Frequently Asked Questions (FAQ) About PWAs and PWAMobile

1. What is a Progressive Web App (PWA)?

A Progressive Web App (PWA) is a type of web application that behaves like a native mobile app while running in a web browser. It combines the best of both worlds: the reach of a website with the performance and experience of a mobile app.

2. How does a PWA compare to a regular mobile app?

Feature	PWA	Native Mobile App
Installation	No app store needed; installs directly from the browser	Requires download from the App Store or Google Play
Storage	Uses minimal storage	Takes up significant device space
Performance	Fast and responsive with service workers	High performance but can be resource-heavy
Updates	Auto-updates without user intervention	Manual updates via the app store
Development Cost	~50% cheaper than native apps	Expensive due to platform-specific coding
Cross-Platform	Works on all devices with a browser	Needs separate versions for iOS and Android
Offline Capability	Yes, with caching via service workers	Yes, but requires additional backend work
Push Notifications	Supported on Android, limited on iOS	Fully supported on both iOS and Android

3. Why is a PWA half the price of a native mobile app?

Single Codebase: PWAs are built using standard web technologies (HTML, CSS, JavaScript) and work across all devices, reducing development costs.
No App Store Fees: No need for Apple or Google store approvals or commissions.
Lower Maintenance Costs: A single PWA update applies to all users instantly.
Faster Development: PWAs use existing web development tools, cutting development time in half.

4. Can a PWA work offline?

Yes! PWAs use service workers to cache essential assets, allowing them to work even when there is no internet connection.

5. Does a PWA require an app store for distribution?

No, a PWA can be installed directly from a website without needing an app store. This avoids delays from app store approvals and ongoing fees.

6. How does PWAMobile optimize PWA performance?

PWAMobile leverages:

Progressive Enhancement for smooth performance on all devices
Service Workers for offline functionality

Responsive Design for seamless mobile experiences

7. How secure are PWAs?

PWAs are as secure as native apps when built correctly. They use HTTPS encryption, preventing unauthorized access and data interception.

8. Can a PWA send push notifications like a mobile app?

Yes, PWAs support push notifications, but with limitations on iOS. On Android, notifications work similarly to native apps.

9. Do PWAs work on iPhones and iPads?

Yes, PWAs work on iOS and iPadOS, but with some restrictions. Push notifications were limited until recent updates in iOS 16.4+.

10. How do users install a PWA?

Visit the PWA-enabled website.
Click the “Add to Home Screen” prompt.
The PWA installs and functions like a native app.
