A Progressive Web App (PWA) is a website built to behave like an app — installable to a home screen, capable of working offline, and able to send push notifications, all without going through an app store. For many businesses, a well-built PWA now covers 80% of what they actually needed a "real app" for, at a fraction of the cost. This decision naturally follows on from our iOS vs Android platform guide if you've already decided native is the route.
What a Progressive Web App Actually Is
Technically, a PWA is just a website built with specific web technologies (a service worker for offline caching, a web app manifest for install behaviour) that unlock app-like capabilities inside a regular mobile browser. On Android, PWAs can be installed to the home screen with minimal friction. On iOS, support exists but is more limited — push notifications and certain install prompts behave differently than on Android, which is the single biggest caveat to know before committing to a PWA-only strategy.
Where PWAs Genuinely Compete With Native Apps
- Content and information apps — news, blogs, directories, and booking platforms that don't need deep device hardware access
- eCommerce — many retailers now run PWA storefronts successfully, since checkout and browsing don't require native-only capabilities
- MVPs and early-stage products — validating demand before investing in two full native builds
- Cross-platform reach — one codebase reaches both iOS and Android browsers, plus desktop, without app store approval delays
Where Native Apps Still Clearly Win
- Deep hardware access — Bluetooth device pairing, advanced camera controls, background location tracking
- Performance-critical apps — games, video editing, or anything needing native-level graphics performance
- Reliable push notifications on iOS — native apps have full, consistent push notification support that iOS PWAs still handle inconsistently
- App store discoverability — if being found by browsing the App Store or Play Store matters to your acquisition strategy, you need to actually be listed there
Cost Comparison
| Progressive Web App | Native App (iOS + Android) | |
|---|---|---|
| Typical build cost | $3,000 – $15,000 | $15,000 – $80,000+ |
| Codebases to maintain | One | Two (or one cross-platform) |
| App store approval needed | No | Yes, for both stores |
| iOS push notifications | Limited/inconsistent | Full support |
If you're unsure, build the PWA first. It validates demand at a fraction of native cost, and if you outgrow it, that same product logic and design can inform a native build later — nothing is wasted.
How to Decide
Ask honestly whether your product needs deep hardware access or app store discoverability specifically. If not, a PWA very likely delivers most of the value your users actually want, at a fraction of the cost and with one codebase to maintain instead of two.
Conclusion: Native apps aren't going away, but they're no longer the default first move for every business with a mobile idea. A PWA is frequently the smarter, cheaper starting point — reserve the full native investment for when a specific capability genuinely requires it.
AppsBrain builds both Progressive Web Apps and native iOS/Android apps, and can help you objectively assess which approach actually fits your product before you commit budget.
