That is exactly what this service delivers: a fully functional, AI-integrated iOS and Android application built with Flutter or [React Native](https://zinnhub.com/zinns/develop-your-ios-and-android-mobile-app-using-expo-and-react-native/), complete with source code and ready for real-world deployment. Zinn Digital is a London-based development team with over five years of hands-on experience building AI-powered mobile applications, chatbot integrations, and SaaS solutions. Every project is handled with care, clear communication, and a focus on shipping something that genuinely works. WHAT IS INCLUDED ACROSS ALL TIERS Every package includes a fully functional iOS and Android application built with Flutter or React Native, integration of an AI model into your app, complete source code delivery, and unlimited revisions. You will also receive regular progress updates throughout the build, and the team remains accessible via order chat at every stage. HOW IT WORKS 1. You share your project brief, feature requirements, and any design assets or inspiration. 2. The team reviews your requirements and confirms scope before development begins. 3. Development proceeds with regular milestone check-ins so you are never in the dark. 4. You review the build, request revisions, and sign off on the final deliverable. 5. Source code is handed over clean and ready to deploy. WHAT THE TIERS COVER The Starter tier is ideal for a straightforward MVP or proof-of-concept: a 3–5 screen cross-platform app built to your provided UX/UI design, with AI model integration and full source code — a focused scope that keeps delivery realistic and quality high. The Standard tier adds AI model fine-tuning and a fully integrated chatbot, giving your app a more intelligent, conversational layer. This tier suits businesses that want a polished, interactive product beyond a basic MVP. The Full Build tier is the complete package: fine-tuned AI model, [chatbot integration](https://zinnhub.com/zinns/ai-website-development-with-chatbot-agent-custom-business-sites/), user authentication, and an extended timeline to accommodate greater complexity and thorough testing — the right choice for a production-ready application. WHO THIS IS FOR This service suits founders validating an app idea, businesses adding AI functionality to an existing product, and teams who need a reliable development partner without the overhead of a full in-house build. TECH STACK Frameworks: Flutter, React Native. Backend: Node.js, Express.js, Laravel, Python. Databases: MySQL, MongoDB. Cloud and hosting: AWS, DigitalOcean. If you are ready to bring your app idea to life with genuine AI capability baked in, this is the team to do it.
