    Frequently Asked Questions

    Below are some of the common questions which may help you in your journey.

    Mobile app development costs in the UK range from ÂŁ10,000 to ÂŁ300,000. A basic app costs ÂŁ10,000-ÂŁ40,000, a moderately complex app costs ÂŁ40,000-ÂŁ100,000, and a feature-rich enterprise app costs ÂŁ100,000-ÂŁ300,000+.

    Building a mobile app takes 3-9 months on average. Simple apps require 2-4 months, medium complexity apps take 4-6 months, and complex enterprise applications need 6-12+ months from initial concept to App Store launch.

    Choose native app development (Swift for iOS, Kotlin for Android) for maximum performance, complex features, and best user experience. Choose cross-platform development (Flutter, React Native) to save 30-40% on costs and reduce time-to-market while maintaining good performance for most business apps.

    Mobile app development in the UK includes business analysis, UI/UX design, iOS and Android development, backend development, API integration, quality assurance testing, App Store submission, deployment, and ongoing maintenance support.

    iOS app development in the UK costs between ÂŁ15,000 and ÂŁ250,000. A simple iOS app costs ÂŁ15,000-ÂŁ45,000, a medium complexity app costs ÂŁ45,000-ÂŁ120,000, and a complex enterprise iOS app costs ÂŁ120,000-ÂŁ250,000+.

    You need both iOS and Android apps if you want to reach the maximum UK audience (iOS holds 51% market share, Android 48%). Start with both platforms if budget allows, or prioritize based on your target demographic—iOS for affluent users aged 25-45, Android for broader demographics and global reach.

    The mobile app development process consists of 6 key phases: Discovery & Planning (2-4 weeks), UI/UX Design (3-6 weeks), Development (8-20 weeks), Quality Assurance Testing (2-4 weeks), App Store Deployment (1-2 weeks), and ongoing Maintenance & Support.

    Yes, we specialize in MVP mobile app development for startups. An MVP app in the UK costs ÂŁ15,000-ÂŁ50,000 and takes 2-4 months to build, focusing on core features needed to validate your business idea and gather user feedback before full-scale development.

    We can add 100+ features to mobile apps including user authentication, push notifications, payment processing, GPS/maps, camera integration, social media login, in-app chat, offline mode, barcode scanning, video streaming, AR features, AI/ML capabilities, wearable integration, and custom API integrations.
