Design is more than how things look. It is how your customers feel when they use your website or app. Our UI/UX and design services help UK businesses create clear, attractive and easy-to-use digital products that people enjoy and come back to.
We support clients with UI/UX and design from first idea through to launch and beyond.
Trusted by startups, SMEs, and enterprise brands across the UK.











UI (user interface) design is the look of your product: colours, fonts, buttons and layouts. UX (user experience) design is how it works: how easily people find what they need and complete tasks like booking, buying or signing up.
Good UI/UX and design builds trust, reduces drop-offs and increases sales. Poor design does the opposite, even if your product is great. That is why we design around real users, not guesswork.
Newton Byte offers complete UI/UX and design support, from research and wireframes to polished visuals, brand identity and graphics for marketing.
We design websites, apps and dashboards that are simple to use and pleasant to look at, using user research, wireframes, prototypes and testing.
Your visuals tell your story before your words do. We design social media graphics, ads, brochures and presentations that look professional and stay on brand. See our graphic design service.
A brand identity is your logo, colours, fonts and voice working together. We create identities that make your business memorable and consistent everywhere. See brand identity.
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.
We focus on what matters to you: products your customers enjoy using and designs that support your business goals. Our designers work closely with our developers, so what you approve is exactly what gets built. We follow established usability principles, such as the 10 usability heuristics from Nielsen Norman Group.
Design is central to everything we build. We start with research to understand your users, then create wireframes, design the visuals, build an interactive prototype and test it with real people before development begins. This saves time and money and leads to better results.
