App Development

Native and cross-platform apps for iOS and Android. We've shipped apps running on millions of devices. We'll build yours to the same standard.

12+ years building mobile apps
100s App Store and Google Play submissions handled
2 platforms iOS and Android, native and cross-platform

Apps that people actually use

Building an app that works is the easy part. Building one that people download, use regularly and rely on is harder. It takes understanding your users, getting the experience right, and making sure the technology doesn't get in the way.

We've been building apps for over a decade. Consumer apps, internal tools, companion apps for larger platforms. Every one is built to feel right on the device, perform reliably and pass App Store review without surprises.

Native iOS & Android

When performance and platform-specific features matter, we build native. Full access to device capabilities, smooth animations and the experience users expect from a well-built app.

Cross-Platform

When you need to reach both platforms without doubling the budget, React Native lets us share code across iOS and Android while still delivering a native feel. One codebase, two platforms, no compromise on quality.

Companion & Internal Apps

Not every app is customer-facing. We build internal tools, field apps, companion apps for web platforms and admin interfaces. If your team needs it on a phone or tablet, we can build it.

4 million devices, 12 years.

We built and maintained the GAME app for over 12 years. At its peak it was running on 4 million devices across the UK. We handled every version, every platform update, every App Store submission for over a decade.

That kind of longevity doesn't happen by accident. It takes code that's maintainable, architecture that adapts, and a team that understands how mobile platforms evolve. We brought that same approach to every app we've built since.

From idea to App Store

Getting an app from concept to live involves more than just writing code.

Define and design

We work out what the app needs to do, design the user experience and prototype it before writing code. You'll interact with your app on a real device before development starts.

Build & Test

Together, we define the core functionality, map user journeys, and agree on what belongs in the first release. This keeps the project focused and reduces complexity.

Submit and launch

We handle App Store and Google Play submissions, review processes, provisioning and all the platform-specific requirements that catch teams out. We've been through it hundreds of times.

Support & Iterate

Apps need ongoing attention. OS updates break things, users request features, analytics reveal behaviour you didn't expect. We provide ongoing support and iteration to keep your app relevant.

Common questions

Should I build native or cross-platform?

It depends on what the app does. If you need deep hardware integration, complex animations or platform-specific features, native is the right choice. If you need to ship on both platforms efficiently and the app is primarily content and data-driven, cross-platform with React Native makes more sense. We'll recommend the right approach for your specific case.

How long does it take to build an app?

A focused MVP typically takes 2-4 months. More complex apps with backend systems, integrations and multiple user roles take longer. We'd rather ship something real quickly and iterate than spend a year building in isolation.

Can you work with our existing backend?

Yes. We regularly build apps that connect to existing APIs, platforms and data sources. If you already have a web application or backend system, we can build a mobile app that integrates with it.
