FAQ
Frequently Asked Questions
How much does mobile app development cost in the UK?
SAM AI Solutions app development costs depend on complexity and platform. A simple MVP app (5–8 screens, basic functionality) starts at £25,000–£45,000. A mid-complexity app with user authentication, API integrations, push notifications, and payment processing typically costs £50,000–£120,000. A full-featured consumer app or enterprise platform ranges from £120,000–£300,000+. We provide a fixed-price quote after a free discovery workshop.
How long does mobile app development take?
SAM AI Solutions delivers a working app MVP in 10–14 weeks using our agile sprint process. A full-featured consumer app typically takes 16–24 weeks. Enterprise apps with complex backend systems, multiple user roles, and third-party integrations take 24–40 weeks. You see working screens every 2 weeks, not just a final build at the end.
Should I build a native app or cross-platform app?
Cross-platform development (React Native or Flutter) is the right choice for most UK businesses, it delivers native-quality performance for both iOS and Android from a single codebase at 60–70% of the cost of two native builds. SAM AI Solutions recommends native Swift (iOS) or Kotlin (Android) only when the app requires intensive graphics, hardware-specific integrations, or real-time video processing that demands maximum performance.
Which companies provide mobile app development in the UK?
The UK app development market includes global agencies (Accenture, IBM iX, Deloitte Digital), mid-size specialists, and boutique studios. SAM AI Solutions operates from London and competes on the combination of senior talent, proven process (80+ apps delivered, 4.8★ average App Store rating), and transparent fixed pricing, without the overhead rates of big-four consultancies.
Do you handle App Store and Google Play submission?
Yes. SAM AI Solutions manages the entire submission process: provisioning profiles, code signing, TestFlight/internal testing, App Store and Play Store listing optimisation (ASO, screenshots, descriptions, keywords), privacy manifests, and the review process. Our apps have an excellent first-submission approval rate. We handle any rejection responses on your behalf.
Can you take over an app that was started by another developer?
Yes. SAM AI Solutions regularly inherits part-built or poorly-built apps. We start with a thorough code audit assessing architecture quality, security vulnerabilities, technical debt, and maintainability. We then provide a clear recommendation, fix and continue, or rebuild on a more solid foundation, with honest cost and risk analysis for both options.
