How Progressive Web Apps Are Changing the Mobile Web — Robosoft Blog
PWAs blend the reach of the web with the feel of a native app. Here's where that trade-off actually pays off, and where it doesn't.
What a PWA actually is
A progressive web app is a website built with modern browser features — a service worker, a web app manifest, and HTTPS — that let it behave like an installed app. It runs in the browser, but users can add it to their home screen, get push notifications, and open it without a network connection.
Why it matters for load times and offline use
The service worker caches key assets ahead of time, so repeat visits load almost instantly and the app keeps working on a flaky connection. That matters more than it sounds: for content-heavy or transactional sites, a few hundred milliseconds of load time is the difference between someone staying and someone bouncing.
Where PWAs make sense
- Content and media sites that want an app-like feel without an app store
- E-commerce storefronts where speed directly affects conversion
- Internal tools used by field teams with unreliable connectivity
Where a native app still wins
Deep OS integration — background processing, certain hardware APIs, platform-specific UI conventions — is still native app territory, particularly on iOS where PWA support lags Android. For most business software and public-facing products, though, a well-built PWA covers the gap at a fraction of the cost of maintaining two native apps.
