Mobile App Development
From an initial idea to an app people actually want to use, ExtraDigital designs, develops and supports mobile applications built around your users and your business.
- Discovery, UX and prototyping
- iOS, Android and cross-platform
- Backend systems, APIs and integrations
- Launch, analytics and ongoing development
Business first
Mobile apps built around a business problem
A successful app starts with a clear reason to exist: a process to simplify, a customer to serve better, or a revenue stream to open up.
We support the whole journey, so strategy, design and engineering stay joined up rather than being handed between suppliers.
- Discovery and requirements
- UX and prototyping
- Interface design
- App and backend development
- APIs and integrations
- Testing and launch
- Analytics and continuous development
An honest starting point
Do you actually need an app?
We will not recommend building an app simply because it has been asked for. First we understand the objective, the users and how they will use it.
Then we decide whether a native app, a cross-platform app, a web application or a mobile website is the best commercial approach. Sometimes the right answer is not an app at all, and we will say so.
Native app
Deep device features, offline use, the best possible performance.
Cross-platform app
One codebase for iOS and Android, faster to market.
Web application
Complex functionality in the browser, no app store required.
Mobile website
Reach and search visibility for content-led journeys.

What we deliver
Everything an app needs to succeed
iOS and Android
Apps for both major platforms, built to each store's standards.
Cross-platform
Shared codebases where appropriate, reducing cost and time to market.
App UX and prototyping
Clickable prototypes tested before development, so the right thing gets built.
Backend systems
Secure, scalable backends and admin tools that power the app.
APIs and integrations
Connect the app to your CRM, ecommerce, bookings or internal systems.
Analytics
Measurement of usage, retention and conversion from day one.
Ongoing development
Updates, OS compatibility, security and new features over time.
Product thinking
Experience in UX, CRO and marketing helps the app get used, not just launched.
Connected systems
Connecting your app to the rest of your business
The app is often the visible part of a bigger system. We design the backend and integrations so data flows between the app and the tools your team already uses.
- CRM
- Payments
- Bookings
- Ecommerce
- User accounts
- Notifications
- Analytics
- Internal systems

How we build
Faster delivery without cutting corners
AI does not replace our developers. It helps them spend less time on repetitive work and more time on the decisions that matter: architecture, security, performance and the experience your users get.

Proven technologies
Established frameworks, platforms, APIs and components chosen first, so bespoke work goes where it adds value.
AI-assisted development
Modern tools that speed up routine work, testing and documentation, always reviewed by our developers.
Efficient, high-quality delivery
Shorter timescales and better value, with no compromise on quality, security or scalability.
Frequently asked questions
Should we build a native app or a cross-platform app?
It depends on what the app needs to do. Cross-platform development is often the most cost-effective way to reach iOS and Android with one codebase. Native development can be the better choice where an app relies heavily on device features or demanding performance. We recommend an approach once we understand the requirement.
Do we definitely need an app?
Not always. Sometimes a web application or a well-built mobile website will meet the objective faster and at lower cost. We will tell you honestly which option makes most commercial sense.
Can the app connect to our existing systems?
Yes. We regularly build APIs and integrations that connect apps to CRMs, ecommerce platforms, booking systems, payment providers and internal databases.
Do you help with App Store and Google Play submission?
Yes. We prepare builds, handle the submission process and deal with any review feedback so the launch runs smoothly.
What happens after launch?
We offer ongoing support covering operating system updates, security, bug fixes and new features, guided by analytics and user feedback.
How much does an app cost?
Cost depends on scope, integrations and platforms. A short discovery phase lets us give you a realistic estimate, and often identifies a smaller first release that proves the idea before further investment.
