What Is a PWA? Progressive Web Apps Explained Simply
A website that acts like an app. No app store required. Here's what PWAs are, when they make sense, and when you still need a native app.
You want an app for your business. But building native iOS and Android apps costs $50,000-150,000+. There might be a better option: a Progressive Web App (PWA).
What Is a PWA?
A Progressive Web App is a website that can be "installed" on your phone like an app. It gets its own icon on your home screen, opens in full screen (no browser bar), and can work offline.
Think of it as: Website + App capabilities = PWA
You've probably used PWAs without realizing it. Twitter, Pinterest, Starbucks, and Spotify all have PWA versions.
PWA vs Native App vs Website
| Feature | Website | PWA | Native App |
|---|---|---|---|
| Home screen icon | |||
| Works offline | |||
| Push notifications | |||
| App store required | No | No | Yes |
| App store fees | None | None | 15-30% |
| Full device access | Limited | Partial | Full |
| Development cost | $ | $$ | $$$ |
| Update process | Instant | Instant | App store review |
Key PWA Features
Installable
Users can add it to their home screen. Opens like a native app without the browser chrome.
Offline Support
Key content and features work without internet. Great for spotty connections.
Push Notifications
Re-engage users with notifications, just like native apps (with user permission).
Fast Loading
Service workers cache resources. Subsequent visits load instantly.
When to Choose a PWA
A PWA is a great choice when:
- You have a website and want app-like features without building two native apps
- Your audience is price-sensitive about downloading apps (common in e-commerce)
- You want to avoid the 15-30% app store commission on transactions
- You need instant updates without app store approval delays
- Budget is limited and you need to reach both platforms
- SEO matters (PWAs are indexable by Google)
When You Still Need a Native App
Go native when you need:
- Advanced device features — Bluetooth, NFC, advanced camera controls, HealthKit/Google Fit
- Heavy performance — Games, video editing, complex animations
- App Store presence — Discovery through App Store/Play Store matters
- In-app purchases — Subscriptions that use Apple/Google billing
- iOS push notifications at scale — Safari PWA support is improving but still limited
PWA Development Cost
Converting an existing website to a PWA:
- Basic PWA features: $2,000-5,000 (installable, offline caching)
- Full PWA: $5,000-15,000 (push notifications, advanced offline, app-like navigation)
Building a new PWA from scratch:
- Simple PWA: $10,000-25,000
- Complex PWA: $25,000-60,000
Compare that to native apps at $50,000-150,000+ for both platforms. PWAs are often 30-50% cheaper.
Real-World PWA Examples
Starbucks
PWA is 99.84% smaller than the iOS app. Works offline for browsing menu.
PWA increased engagement by 60% and ad revenue by 44%.
Twitter Lite
PWA reduced data usage by 70% and increased tweets sent by 75%.
HalalHQ
Our own platform has PWA features—installable, offline menu caching, push notifications.
The Verdict
For most businesses, a PWA is the smart first step before investing in native apps. You get 80% of the benefits at 30-50% of the cost.
Start with a PWA. If you outgrow it or need native-specific features, you can always add native apps later—and the PWA investment isn't wasted (the web app still serves users who don't want to download).
