What does a mobile app development company do?

A mobile app development company designs, builds, tests and publishes apps for iPhone and Android, together with the back-end systems and APIs they rely on. A good partner also plans for UK GDPR, app store review requirements, security and the updates every app needs after launch.

What we deliver

Mobile App Development
services we offer.

  1. iOS & Android Apps

    Native apps for iPhone and Android when you need the best performance or deep access to device features.

  2. Cross-platform Development

    One shared codebase for iOS and Android, so you reach both platforms sooner and maintain them more efficiently.

  3. UI/UX Design

    User research, journeys and interface design that make your app easy to learn, accessible and pleasant to use.

  4. App Store Deployment

    Submission to the Apple App Store and Google Play, including store listings, privacy declarations, review requirements and release management.

How we work

How we deliver
mobile apps.

  1. Discover and validate

    We define the problem, the users and the smallest version of the app that proves the idea.

  2. Design and prototype

    User journeys and a clickable prototype you can test with real users before development starts.

  3. Build and integrate

    App development plus the back end, admin tools and integrations it needs.

  4. Test

    Testing across devices and operating system versions, covering accessibility, security and performance.

  5. Launch and iterate

    Store release, then updates, new features and operating system compatibility over time.

Built for the UK

UK requirements for
mobile apps.

  1. UK GDPR in apps

    Apps often handle location, contacts, health or payment data. You need a privacy notice, a lawful basis for each use, data minimisation and secure storage and transfer.

  2. The ICO's Children's code

    If your app is likely to be used by under-18s, the Information Commissioner's Age Appropriate Design Code sets standards for privacy settings, data collection and nudge techniques.

  3. Online Safety Act 2023

    Apps that let users share content with each other, or that include search, can have duties under the Online Safety Act. It is worth assessing early if your app has community features.

  4. Payments and Strong Customer Authentication

    Taking card payments in the UK means working with regulated payment providers and supporting Strong Customer Authentication in your checkout flow.

  5. App store privacy declarations

    Both Apple's App Privacy details and Google Play's Data safety section must accurately describe the data your app collects. We prepare these with you.

Pricing

What affects
the cost?

App budgets depend far more on scope than on the platform. The main cost drivers are:

  1. iOS, Android or both
  2. Native versus cross-platform development
  3. Number and complexity of features
  4. Back end, admin dashboard and integrations
  5. Design depth and user research
  6. Maintenance, hosting and operating system updates after launch

FAQ

Mobile App Development
questions, answered.

How much does it cost to build an app in the UK?

The cost depends on the platforms, features, back end and design depth. A focused first version (MVP) costs much less than a feature-rich app with complex integrations. We scope your app first, then give you an estimate in pounds, with VAT shown separately.

Should I build a native or a cross-platform app?

Cross-platform development suits most business apps: one codebase serves iOS and Android, which saves time and maintenance. Native development makes sense when you need maximum performance, advanced device features or platform-specific experiences. We recommend an approach once we understand your requirements.

How long does it take to develop an app?

As a rough guide, a focused first release often takes around 3–6 months, depending on features, integrations and testing. Apps with complex back ends or regulated data take longer. We agree milestones up front so you can see progress throughout.

Who owns the app and the app store listing?

You should. We recommend publishing under your own Apple Developer and Google Play accounts, so your business owns the listings, reviews and customer relationship. We handle the build, submission and releases for you.

Do you build the back end and admin system as well?

Yes. Most apps need APIs, databases, user management and an admin dashboard. We build and integrate these alongside the app, including connections to your CRM, ERP or website where needed.

What happens after my app is launched?

Apps need ongoing care: fixes, security updates, new operating system versions and new features based on user feedback. We offer ongoing support so your app keeps working and improving after launch.
