Mobile App Development agencies.

Mobile App Development is the build of iOS and Android applications, native (Swift or Kotlin) or cross-platform (React Native, Flutter, or Capacitor), covering discovery, UX and UI design, engineering, QA on real devices, App Store and Google Play submission, and post-launch maintenance. It sits next to web development but answers to a different set of platform rules.

Editor's note
Mobile App Development in the UK splits, in 2026, into three honest tiers. Boutique studios ship MVPs in the £15,000-40,000 band. Mid-market agencies running production apps with custom backends, payments, and proper QA sit at £30,000-180,000. Enterprise dev houses handle regulated multi-team builds from £150,000 into six figures. AgencyIndex tags 115 UK agencies as Mobile App Development providers. The stack shapes the bill. Native iOS or Android wins on platform polish and deep OS integrations. React Native and Flutter have closed most of the gap for standard product work and run one codebase across both platforms, which is why most new UK briefs land there. Capacitor and hybrid builds are cheapest but expensive to retrofit later. Three shifts now sit underneath every brief. The EU Digital Markets Act has opened sideloading on iOS in Europe. App Tracking Transparency and Google Play's Data Safety form have made privacy disclosures a release-blocking item, not a launch-week afterthought. And AI-assisted development is compressing the cost of boilerplate without touching the cost of discovery, architecture, QA, or store submission. Filter the index by platform, stack, sector, and ownership to find who is actually doing the work.
Typical cost
