Web App Development King's Lynn — Custom Built Applications

Custom web apps, mobile apps & bespoke software for businesses in King's Lynn and Norfolk. Booking systems, CRMs, dashboards and more.

Custom Software for King's Lynn Businesses

Sometimes a standard website isn't enough. If your King's Lynn business needs a mobile app, a booking system, a customer management tool, an internal dashboard or any kind of custom software — we build it. As a local web app developer, we understand the unique needs of Norfolk businesses and deliver solutions that actually work.

At Website and Design, we develop bespoke web applications and mobile apps that solve real business problems. We've built booking platforms, holiday letting systems, customer portals and more — all from our base in King's Lynn.

We use modern frameworks and technologies to build fast, reliable, secure applications that work on any device. Whether you need to replace spreadsheets, automate processes, build custom software or create something entirely new, our web app development team can help.

Mobile App Design & Development

Not every business needs a native app on the App Store. We specialise in building mobile-responsive web apps and progressive web apps (PWAs) that look and feel like native mobile apps — without the cost and complexity of separate iOS and Android development.

Our mobile app solutions are perfect for King's Lynn businesses that need their team or customers to access tools on the go. From booking apps for salons to job management tools for tradespeople, we design mobile experiences that are fast, intuitive and built to convert.
