iOS / Android app

A mobile app isn't "a website in a wrapper" — it's a separate product with its own economics, architecture and store rules. So the approach differs too: we start with research and a prototype, design an architecture with headroom for growing load, and build the back end and the API.
We choose the stack to fit the task, not the trend: where peak performance matters we go native, where time to market matters more we go cross-platform. We take the app through App Store and Google Play review and set up analytics, push notifications, payments and the update mechanism.
The source code, documentation and infrastructure stay with you — you're not tied to a contractor.
