EllaByte is a boutique iOS app development and web design studio based in Cambridgeshire, United Kingdom. We specialise in creating custom iPhone and iPad apps alongside bespoke, responsive websites — all built to feel intuitive, fast, and delightful.
We sweat the small stuff — from pixel-perfect layouts to silky-smooth animations — because we believe the details are what separate good software from truly great software. Every project starts with a deep understanding of the user and ends with something we're proud to put our name on.
Our iOS apps are built natively with Swift and SwiftUI, following Apple's Human Interface Guidelines for the best possible experience on iPhone and iPad. Our websites are hand-crafted with clean, semantic HTML, modern CSS, and a relentless focus on performance, accessibility, and responsive design.
We'd rather ship one exceptional app than ten mediocre ones.
Your data stays on your device. We don't sell you to advertisers.
Native iOS code for the best possible performance and battery life.
Responsive, accessible websites that load fast and look great on every device.
