iOS & Android App Development

A great mobile app keeps your brand in your customers' pockets. Crown IT Experts designs and engineers native and cross-platform apps for iOS and Android — from customer-facing consumer apps to internal tools that streamline your operations. We handle the full journey: strategy, UX, development, App Store submission and ongoing iteration.

We build with Swift, Kotlin, React Native and Flutter, choosing the right stack for your budget and roadmap rather than forcing a one-size-fits-all approach. Every app is backed by robust APIs, analytics instrumentation and automated testing, so you launch with confidence and learn from real user behaviour after release.

Frequently Asked Questions

• 01. Should I build a native or cross-platform app?
  It depends on your goals. Cross-platform (React Native / Flutter) is faster and more cost-effective for most business apps, while native development suits apps needing maximum performance or deep hardware integration. We advise honestly on the best fit during discovery.
• 02. How much does a mobile app cost?
  A focused MVP typically starts from around £15,000, with larger products scaling from there. After a free scoping call we provide a fixed, itemised quote so there are no surprises.
• 03. Do you maintain apps after launch?
  Yes. We offer ongoing support plans covering OS updates, security patches, performance monitoring and new feature development, so your app keeps improving after day one.
