Your users want a fast, installable app. We build it in 6 weeks.
Redefine builds progressive web apps that load in under a second, work offline, and install to the home screen. No app store. No native SDK. One codebase for every device.
Your team commits 2 to 3 hours per week. We handle architecture, service workers, testing, and deployment. You review. You sign off. That's it.
Core Web Vitals
Your mobile app is losing customers every day
Slow loads kill conversions. App store delays slow your team. And maintaining two native codebases drains your budget before you ship a single feature.
52% of mobile users leave a site that takes more than 3 seconds to load. That's revenue you never see. (Source: Google, 2023)
Two separate codebases for iOS and Android. Two teams, two budgets, two bug queues.
App store approval takes 3 to 14 days. A broken update means rolling back and waiting again.
No network connection, no content. Customers in a dead zone get a blank screen.
Push notifications require a native permission flow and a separate notification server.
One codebase covers iOS, Android, and desktop. Ship once, update instantly, reach everyone.
Push a fix in minutes. No approval queue. Your service worker updates in the background.
Pages load in under a second on repeat visits. Your app shell is cached on the first visit.
Your app stays usable with no internet connection. Field teams, warehouses, and travelers stay productive.
Web Push API handles notifications without a native SDK. No extra server cost.
A slow mobile experience is a silent revenue drain.

Phase 01 • Discovery and Audit
We audit what you have and scope what you need.
We review your existing site or app for performance gaps, offline readiness, and PWA compatibility. You receive a written audit and a fixed-price proposal. No code starts until you sign off.
You receive: Audit document • Fixed-price proposal • Architecture diagram
Phase 02 • Architecture and Design
Caching strategy. App shell design. Push setup.
We map your caching strategy, design the app shell, configure the web manifest, and set up push notification infrastructure. You review design screens before any development begins.

Phase 03 • Core Build
Service worker. Offline cache. Push notifications. Install prompt.
Full PWA stack: service worker with cache strategies, background sync, push notification hooks, install prompt logic, and your API layer. You see working software on weekly demo calls. No slide decks.
You receive: Weekly sprint demos • staging URL • dev branch access
Phase 04 • Quality Assurance and Lighthouse
We ship only when Lighthouse scores 90 or above.
We test every page, every device, and every network condition. Automated Playwright tests plus manual testing on real iOS and Android hardware. If the score drops below 90, we fix it before launch.

Phase 05 • Deploy and Handover
Live. Documented. Yours to run.
CI/CD pipeline, deployment to your infrastructure or CDN, and a complete handover package. You receive the code, the docs, and a 30-minute walkthrough call. No lock-in.
You receive: Full source code • CI/CD config • Handover walkthrough call
Every native capability. None of the native cost.
A Redefine PWA is not a thin wrapper. It is a full-stack web experience with the same capabilities as native apps, built to production standards. No app store tax. No dual-platform maintenance bill.
Offline-first architecture
Your app works with no network connection. We cache content through a service worker using the right strategy per resource: cache-first for assets, network-first for live data. Users in dead zones stay productive.
Push notifications
Reach users even when your app is closed. Web Push API with full subscription management, audience segmentation, and iOS 16.4+ support built in. No separate notification server. No native SDK fee.
Installable to the home screen
Custom install prompt with your branding. No app store required. Installs in one tap. Runs full screen in standalone mode, exactly like a native app, on any device.
Sub-second performance
App shell loads from cache on repeat visits. Pages feel instant. We target LCP under 1.5 seconds and a Lighthouse score of 90 or above. All scores are measured on real devices.
Secure, integrated, and built to scale
HTTPS enforced across every route. Background sync queues offline actions until connectivity returns. Full REST or GraphQL API integration. Auth flows, protected routes, and role-based access built to production standards.

Browser / Device
Your PWA runs in any modern browser with no download required. On iOS and Android, users install it directly from Safari or Chrome. It launches in standalone mode with your splash screen and app icon. No app store. No waiting for review.
A real project. A real team. Real numbers.
What they do
A real estate platform that shows property listings and agent profiles. Built to serve buyers and sellers on iOS and Android, with a focus on mobile engagement.
The problem
The platform had no dedicated mobile app. Listings and agent details were browser-only. The team needed a cross-platform solution with a custom scanning feature, secure payment processing, and app store approval for iOS and Android, without building and maintaining two separate native codebases.
How we solved it
We built a cross-platform application from a single shared codebase. Features included listing browsing, agent profiles, and a custom scanning interaction. We integrated secure payments, added push notifications, and handled full app store submission for both iOS and Android.
Result
More user engagement and platform visibility within 60 days of launch on iOS and Android
What most PWA agencies get wrong
Common mistake
Treating the service worker as an afterthought
Most teams bolt on a basic cache call at the end of the project and call it a PWA. That approach breaks on updates, ignores background sync, and skips offline data flow entirely. We architect the service worker from day one.
Common mistake
Testing only on desktop emulators
Offline mode on a real iPhone with Safari behaves differently than Chrome DevTools shows. We test on physical iOS and Android devices, not simulated environments, before every launch.
Common mistake
Skipping the performance budget
A PWA that scores 58 on Lighthouse is a slow website with a manifest file. Performance is architecture, not a final pass. We build for a Lighthouse score of 90+ from the first sprint.

What buyers ask before they sign
Most PWA projects ship in 6 to 12 weeks from a signed scope. A focused MVP with offline mode, push notifications, and an install prompt is typically 6 to 8 weeks. Enterprise builds with third-party integrations, auth flows, and complex API layers add 2 to 4 weeks.
Yes. Modern iOS Safari supports service workers, install prompts, and offline caching. Push notifications on iOS require iOS 16.4 or later, with the web app added to the home screen. We build and test on real iOS and Android devices for every project we ship.
A PWA runs in the browser and installs to the device home screen without going through an app store. Native apps are compiled per platform and distributed via the App Store or Google Play. PWAs ship faster, cost less to maintain across platforms, and reach users on any device with a modern browser.
Yes. A PWA is a web app, fully crawlable and indexable by Google. Faster load times and stronger Core Web Vitals scores typically improve organic rankings. We follow Google's PWA best practices and test for crawlability before every launch.
A focused PWA with offline mode, push notifications, and an install prompt starts at $18,000 to $28,000. Enterprise builds with advanced integrations, auth flows, API layers, and custom caching strategies range from $40,000 to $80,000. Every project is scoped line by line before work starts.

Choose a PWA when these situations fit your project
Good Fit
You want a mobile app but can't justify building and maintaining two separate native codebases.
Your site loads slowly on mobile and that slowness is costing you conversions.
You need push notifications but don't want to pay for native push infrastructure.
Your users work in low-connectivity settings: field teams, warehouses, or frequent travelers.
Speed to market matters. A PWA ships in 6 to 8 weeks. A native app takes 5 to 9 months.
Not the Right Tool
You need deep hardware access: Bluetooth, NFC, complex camera pipelines, or ARKit.
App store presence is a strategic requirement. You need App Store browsing and ratings for organic discovery.
Your product needs heavy background processing like GPS tracking or audio recording that web APIs don't fully support yet.
