You know your mobile users need a better experience - but the cost of building, maintaining, and updating separate iOS and Android apps, navigating App Store reviews, and convincing users to actually download something is slowing you down and eating your budget. Progressive Web Apps load instantly, work offline, send push notifications, and install directly from the browser - no App Store, no download barrier, no separate mobile development budget. At Brainspack, we build PWAs that genuinely feel like native apps to your users, perform reliably on slow connections, and are a fraction of the cost to maintain. And we stay with you long after launch to make sure they keep performing that way.
Every PWA we build exists because a business had a specific mobile problem that a native app was either too expensive, too slow, or too high-friction to solve. PWAs aren't a compromise - for many use cases, they're the right answer.
A PWA that looks like a website on mobile isn't a PWA - it's a website. The experience has to feel app-like: full-screen, gesture-friendly, fast-loading, and visually consistent across devices. We design and build PWAs from the ground up with app-like interfaces, smooth navigation, and performance optimised for the real mobile conditions your users are in - not just a fast Wi-Fi connection in a developer's office.
Users on slow or intermittent connections - and there are more of them than your analytics suggest - abandon apps and websites that don't respond. We implement Service Workers and intelligent caching strategies that keep your PWA functional even when the network isn't. Core content loads from cache, actions queue for when connectivity returns, and users never see a blank screen because of a dropped signal.
You're losing repeat visits because you have no way to bring users back without email or paid ads. PWA push notifications reach your users on mobile and desktop, without requiring a native app installation, and with significantly higher open rates than email. We implement push notification systems that are useful to users - not spam - with proper permission flows that don't destroy opt-in rates.
The barrier between a user visiting your site and having your icon on their home screen should be a single tap. We implement the Web App Manifest and installation prompts correctly - triggering at the right moment in the user journey, with a compelling install experience that doesn't disrupt the flow for users who don't want it.
A PWA that scores 95 on Lighthouse in development but loads slowly on a mid-range Android device in real network conditions isn't actually fast. We optimise for real-world performance: efficient asset loading, code splitting, image optimisation, critical CSS inlining, and server-side rendering where it makes a measurable difference. Your users get a fast experience on the devices and connections they actually have.
If you already have a web application that's slow on mobile, has no offline support, and isn't installable - you might not need a rebuild. We conduct a full PWA audit: Lighthouse scores, Service Worker assessment, manifest review, performance profiling, and offline capability testing. In many cases, targeted improvements to an existing site can deliver a full PWA experience without starting from scratch.
PWAs are built on web standards, but the implementation quality varies enormously. We build with React, Next.js, Angular, and Vue for the frontend framework - selected based on your specific requirements and existing stack. Service Workers are implemented using Workbox for reliable caching and offline strategies. We use Vite for fast builds, Firebase for backend services and push notifications, Sentry for error monitoring, and Algolia for search where required. Every tool is chosen deliberately and documented fully.
Too many PWA projects fail not because the technology doesn't work, but because the problem wasn't properly defined, the data wasn't ready, or the solution was built in isolation from the people who'd actually use it. Our process is built to avoid all three.
We define offline needs, performance goals, notifications, and installation before development begins. PWAs require a different approach than standard web builds.
App-like interfaces optimised for mobile-first use - full-screen layouts, touch-friendly interactions, and consistency across the device spectrum your users actually own.
Standards-compliant Service Worker implementation, proper manifest configuration, performance-first code - with weekly updates and direct access to your project lead.
Testing on real devices across a range of connection speeds, not just fast Wi-Fi. Lighthouse auditing, offline scenario testing, and installation flow verification across iOS and Android.
Service Worker updates, push notification management, performance monitoring, and ongoing optimisation. PWA standards evolve - we keep your implementation current.
Deploy updates instantly without App Store review cycles. Changes go live the moment you push them
We test your PWA's offline behaviour under real network conditions - including the slow 3G connections a significant portion of your users are on.
Clean code, full documentation, and handover training. No dependency on our ongoing involvement to keep your PWA running.
Users install your PWA in one tap from the browser - no App Store account, no storage concern, no download wait. Acquisition friction drops significantly.
Web, mobile, and desktop from a single PWA - no separate iOS and Android development budgets.
