A progressive web app is the right choice when your users mostly need fast access to information or simple transactions, and you'd rather not maintain separate store apps. If you need deep access to the phone's hardware, heavy offline work, or a presence in the app stores for discovery, a native or cross-platform app is still the better fit.
A PWA is a website that can behave like an app. It can be installed on the home screen, work offline for the parts you choose, and send notifications. It's built with web technology, so one codebase serves Android, iPhone and desktop.
What can a progressive web app do today?
- Install to the home screen without going through an app store
- Work offline or on weak connections, using a service worker to cache what matters
- Send push notifications. On iPhone this works for PWAs added to the home screen since iOS 16.4.
- Update instantly: users always get the latest version, with no store review in between
- Be found through Google like any website
Where does a PWA still fall short?
Be honest about the limits before you choose:
- Hardware access is narrower than native, especially on iPhone. Things like background location or Bluetooth are limited or unavailable.
- You don't get the discovery of the Play Store and App Store, and some customers expect an app to be there.
- Installation is less obvious to users than tapping "Install" in a store, so you need to prompt for it well.
PWA, native or cross-platform: how do they compare?
| Option | Best for | Codebases | App store listing |
|---|---|---|---|
| PWA | Content, catalogues, booking, simple ordering | One (web) | No |
| Cross-platform (Flutter, React Native) | Most business apps with richer features | One, built for both stores | Yes |
| Native (Swift, Kotlin) | Heavy hardware use, high-end performance | Two | Yes |
For most businesses we talk to, the real decision is between a PWA and a cross-platform app, not native.

Does it really make a difference to users?
It can. Twitter's PWA, Twitter Lite, is the classic example: Google's web.dev case study reports a 65% increase in pages per session and a 20% drop in bounce rate after launch. That's one large company's result, not a promise, but it shows how much speed on slow connections matters.
That point is especially relevant in India, where many users are on mid-range phones and patchy mobile data. A PWA that loads fast and keeps working offline can beat a heavy app nobody wants to download.
How do you decide?
Ask three questions:
- Do users need hardware features a browser can't reach? If yes, go cross-platform or native.
- Will people find you mainly through Google, or mainly through the app stores?
- How often will you release changes? Frequent updates favour a PWA.
If the answers are mixed, a PWA first and a store app later is a sensible path. Much of the backend carries over.
How long does it take to build a PWA?
It depends mostly on the features, not on the "PWA" part. Adding installability and offline support to a well-built website can be a small project. A full app-like PWA with logins, payments and offline data takes about as long as the equivalent web app, plus time to test it on real Android phones and iPhones.
If you already have a modern website, converting it is often the quickest way to test whether customers will use an app at all.
How Codelix builds them
We build PWAs with React and Next.js, and cross-platform apps with Flutter or React Native, so we're not pushing one answer. Our web development and mobile app development pages show both sides.
