The choice between Progressive Web Apps (PWAs) and native mobile apps significantly impacts development costs, time-to-market, and user experience. Understanding the strengths and limitations of each approach is crucial for making the right decision for your business.
What Are PWAs and Native Apps?
Progressive Web Apps (PWAs)
Definition:
- Web applications that behave like native apps
- Built with web technologies (HTML, CSS, JavaScript)
- Accessed through web browsers
- Can be "installed" on home screen
- Work offline with service workers
- Single codebase for all platforms
Examples:
- Twitter Lite
- Starbucks
- Spotify Web Player
- Uber
Native Mobile Apps
Definition:
- Platform-specific applications
- Built with native technologies (Swift/Kotlin)

});
// Notify user of update
navigator.serviceWorker.addEventListener(
'controllerchange',
() => {
window.location.reload();
}
);
