Product engineering
Mobile apps
Cross-platform iOS and Android apps that share a codebase and a backend with your web product.
What we deliver
We build cross-platform mobile apps with React Native and Expo, sharing types, logic and backend with your web product, from design through App Store and Google Play release.
No public case study yet · see how an engagement runsOur approach
One TypeScript codebase for iOS and Android with React Native and Expo, native modules where performance or device features demand them, and a backend and design system shared with your web app.
We plan for the parts that are easy to underestimate: offline states, push notifications, deep links, app-store review and release management.
Straight talk
Mobile is a capability we offer rather than a showcase: we don't yet have a public mobile case study to point to, so this page shows how an engagement typically runs instead. If mobile is central to your product, we'll walk you through the approach and introduce the engineers who would do the work.

FAQ
Mobile apps: common questions
Cross-platform with React Native and Expo suits most business apps and halves the code to maintain. We recommend fully native development when an app depends on heavy graphics, advanced camera or audio processing, or platform features that cross-platform tools don't expose well.
