Mobile usage in India has exploded, with over 800 million smartphone users in 2026. But not every business needs a native app — and not every user wants to download one. Progressive Web Apps bridge this gap by delivering app-like experiences directly through the browser, with offline support, push notifications, and home screen installation. For businesses in Salem and Tamil Nadu, PWAs offer a cost-effective path to mobile engagement without the complexity of maintaining separate iOS and Android codebases.
At Fillicore Technologies, we build PWAs that load instantly even on slow 3G connections, work reliably in offline or low-connectivity areas across Tamil Nadu, and provide the smooth, gesture-driven interactions users expect from native apps. The result is higher engagement, lower bounce rates, and significant cost savings compared to traditional native app development.
01 — Understanding PWAs
PWAs combine the reach of the web with the capabilities of native apps. Here's what sets them apart.
Service workers cache critical assets and data, enabling your PWA to function without an internet connection. Users in areas of Salem with spotty connectivity can still browse products, read content, and queue actions for sync.
Re-engage users with timely, relevant push notifications — order updates, appointment reminders, or promotional alerts. Drive repeat visits without relying on email or SMS campaigns.
Users can add your PWA to their home screen with one tap — no app store required. It launches in its own window, has a custom splash screen, and feels indistinguishable from a native app.
02 — Why PWAs
PWAs deliver 80% of native app functionality at a fraction of the cost and development time.
One codebase serves all platforms — desktop, Android, and iOS. No need to hire separate Swift and Kotlin developers. Fillicore builds your PWA once, and it runs everywhere, saving Salem businesses significant development budget.
Skip the 30% app store commission, lengthy review processes, and forced update cycles. Your PWA is always up-to-date because it's served from the web. Users access it instantly via a URL — no download required.
With service worker caching and pre-fetching strategies, PWAs load in under 1 second on repeat visits. This is critical for users in Tamil Nadu where network speeds vary widely between urban Salem and rural areas.
03 — Features
Every PWA we deliver includes these essential capabilities for a native-like experience.
Intelligent caching strategies — cache-first for static assets, network-first for dynamic content. Your PWA works reliably even when the network doesn't.
Queue user actions when offline and automatically sync when connectivity returns. Form submissions, cart updates, and data entries never get lost.
One PWA adapts seamlessly from mobile phones to tablets to desktops. Responsive layouts with adaptive features based on device capabilities and screen size.

05 — FAQ
Yes. Since iOS 11.3, Safari supports service workers and web app manifests. PWAs can be added to the home screen on iPhones and iPads, though some features like push notifications have limitations compared to Android.
For many use cases, yes. PWAs offer offline access, push notifications, camera access, and app-like navigation. Unless you need deep hardware integration like Bluetooth or NFC, a PWA can replace a native app at a fraction of the development cost.
PWAs load 2-3x faster than traditional mobile websites and are comparable to native apps in perceived performance. With service worker caching, repeat visits load almost instantly, even on slow 3G networks common in parts of Tamil Nadu.
