Progressive Web Apps — Install From the Browser, Work Offline
PWAs combine the reach of the web with the capabilities of native apps. Starbucks' PWA is 99.84% smaller than their iOS app, loads in 2 seconds on slow connections, and increased daily active users by 2x. For businesses that need app-like experiences without app store gatekeeping, PWAs eliminate the install friction that kills 68% of potential mobile conversions.
The App Store Bottleneck
Getting users to install a native app is expensive. The average cost per install (CPI) exceeded $3.50 globally in 2025, and it's trending higher. 68% of users who click an app store link abandon the process before installation completes. The friction of switching to a store, waiting for a download, and granting permissions creates a conversion wall.
For many businesses, a native app is overkill. Internal dashboards, event guides, restaurant ordering, content platforms, and e-commerce catalogs don't need access to the accelerometer or ARKit. They need fast loading, offline capability, and push notifications. Building and maintaining native apps for these use cases means paying for capabilities you don't use.
Meanwhile, mobile web traffic accounts for over 60% of all web traffic, but mobile web conversion rates are half those of native apps. The gap isn't about capability — it's about experience. Mobile websites feel temporary. PWAs close that gap.
Web Technology, App-Like Experience
A Progressive Web App uses standard web technologies — HTML, CSS, JavaScript — enhanced with modern browser APIs that enable native-like behavior. Service workers cache assets and data for offline access. The Web App Manifest defines install behavior, home screen icons, and splash screens. The Push API delivers notifications even when the app isn't open.
We build PWAs with Next.js, applying server-side rendering for fast initial loads and static generation for offline-capable pages. Workbox handles caching strategies: network-first for dynamic content, cache-first for static assets. IndexedDB stores structured data locally for full offline functionality.
The result: an app that loads in under 2 seconds on 3G, installs with one tap (no store required), works offline, sends push notifications, and auto-updates without user intervention. It's indexed by search engines, shareable via URL, and runs on any device with a modern browser. The distribution advantage is massive — every link to your site is a potential install.
Our PWA Development Process
Capability Assessment(1-2 weeks)
We map your app's requirements against PWA capabilities. Identify features that work natively in the browser, those that need polyfills, and any that truly require a native app. For existing websites, we audit the current architecture for PWA readiness.
Architecture and Caching Strategy(1-2 weeks)
Define the service worker caching strategy for each resource type. Plan offline data sync patterns. Configure the web manifest for install behavior. Set up push notification infrastructure with Firebase Cloud Messaging.
Development and Offline Testing(6-12 weeks)
Next.js development with Workbox integration. Offline-first data layer with IndexedDB. Background sync for deferred operations. Testing across devices with throttled network conditions and airplane mode scenarios.
Launch and Performance Optimization(1-2 weeks)
Lighthouse audit targeting 90+ scores across all categories. Core Web Vitals optimization. Install prompt strategy (when and how to surface the install banner). Push notification opt-in flow design to maximize subscription rates without being aggressive.

Why idataweb for PWA Development
Modern Production Stack
Cross-platform apps built with React Native or Flutter share up to 90% of code between iOS and Android. Backend APIs run on Next.js 16 with Payload CMS 3 and PostgreSQL — the same production stack that powers our web applications, ensuring smooth integration.
AI-Native Team
We integrate Claude, GPT-4o, and voice AI (Deepgram, ElevenLabs) directly into mobile applications. From intelligent assistants to voice-controlled interfaces — AI features ship as native app capabilities, not bolted-on afterthoughts.
Self-Hosted Infrastructure
Backend infrastructure you fully control. No dependency on Firebase, Supabase, or other BaaS platforms that can change pricing overnight. Your data, your servers, your deployment pipeline — with full PostgreSQL audit trails.
End-to-End Delivery
From app concept and UX design through development, App Store submission, to ongoing updates — one team manages the entire lifecycle. No agency handoffs between design, development, and DevOps.
Transparent Fixed Pricing
Fixed-price milestones for each development phase: design, MVP, beta, launch. You review and approve before each phase begins. No hourly billing surprises — you know the total cost before we write a single line of code.
Frequently Asked Questions
What is a progressive web app?
A PWA is a web application enhanced with modern browser APIs to deliver app-like experiences. PWAs can be installed on home screens without an app store, work offline using service workers, send push notifications, and access device features like camera and location. They load fast, update automatically, and are discoverable through search engines. The technology has been adopted by Starbucks, Twitter, Pinterest, and hundreds of other companies.
How much does PWA development cost?
PWAs cost 50-70% less than native mobile apps. Converting an existing website into a PWA (adding service workers, manifest, offline capability) starts at $5,000-$15,000. Building a full-featured PWA from scratch with offline data sync, push notifications, and installable experience ranges from $15,000-$40,000. The long-term savings are significant: one codebase, no app store fees ($99/year Apple, $25 one-time Google), and standard web hosting.
Do PWAs work on iOS?
iOS supports PWA installation, offline caching, and most web APIs since Safari 11.3. Apple added push notification support in iOS 16.4 (March 2023) and has continued expanding capabilities. Remaining limitations: no background sync, storage caps around 50MB per origin, and no access to Bluetooth or NFC. For use cases like e-commerce, content delivery, dashboards, and internal tools, iOS PWA support is more than sufficient.
Should I build a PWA or a native app?
Build a PWA when: your app is content-driven, you need the widest possible reach, app store friction hurts conversions, or budget is limited. Build native when: you need AR/VR, advanced Bluetooth/NFC, complex background processing, or deep OS integration. Many businesses start with a PWA to validate the concept, then add native apps for specific use cases. The web codebase transfers well to React Native if you later need a native version.
Can a PWA access the camera and GPS?
Modern browsers support camera access (MediaDevices API), GPS (Geolocation API), device orientation, vibration, and WebGL for 3D graphics. The Web Authentication API enables biometric login (Face ID, fingerprint). File system access, clipboard, and share functionality are also available. The capability gap between PWAs and native apps has narrowed dramatically since 2020. We assess your specific feature requirements and confirm browser support before recommending the PWA approach.
How do PWAs handle updates?
PWAs update automatically. When you deploy a new version, the service worker detects the change and downloads updated assets in the background. Users get the latest version on their next visit without any action. There's no app store review process, no waiting for approval, and no version fragmentation across your user base. You can push critical fixes within minutes of deploying to your server.
