01What we build

  • 01

    iOS development

    Native iPhone and iPad apps in Swift and SwiftUI.

  • 02

    Android development

    Native Android apps in Kotlin and Jetpack Compose.

  • 03

    Cross-platform apps

    One codebase for iOS and Android with React Native or Flutter.

  • 04

    App backends

    APIs, authentication, push notifications, payments and admin dashboards.

  • 05

    App Store optimisation

    Store listings, screenshots and release management for App Store and Google Play.

02Native or cross-platform?

Cross-platform frameworks such as React Native and Flutter are the right choice for most business apps: one codebase, faster delivery and lower maintenance. Native development makes sense for apps that rely heavily on device hardware, complex animations or the latest platform features. We advise on the best fit for your product.

03What you get

  • Mobile UX and UI design

    Screens and interactions designed for touch, small screens and the conventions of iOS and Android.

  • iOS and Android apps

    Apps built natively or cross-platform, depending on what your product needs.

  • App backend and admin panel

    APIs, authentication, push notifications and a dashboard to manage content and users.

  • In-app purchases and subscriptions

    Payments and subscriptions set up according to App Store and Google Play rules.

  • Store release

    Store listings, screenshots, privacy details and submission under your own developer accounts.

  • Crash reporting and analytics

    Insight into crashes, performance and usage from the very first release.

04Who it's for

  • 01

    Customers who want a direct channel

    A business wants customers to order, book or manage their account in an app, with push notifications for updates.

  • 02

    Staff working on the road

    Technicians or drivers register work, photos and signatures on their phone, also where the connection is poor.

  • 03

    A consumer app idea

    A founder wants to launch a subscription or community app on both platforms and validate it with real users.

  • 04

    An outdated app that needs a restart

    An existing app crashes, no longer meets store requirements or has become too hard to change.

05How we work

  1. Define the core journeys

    We pick the few flows users will repeat most and design those first, tested on real devices.

  2. Choose native or cross-platform

    Based on hardware needs, design ambitions and your existing stack, we advise Swift and Kotlin, React Native or Flutter.

  3. Agree on the API contract

    App and backend are designed against a shared, documented API, so both can be built and tested in parallel.

  4. Test on devices and with beta users

    Builds go to TestFlight and Google Play test tracks, so you and selected users can try every iteration.

  5. Release and maintain

    We handle store review and staged rollouts, and keep the app up to date for new iOS and Android versions.

07Our standards

  • 01

    Smooth performance

    Fluid scrolling and animation, quick start-up and careful use of battery and mobile data.

  • 02

09Frequently asked questions

Should I build a native or cross-platform app?

For most business apps a cross-platform app with React Native or Flutter is faster and more cost-effective. Native iOS and Android apps are better when you need deep hardware access or maximum performance.

Do you publish the app in the App Store and Google Play?

Yes. We handle the store listings, review process and releases, and can publish under your own developer accounts.

Do you maintain the app after launch?

Yes. We update apps for new iOS and Android versions, fix issues, monitor crashes and add features.

Can the app work offline?

Yes. We can store data on the device and synchronise when the connection returns, which is useful for field work and travel.

Can you also build the admin panel or a web version?

Yes. We build the backend, the admin dashboard and, if needed, a web app alongside the mobile app, so everything fits together.

How do you handle push notifications and privacy?

Users are asked for permission at a moment that makes sense, notifications can be managed per topic, and the app only collects the data it actually needs.
