From idea and prototype to App Store and Google Play launch, one team handles product strategy, UX, engineering, testing and support, with security and performance built in. Building for a large organisation with complex systems? See our enterprise mobile app development service.
An app makes sense when it solves a repeat problem better than a website can. We help you decide before you spend.
Customers use mobile first
An app can offer faster, more personal journeys than a mobile site.
Features a browser cannot match
Push notifications, offline mode, camera, location, biometrics and wallet payments.
Staff work in the field
Apps for inspections, deliveries, sales visits and approvals, on any device.
You want ongoing engagement
Loyalty, bookings, subscriptions and in-app services.
A website is enough?
If so, we will say so and point you to website development.
Strategy, design, engineering and support for apps on every major platform.
iOS app development
Native apps in Swift and SwiftUI for iPhone and iPad, built to App Store guidelines.
Android app development
Native apps in Kotlin and Jetpack Compose across phones, tablets and a wide range of devices.
Cross-platform development
Flutter or React Native apps from one codebase, for faster delivery and lower cost across iOS and Android.
Mobile UI/UX design
Research, flows, prototypes and tested interfaces that follow platform conventions.
Backend & API development
Secure servers, databases and integrations behind your app (Node.js, Python, Laravel, .NET).
AI-powered features
Recommendations, chat assistants, document scanning and voice features added where they help users.
App modernisation & migration
Rebuild or upgrade ageing apps, move to cross-platform, or update to current OS requirements.
QA & testing
Functional, device, performance and security testing before every release.
Maintenance & support
OS updates, bug fixes, monitoring and feature releases after launch.
The right approach depends on your users, features and budget. We recommend honestly, not by default.
| Native (Swift / Kotlin) | Cross-platform (Flutter / React Native) | |
|---|---|---|
| Best for | Performance-heavy apps, advanced device features, platform-specific design | Most business, consumer and marketplace apps |
| Codebase | Separate for iOS and Android | One shared codebase |
| Speed to market | Slower | Faster |
| Cost | Higher | Lower |
| Device access | Full, immediate | Strong, with some native modules |

| Website Type | Typical Budget | Typical Timeline |
|---|---|---|
| MVP (one platform or cross-platform) | £1,000 – £8,000 | 3–6 weeks |
| Full consumer or marketplace app | £2,500 – £20,000 | 4–12 weeks |
| Enterprise or complex app | £2,000 – £8,000+ | 3–8 weeks |
| App maintenance plan | £50 – £300 / month | Ongoing |
How much does it cost to build a mobile app?
Cost depends on features, platforms, design, integrations and security needs. A focused MVP costs less than a full marketplace or fintech app. We give an itemised estimate after discovery.
How long does it take to build an app?
An MVP typically takes 3–6 weeks; a full app 4–12 weeks.
Should I build native or cross-platform?
Cross-platform (Flutter or React Native) suits most business apps and saves time and cost. Native suits apps that need top performance or advanced device features. We recommend after discovery.
Do you build for both iOS and Android?
Yes. We can build native apps for each platform, or one cross-platform app for both.
Can you take over or improve an existing app?
Yes. We audit the code, fix issues, update to current OS requirements and plan improvements or a rebuild.
Will you help publish the app?
Who owns the code and the app?
Do you provide support after launch?
Yes. Plans cover OS updates, bug fixes, monitoring, performance checks and new features.
