Not every business needs an app in the App Store. A progressive web app — a website that behaves like an app, can be installed to the home screen and works offline — can deliver much of the experience at a fraction of the cost and without app-store gatekeepers. But PWAs have real limits, and for some products only a native or cross-platform app will do. This guide compares the options honestly so you can decide where a PWA is the smart choice, where it is not, and how to start small.

What is a PWA?
A progressive web app is built with standard web technologies but adds three things: a web app manifest (so it can be installed with an icon and full-screen experience), a service worker (so it can cache content and work offline or on poor connections) and a secure HTTPS connection. To the user it looks and feels like an app, yet it lives at a web address and needs no download from a store.
PWA vs. native: side by side
| Factor | PWA | Native / cross-platform app |
|---|---|---|
| Distribution | A link; optional install to home screen | App Store and Google Play |
| Build cost | Typically lower — one web codebase | Higher (cross-platform is cheaper than two native apps) |
| Updates | Instant, no store review | Through store review (usually quick, but not instant) |
| Offline | Yes, with caching strategies | Yes, with more control |
| Push notifications | Supported on many platforms, with limits that vary | Full support |
| Device access | Growing but limited (some sensors, files, camera) | Deep access: Bluetooth, background tasks, advanced sensors |
| Store discoverability | Weak — found via search and links | Strong — store search and featuring |
| Performance | Very good for most business apps | Best, especially for graphics-heavy apps |
Capabilities vary by browser, operating system and version; verify the features you need on your target devices.
When a PWA is a great choice
- Content and commerce: catalogues, booking, stores and portals where speed and reach matter.
- Internal tools: staff can open a link — no app-store distribution or device management.
- An MVP: test demand cheaply before committing to store apps (see the MVP development guide).
- Markets with low-end devices or poor connectivity: small, fast, offline-capable apps help.
- You want one codebase for web and mobile.
When you need a native or cross-platform app
- Deep hardware access: Bluetooth devices, background location, advanced camera or AR features.
- Heavy graphics or real-time processing: games, video editing, complex animations.
- Store presence matters: your audience expects to find you in the App Store or Google Play.
- Consistent push notifications and background tasks are central to the product.
- Platform-specific integrations: wallet, health data, widgets and similar.
Lean towards a PWA
- Your product works well in a browser
- Budget and speed matter most
- You need reach through links and search
- Notifications are helpful but not critical
Lean towards a store app
- You need deep device features
- Store visibility is part of your growth plan
- Reliable notifications and background work are core
- Peak performance is a competitive factor
If you land on a store app, a cross-platform approach is often the best value — we compare the options in React Native vs. Flutter vs. native, and give budget ranges in our app cost guide.
How to start: a pragmatic path
- 1
Define the core journey
Focus on the one task users must complete.
- 2
Build it as a PWA
Fast, installable, with sensible offline behaviour.
- 3
Measure real use
Installs, retention and the features people ask for.
- 4
Decide
If you hit PWA limits, wrap or rebuild as a store app using what you learned.
- Served over HTTPS with a valid manifest and icons
- Service worker caches key assets and handles offline gracefully
- Loads fast on mid-range phones (see Core Web Vitals)
- Install prompt and instructions are clear on each platform
- Notifications tested on every platform you target
- Accessible and usable with one hand on a small screen
