The 5 questions our editors get most often, answered honestly. These apply to mobile app development as a discipline regardless of city. Curated by humans ### How much does it cost to build a mobile app with a UK agency in 2026? UK mobile app pricing splits by complexity and team type. A lean MVP from a boutique studio runs £15,000-40,000, mid-market agencies £30,000-70,000, and enterprise dev houses £60,000-120,000 and up. Full production apps with payments, custom backends, and proper QA sit at £40,000-180,000 across the mid-market, climbing past £400,000 for regulated or enterprise work. Capacitor and hybrid builds are cheapest at £10,000-80,000. Maintenance retainers typically run 15-20% of the build cost per year. ### How long does mobile app development take from kick-off to App Store launch? UK practitioner consensus is consistent. A simple MVP runs 8-12 weeks, a standard business app 16-30 weeks, and a complex enterprise or fintech build 6-12 months. The phases are roughly: discovery 1-3 weeks, design 2-6 weeks, build 4-16 weeks or more, QA on a real-device matrix 1-4 weeks, and store submission 1-3 weeks. Apple review typically lands in 1-3 days and Google in 1-7 days once the binary is submitted, assuming privacy disclosures and metadata are clean. ### Should I build native iOS and Android or use cross-platform React Native or Flutter? Native (Swift, Kotlin) wins on platform-specific UX polish, deep OS integrations, and access to new features the moment Apple or Google ships them. React Native and Flutter have closed most of the gap for standard product work, run one codebase across both platforms, and usually cost 30-50% less than building twice natively. Most new UK briefs in 2026 land on cross-platform unless there is a specific reason not to. ### What is included in mobile app development versus what gets billed separately? A proper scope covers discovery, UX and UI design, engineering, backend or API work, QA across a real-device matrix, App Store and Google Play submission, and a defined warranty window for bug fixes. Things often billed separately or skipped by cheaper quotes: maintenance retainers, App Store Optimisation, analytics set-up, fixes for older OS versions, and compliance work (App Tracking Transparency consent, Data Safety forms, GDPR). Ask for line items, not a single project number. ### What are the main red flags when hiring a mobile app development agency? Refusal to name the actual delivery team or disclose offshoring. QA only on simulators with no real-device matrix. Treating launch as just uploading a binary, with no App Store Optimisation or plan for review rejections. No SLA on post-launch bug fixes and no warranty period in the contract. Proprietary backends that lock the brand in and make migration painful. Inability to discuss App Tracking Transparency, Google Play Data Safety, or EU DMA distribution rules.
