Web and mobile app development

We build web applications and iOS and Android apps that share one back end and one team, so features reach every platform together. You get apps that feel at home on each device and a codebase that stays manageable as the product grows.

What it is and when it fits.

Our default for mobile is React Native with Expo, which gives one TypeScript codebase for iOS and Android, over-the-air updates and fast release cycles. When a feature needs deeper platform access, such as Bluetooth hardware, background processing or advanced camera work, we write native modules in Swift or Kotlin. Web applications are built in React and Next.js, sharing APIs, types and business logic with the mobile apps wherever that makes sense.

This approach suits products that need to be on phones and in the browser, field and workforce apps, and consumer or B2B apps where speed of iteration matters. Fully native development is the better choice for graphics-heavy games or apps built around a single platform's newest features. If a responsive web app covers what your users need, we will recommend starting there and adding mobile later.

What we build.

How it works.

  1. 01

    Define the product

    We agree the core user journeys, target platforms and technical constraints, and decide what belongs in the first release.

  2. 02

    Design for each platform

    Interfaces follow iOS and Android conventions and your brand, and are tested on real devices before we build them.

  3. 03

    Build and test

    Development runs in short cycles with test builds on your phone, automated tests and crash reporting from the start.

  4. 04

    Release and maintain

    We publish to the stores, monitor stability and keep the apps current with new operating system versions.
