A web application in the context of mobile development refers to applications that run in a web browser but deliver app-like functionality — including offline capability, push notifications, home screen installation, and camera access — without requiring App Store or Play Store installation. These are formally known as Progressive Web Apps (PWAs). For Gurugram IT companies and businesses that need mobile-accessible applications but face the cost, timeline, or approval constraints of native app development, PWAs deliver 70 to 80 percent of native app functionality at 40 to 60 percent lower development cost — accessible on any device with a web browser. Garuda Technologies builds PWAs and browser-based web applications using React, Next.js, and modern Web APIs — delivering applications that install to the home screen, work offline, send push notifications, and pass Google's PWA quality criteria.
Progressive Web Apps and native apps serve overlapping but distinct use cases. Understanding the distinction prevents both over-engineering (building a native app when a PWA adequately serves the requirement) and under-engineering (deploying a PWA for a use case that genuinely requires native device integration).
Approach | Key Characteristics | Best Use Case |
Progressive Web App (PWA) | Runs in a browser. Installable to home screen without App Store/Play Store. Works offline via Service Worker caching. Push notifications on Android and desktop (iOS push notification support added in iOS 16.4). No App Store review process. Updates instantly without user action. Accessible via URL — no install barrier for new users. Lower development cost. No platform revenue sharing (Apple 15-30% applies to native in-app purchases, not PWA transactions). | Content apps, ecommerce with low hardware requirements, B2B portals, internal tools, SaaS companion apps |
Native App (Android/iOS) | Installed from Play Store or App Store. Full access to all device hardware APIs (camera with full control, GPS, Bluetooth, NFC, biometrics, ARKit, HealthKit). Better performance for animation-intensive and hardware-dependent use cases. App Store discovery channel for consumer apps. Push notifications with rich media and background delivery. Required for applications targeting Apple Pay, Android Pay, or health/fitness data. | Consumer apps with hardware integration, fintech, health and fitness, gaming, apps requiring App Store discovery |
When PWA replaces native app | When the primary requirement is mobile-accessible content, forms, or data management without deep hardware integration. When avoiding App Store review overhead is commercially important (fast iteration cycles, B2B deployment without IT approval barriers). When the target audience uses both Android and iOS and a single codebase serving both platforms is preferable to two separate native builds. When budget does not support native development cost. | SME internal tools, B2B portals, information-rich consumer apps, ecommerce catalogues |
A Service Worker is a JavaScript script that runs in the background of a browser, independent of the web page, and intercepts network requests. By caching application assets and API responses in the browser, the Service Worker enables the PWA to function when network connectivity is unavailable — displaying cached content, allowing data entry that queues for submission when connectivity returns, and serving the application shell instantly on subsequent visits without waiting for network responses. Garuda Technologies implements Service Workers using Workbox (Google's Service Worker library) for cache strategy management, background sync for queued form submissions, and precaching of critical application assets.
PWAs can send push notifications to users on Android and desktop browsers without requiring a native app install. iOS added PWA push notification support in Safari 16.4 (iOS 16.4 released March 2023), meaning PWA push notifications now reach both Android and iOS users — though iOS requires the PWA to be added to the home screen first. Push notifications are delivered through the Web Push Protocol using VAPID keys, with Firebase Cloud Messaging as the delivery infrastructure for both Android Chrome and desktop Chrome. Garuda Technologies implements web push with user permission flow optimisation, notification segmentation by user preference, and notification analytics tracking open and interaction rates.
When a PWA meets Google's installability criteria — served over HTTPS, has a valid Web App Manifest with required icons and a display mode, and has a registered Service Worker — Chrome on Android prompts the user to install the app to their home screen. The installed PWA appears as an app icon, launches in a standalone window without browser chrome (address bar and navigation controls), and behaves identically to a native app to the casual user. Garuda Technologies configures Web App Manifests with all required icon sizes, theme colours, and display modes, and validates PWA installability using Lighthouse's PWA audit criteria.
Modern web browsers expose hardware APIs that allow PWAs to access device capabilities without native code:
• Camera API (MediaDevices.getUserMedia): Photo capture, QR code scanning, and document scanning in-browser — covers most camera use cases without native development.
• Geolocation API: GPS location access in the browser — comparable to native location access for most location-aware web applications.
• Web Bluetooth and Web NFC: Experimental but increasingly supported APIs for BLE device communication and NFC tag reading in Chrome on Android.
• File System Access API: Read and write local files with user permission — enables document editing PWAs comparable to desktop applications.
• Payment Request API: Streamlined payment checkout supporting saved payment methods, Apple Pay (Safari), and Google Pay (Chrome) without a dedicated payment gateway SDK.
The gap between PWA capabilities and native app capabilities has narrowed significantly since 2020. For the majority of business application use cases, PWAs now access the device hardware features the application requires — without native development cost.
Project Type | India Pricing Range and Timeline (2026) |
Simple PWA (informational + offline + notifications) | INR 1,00,000 to INR 2,50,000. Service Worker, Web App Manifest, push notifications, offline caching. 4 to 8 weeks. |
Mid-complexity PWA with data management | INR 2,50,000 to INR 6,00,000. User authentication, IndexedDB local data, background sync, REST API integration, complex UI. 8 to 16 weeks. |
Enterprise PWA replacing a native app | INR 5,00,000 to INR 15,00,000. Offline-first data architecture, SSO, role-based access, complex forms with offline queue, performance-optimised for low-end devices. 12 to 24 weeks. |
A web application is any software that runs in a web browser — from a simple interactive calculator to a complex SaaS dashboard. A Progressive Web App is a specific category of web application that additionally meets three criteria: it is served over HTTPS, it has a Web App Manifest specifying app metadata and icons, and it has a registered Service Worker enabling offline functionality and push notifications. All PWAs are web apps; not all web apps are PWAs. The 'progressive' in the name refers to the approach of progressively enhancing a standard website with app-like capabilities rather than building a separate native application.
For 70 to 80 percent of business application use cases, a well-built PWA delivers equivalent functionality to a native app at significantly lower cost and without App Store review overhead. The cases where native apps remain necessary are specific: applications requiring Apple Pay or Android Pay integration (PWA Payment Request API covers Google Pay in Chrome but not Apple Pay in the same way), applications using HealthKit or ARKit (iOS-only native APIs with no web equivalent), applications requiring background Bluetooth LE communication, and consumer apps where App Store or Play Store discoverability is a primary acquisition channel. Garuda Technologies honestly advises whether a PWA or native app is the right choice for each specific requirement — not based on which produces a larger development contract.
Yes, with some limitations relative to Android. Safari on iOS supports Service Workers, Web App Manifests, and home screen installation. iOS 16.4 (March 2023) added Web Push notification support for PWAs added to the home screen — meaning PWA push notifications now reach iPhone users who have installed the PWA. The iOS PWA experience has historically lagged Android Chrome in feature completeness, but as of iOS 17 and iOS 18, the gap has narrowed to the point where most PWA functionality is comparable across both platforms. Garuda Technologies tests all PWA builds on both iOS Safari and Android Chrome before delivery.
