Mobile Apps

Apps that feel native because they behave native. We ship iOS and Android that respect platform conventions, survive a bad connection, and get through review without drama.

Mobile punishes assumptions. A flow that works on a desk-bound laptop meets a commuter on a train with two bars of signal, a cracked mid-range Android, and eleven seconds of patience. Offline behaviour, background sync, and battery cost are product decisions, not implementation details.


We decide native versus cross-platform based on what the app actually does. Heavy device integration — camera, Bluetooth, background location — usually earns native. A content and forms product shared across both platforms usually does not. We will tell you which one you are, including when the honest answer is that you do not need an app at all.


Release process matters as much as the code. We set up signing, staged rollouts, crash reporting, and store metadata early, so shipping an update is routine rather than an event.

What this includes

  • /Native iOS (Swift) and Android (Kotlin) development
  • /Cross-platform builds in React Native or Flutter
  • /Offline-first data sync and conflict handling
  • /Push notifications and deep linking
  • /App Store and Play Store submission and review support
  • /Crash reporting, analytics, and staged rollouts

When teams call us

  • /A first mobile product alongside an existing web platform
  • /An app with poor ratings that needs a rebuild, not a patch
  • /Device features, camera, BLE, location, done properly
  • /A React Native codebase that has outgrown its foundations
  • /Release engineering that has become a bottleneck
// what we build with

We start from what the app has to do on the device, then pick the stack. Both native and cross-platform are first-class here.

Frontend Development

Accessible, performant interfaces in modern frameworks, pixel-accurate, maintainable, and fast on real devices.

Backend Development

The part nobody sees until it fails. We build APIs and services that stay correct under load, survive their own history, and can be reasoned about at three in the morning.

Quality Assurance

Testing that runs every sprint instead of the week before launch. We build the safety net that lets a team ship on Friday without holding its breath.

Common questions

Should we build a native or cross-platform mobile app?+

It depends on what the app needs to do. Apps with heavy device integration, background processing, Bluetooth, or location requirements may benefit from native development. For many product and content-driven apps, Flutter or React Native can deliver both platforms efficiently.

Do you develop apps for both iOS and Android?+

Yes. We build native iOS and Android applications as well as cross-platform apps using technologies such as Flutter and React Native.

Can you take over an existing mobile app?+

Yes. We can review an existing codebase, identify technical and product issues, stabilize releases, improve performance, or gradually rebuild areas that have outgrown their foundations.

Can you integrate device features such as camera, Bluetooth, and location?+

Yes. We work with device capabilities including cameras, Bluetooth, location services, push notifications, deep links, background tasks, and offline data synchronization.

Do you handle App Store and Google Play releases?+

Yes. We can set up signing, store configuration, staged releases, crash reporting, and submission workflows, and support the review process for both stores.

Do you provide ongoing mobile app development and support?+

Yes. After launch, we can continue with new features, OS compatibility updates, performance improvements, monitoring, bug fixes, and regular releases.
