Newton Byte designs and builds progressive web apps (PWAs) for UK businesses. A PWA is a website that behaves like an app: it loads fast, works offline, can be added to the home screen and can send push notifications, all without going through an app store.
You get one codebase that works on phones, tablets and desktops, at a fraction of the cost of separate native apps.
Trusted by startups, SMEs, and enterprise brands across the UK.
Progressive web apps combine the reach of the web with the experience of a native app. Customers find you through search, open you in a browser and can install your app with a tap. There is no app store approval, no separate iOS and Android builds and no forced updates.
Progressive web apps are a strong choice for ecommerce stores, booking systems, customer portals, field-team tools and content-heavy sites. If you want app-like features but cannot justify the cost of two native apps, a PWA is often the best route.
Google’s web.dev guide to PWAs explains the technology in detail. We follow these recommendations so your app meets browser installability requirements.
Faster loading keeps visitors on the page and makes them more likely to buy or enquire. Home-screen installation puts your brand one tap away, and notifications let you remind customers about orders, bookings and offers. Because there is only one codebase, new features reach every user at the same time, with no waiting for store approval and no users stuck on old versions.
For internal tools, offline support means field staff can keep working in basements, warehouses and rural areas, with data syncing automatically once they are back online.
We handle everything from planning and design to development, testing and launch.
We build with modern frameworks such as React, Vue and Next.js, alongside service workers, web app manifests and secure APIs. The exact stack depends on your existing systems and the skills of any in-house team who will maintain the app.
We design touch-friendly, app-style interfaces that feel natural on phones while still working well on desktop screens.
Every screen is tested for accessibility, including contrast, text size and keyboard navigation.
Service workers cache key pages and data, so your app loads fast and keeps working with poor signal. Changes sync when the connection returns.
We measure Core Web Vitals before and after launch, so you can see the improvement in loading speed.
We set up web push for order updates, reminders and offers, with clear opt-in and simple controls for users.
Notifications can be segmented by user behaviour, so people only receive messages that are relevant to them.
Already have a website? We can add PWA features to it, including install prompts, offline caching and notifications, without a full rebuild.
This is often the quickest way to give customers an app-like experience while keeping your current content and search rankings.
We connect your app to payment gateways, CRMs, booking engines and databases through secure APIs. See our backend development service.
Data is exchanged securely and only the information needed for each feature is stored on the device.
We offer our full-fledged ecommerce solutions to major businesses operating in various industries. Therefore, be it is startups or enterprises, we know the needs of custom online stores. So, if you are into retail, finance, manufacturing, logistics, or any other business, we are here to help you out.
Our team covers design, frontend, backend and SEO, so your app is fast, usable and easy to find.
Need a native app instead? Our app development team builds for iOS and Android, and our frontend development team can modernise your existing site.
Native apps still make sense when you need deep device features, heavy offline processing or a presence in the app stores. For most businesses that want speed, reach and lower costs, a PWA delivers most of the benefits for much less.
A clear process keeps your project on time and on budget.
We agree goals, users, features and which tasks must work offline.
We create app-style screens and test them on real devices.
We develop the app, service worker, manifest and integrations.
We test on iPhone, Android and desktop browsers, including offline mode and installation.
We launch, measure usage and keep improving based on what your users do.
We track installs, engagement and performance, and suggest improvements each month. Browser support for new features changes regularly, so we keep your app up to date.
