Overview
What is Mobile App Development?
Mobile app development, for us, means one React Native codebase shipped to both stores — and, where a web product already exists, one that shares its TypeScript types and API client instead of reimplementing them.
We handle the parts teams underestimate: offline state, push notifications, deep links, store review and over-the-air updates for changes that don't need a new binary.
Right fit if
- You already have a web product that needs a mobile companion
- Your product only really makes sense on a phone
- You want one team maintaining iOS and Android, not two
Not the right fit if
- You need a native-only feature no cross-platform framework supports
- There's no budget for App Store and Play Store review cycles
What we build
What we actually build.
Concrete examples of what Mobile App Development looks like in practice — the kind of thing a client asks for on a first call.
Companion app
A mobile app that shares types and an API client with your existing web product, instead of a separate rebuild.
E.G. the same account and billing data on web and mobile
Offline-first app
Data that syncs when the connection comes back, for users who aren't always online.
E.G. a field-service app used in areas with patchy signal
Store release pipeline
A release pipeline your team can run: builds, store submission and over-the-air updates.
E.G. a hotfix shipped without a new App Store review
How we build it
Built to be trusted. Not just demoed.
A demo takes an afternoon. Something your team relies on takes engineering — this is what that looks like in practice.
One source of truth with your web app
Types and the API client are shared, not duplicated, so the two products can't drift apart.
Sync handled, not assumed
Offline-first data handling so the app is usable before the network catches up.
Ship without a store review
Over-the-air updates cover everything that doesn't need a new binary.

FAQ
Straight answers.
Can the app share code with our existing web product?
Yes, when one exists — the mobile app shares its TypeScript types and API client with your web codebase rather than reimplementing them.
Do you handle App Store and Play Store submission?
Yes, including the review process for both stores, and an over-the-air update pipeline for changes that don't need a new binary.
What happens if the app needs to work offline?
We build offline-first data handling so the app stays usable without a connection and syncs when it comes back.
