two or three key things hit the browser’s ceiling, we go native from day one so nobody pays twice later. In both cases the backend is designed to carry the future upgrade. That is the conversation our mobile apps service starts with.
The question is not which technology is better, but which is sufficient. Pay for capabilities your customers will feel, not for a label.
Frequently asked questions
What is a PWA in simple terms?
A website upgraded to behave like an app: it has an icon on the home screen, opens full-screen without browser bars, works on a weak or absent connection, and can send notifications. It is built with web technologies and lives on your domain, not in the app stores.
How much cheaper is a PWA than a native app?
Usually several times cheaper. A PWA is one codebase that is also your website, while a native app is a separate product, often in two versions for iOS and Android, plus publishing and store maintenance. When a PWA covers the needs, the difference is tens of thousands of leva.
Does a PWA get into the App Store and Google Play?
A packaged PWA can be published to Google Play. With Apple things are more restricted: a PWA installs from Safari but does not appear in the App Store as a full app. If store presence matters for trust and discovery, that is a point for the native path.
When is a PWA not enough?
When the product relies on deep system features: Bluetooth and sensors, heavy video and graphics processing, background processes, full notifications on iOS, store payments. And when the app is the business itself and the experience has to be flawless down to the last detail.
Can I start with a PWA and move to native later?
Yes, and that is often the most sensible plan: the PWA tests demand on a small budget, and if the product takes off, the native app is built on a proven model. The key is designing the backend to serve both, so the transition is an upgrade rather than a restart.
