Mobile App Development Company in UK

Costs range from approximately £2,000–£5,000 for a focused MVP, £8,000–£12,000 for a startup-grade app, £15,000–£25,000 for a mid-level application, and £45,000–£80,000+ for an enterprise mobile platform. The actual cost for your project depends on platform choice, feature complexity, backend requirements, design ambition, and any regulatory compliance scope.

A simple MVP takes 3 - 4 weeks. A startup app with polished UX and a proper backend takes 5-8 weeks. Mid-level and enterprise apps typically take 3 - 6 months. These timelines assume a clean discovery process, available stakeholder time for reviews and approvals, and no major scope changes mid-project.

Both are strong cross-platform frameworks. Flutter typically delivers better visual consistency and runtime performance, particularly for consumer-facing products. React Native suits teams with existing JavaScript expertise and projects requiring deep web-mobile code sharing. Read our native apps vs hybrid apps guide for a fuller comparison.

Yes. GDPR compliance is standard in every mobile application we build for UK clients — not an optional add-on. This includes consent management, data minimisation by design, right-to-erasure support, UK/EU data residency where required, and access logging.

Yes. We have experience with NHS API integration, NHS login, HL7 FHIR R4 data exchange, and the DTAC (Digital Technology Assessment Criteria) assessment process. NHS-aware mobile development requires specific technical knowledge that not all agencies have  it is something we have invested in deliberately.

Yes. We sign Non-Disclosure Agreements before any technical discussion begins. Protecting the confidentiality of your product idea, business model, and proprietary data is something we take seriously.

You do. Upon completion of the final payment, full intellectual property in the source code, design assets, and all project deliverables transfers to you. There are no licensing fees, ongoing royalties, or usage restrictions.

Security is built into our development process from the start. We follow the OWASP Mobile Security Testing Guide, implement encryption at rest and in transit, use OAuth 2.0 for authentication, apply certificate pinning where appropriate, and conduct security-focused QA before launch. For regulated applications, we arrange independent penetration testing. See our mobile app security guide.

Yes. Our app modernisation practice migrates legacy mobile applications to modern, maintainable architectures. This typically involves a technical audit, a phased migration plan, and careful management of the transition to avoid disrupting existing users.

Yes. Our maintenance and support service is available as a monthly retainer covering OS update compatibility, security patching, performance monitoring, bug fixes, and ongoing feature development. We recommend budgeting approximately 15–20% of your build cost annually for responsible post-launch maintenance.

Yes. We build native iOS apps (Swift), native Android apps (Kotlin), and cross-platform apps for both platforms (Flutter or React Native). The right approach depends on your timeline, budget, target audience, and technical requirements — which we assess during discovery.

An MVP (Minimum Viable Product) is the simplest version of your app that allows you to test your core value proposition with real users. Whether you need one depends on your situation. If you have significant uncertainty about user needs or product-market fit, an MVP is often the right starting point. If you have strong validated demand and adequate funding, it may be more efficient to build the fuller product. Our MVP development service includes a strategy consultation to help you make this decision correctly.

Yes. We provide ASO as part of our launch service — optimising app title, subtitle, description, keyword fields, screenshots, preview videos, and category selection for maximum organic visibility in the UK App Store and Google Play. For apps where organic store discovery is a significant growth channel, we can extend this into an ongoing ASO programme.

Yes frequently. Many of our UK clients are seed-to-Series B companies that need a development partner capable of moving at startup speed while maintaining the code quality standards that will withstand technical due diligence at later funding rounds. We understand the investor context and build accordingly.

Evaluate potential partners on: portfolio depth in your industry, seniority of the team that will actually work on your project, transparency about their process, references from completed projects, code quality standards (ask to see example code or a technical audit), and their approach to post-launch support. Our guide on how to choose an app development company covers the full evaluation framework.

Yes. We have built on-demand apps across multiple verticals — food delivery, fuel delivery, ride-hailing and home services — for the UK market. Two-sided marketplace dynamics, UK payment provider integration, and real-time matching infrastructure are all within our standard capabilities.

Yes. For use cases where a native app is not the right solution — limited budget, web-first audience, no need for device hardware access — a progressive web app can deliver an app-like experience at lower cost. We assess whether PWA is the right approach during discovery, rather than defaulting to native when it isn't warranted.

Yes. We integrate AI capabilities — including recommendation engines, NLP chatbots, image and voice recognition, predictive features, and generative AI  into mobile applications. Our AI consulting service helps UK businesses identify which AI features will genuinely benefit their users versus those that add technical complexity without proportionate user value.
