Mobile App Development Company
iOS and Android apps, native or cross-platform, designed, built, tested and launched on the App Store and Google Play.
Mobile App Development for UK & international businesses
A good app does one job better than a website can. It might work offline, send timely notifications, use the camera or location, or give loyal customers a faster way to buy. A poor app gets uninstalled within days. The difference comes down to focus, design and reliable engineering.
Maetheon Ltd builds mobile apps for startups and businesses in the UK, the United States, Canada and Australia. We handle the full journey: product planning, UX and UI design, development, testing, store submission and updates. We are a UK-registered company with a remote delivery team, and you work with one accountable point of contact throughout.
Most projects use a cross-platform framework (Flutter or React Native), so one codebase serves both iOS and Android. That reduces cost and keeps the two apps in step. Where an app needs deep device features or maximum performance, we recommend native development and explain why.
What we can build for you
Cross-platform apps
One Flutter or React Native codebase for iOS and Android, with a native look and feel.
Native iOS & Android

App UX & UI design
User journeys, wireframes and polished interface designs, tested before development.
Backend & APIs
Accounts, databases, admin panels and APIs that power the app and keep data secure.
Payments & subscriptions
In-app purchases, subscriptions and card payments set up to meet store rules.
