React Native App Development
Cross-platform iOS and Android apps built with React Native and TypeScript, sharing skills and code with your web product.
Why choose React Native?
React Native lets developers build real native mobile apps with JavaScript or TypeScript and React. If your web product already uses React, your mobile app can share knowledge, patterns and sometimes code with it, which speeds up development and simplifies hiring.
Maetheon Ltd builds React Native apps for startups and businesses in the UK, the US, Canada and Australia, often using Expo to speed up development, testing and over-the-air updates.
We're a UK-registered company with a remote development team, handling design, build, backend, testing and store submission, so you have one partner from idea to launch.

React Native suits you if you…

- Need frequent updates
- Plan to hire JavaScript developers later
Planning a React Native project
Expo or bare workflow
Expo speeds up development and updates for most apps. Some projects need custom native modules, which the bare workflow handles more easily. We recommend the right setup for your features.
Sharing code with the web
Business logic, API clients, types and validation can often be shared between your React web app and your mobile app, reducing duplicate work and bugs.
Keeping up with upgrades
React Native evolves quickly. Regular, planned upgrades are much cheaper than letting an app fall several versions behind, so we build them into maintenance plans.

Discovery
Goals, users and first-release features.
Design
Prototypes for the key user journeys.
