Mobile Applications
Native Experiences, Cross-Platform Efficiency
Mobile app development London team shipping iOS, Android, React Native, and Flutter apps for UK businesses. Launchwork's last 5 React Native builds shipped to both stores in median 11 weeks discovery-to-launch versus a UK industry median of 18 weeks (Statista Q1 2026). On-device AI inference (Apple Intelligence + Gemini Nano) is now production-viable for SMEs — we shipped 2 apps in 2026 using local LLM features rather than cloud APIs, removing per-call cost and latency. Cross-platform React Native runs £15,000–£45,000 for typical business apps; separate native Swift + Kotlin runs 60–90% more for equivalent scope.
Mobile app development London teams build iOS and Android apps for UK businesses using React Native, Flutter, or native Swift and Kotlin. Launchwork Digital ships from £15,000 (MVP cross-platform) to £150,000+ (complex native with backend, payments, and AI features) in a median 11 weeks discovery-to-launch — faster than the UK 18-week median. Quotes inside 24 hours, App Store and Google Play submission included.

Frequently Asked Questions
Common questions about our mobile applications services.
How much does mobile app development cost in London?
Mobile app development in London splits predictably by complexity. A simple MVP (single platform, 5–10 screens, no backend) runs £15,000–£30,000. A typical UK business app with React Native cross-platform delivery, user accounts, payments, push notifications, and an admin panel runs £30,000–£60,000. Feature-rich apps with offline sync, real-time data, or third-party hardware integration run £60,000–£120,000. Native iOS plus native Android for the same scope costs 60–90% more than React Native. We publish a complete UK mobile app cost breakdown with line-item examples and quote fixed prices within 24 hours of the discovery call. Phased delivery (MVP first, features added each quarter) lets smaller budgets ship sooner.
How long does it take to build a mobile app in the UK?
An MVP cross-platform app launches in 8–12 weeks. A typical UK business app with payments, accounts, and admin tools takes 12–20 weeks. Complex apps with real-time features, AI, or hardware integration run 4–8 months. Our last 5 React Native builds shipped to both stores in median 11 weeks discovery-to-launch versus the UK industry median of 18 weeks (Statista Q1 2026). We work in 2-week sprints with a TestFlight or Firebase distribution build from week 3 so stakeholders test on real hardware throughout, not at the end. App Store and Google Play review adds 1–3 days for routine submissions, longer for first-time publishers without an established developer account.
React Native vs native iOS/Android — which should I choose?
React Native is the right choice for around 80% of UK business apps. You ship to iOS and Android from one codebase, saving 60–90% on engineering cost versus separate native builds, with performance indistinguishable from native for typical CRUD, payments, and content apps. Native (Swift or Kotlin) wins when the app is performance-critical (high-frame-rate games, AR, intensive video processing), when it must integrate deeply with platform-specific hardware (CarPlay, Apple Watch complications, Android Auto, advanced camera APIs), or when on-device AI inference using Core ML or Gemini Nano is a primary feature. Flutter is a credible third option, slightly slower than React Native for hiring and ecosystem, slightly stronger on visual consistency across platforms. We recommend cross-platform by default and only suggest native when the technical brief demands it.
Do you handle App Store and Google Play submission?
Yes, full App Store Connect and Google Play Console submission is included in every build at no extra cost. We set up your developer accounts if you don't have them yet (£79/year Apple, £20 one-off Google), prepare ASO-optimised metadata (app title, subtitle, keyword field, descriptions, screenshots in all required device sizes, preview video), handle the privacy nutrition label and data safety form, and manage the review process including responding to reviewer questions or policy queries. We also configure phased releases (staged rollout on Google Play, ProductPage A/B testing on App Store), prepare TestFlight beta builds for client UAT before public submission, and walk you through how to read the post-launch analytics dashboard. First-time publishers add 1–2 weeks for account verification.
What does post-launch app maintenance cost?
Mobile apps require ongoing maintenance even when no new features ship — iOS and Android both release SDK updates each autumn that frequently break older apps if dependencies aren't updated. Our maintenance plans start at £250/month for security patches, dependency updates, OS-compatibility regression testing, and crash analytics monitoring. The Growth tier (£500/month) adds a fixed monthly engineering allocation (4 hours) for small content or UI changes plus priority bug triage. Larger apps with real-time backends or payment flows typically need £1,000–£2,500/month covering server costs, payment provider compliance updates, and a larger engineering allocation. Apps left unmaintained for 12+ months are usually rejected by Apple at the next submission for failing to meet current SDK and privacy requirements.
