# I Will Build a Custom Flutter Mobile App with AI Chatbot Integration

You have an app idea. What you need now is a development team that can turn it into a real, working product on both Android and iOS — without the back-and-forth, the missed deadlines, or the mystery of what is actually being built.

Zinn Digital is a London-based Flutter and [React Native](https://zinnhub.com/zinns/develop-ios-and-android-apps-using-react-native-with-firebase/) development team specialising in AI-driven mobile applications. We combine technical depth with a genuine eye for design, delivering apps that perform well, look great, and are built to grow with your business.

Every project starts with understanding your goals. Whether you are launching a brand-new app, adding AI capabilities to an existing product, or need a clean, authenticated interface built quickly — we match the scope to what you actually need.

\*\*What you get across all packages:\*\*
 – A Flutter or [React Native](https://zinnhub.com/zinns/be-your-react-native-firebase-and-flutterflow-mobile-app-developer/) app built to your UI design and requirements
 – Authentication flow (login, signup) built in from the start
 – Integration of an AI model into your app
 – Full source code delivered — no lock-in, no hidden extras
 – Application and interface design included
 – Unlimited revisions until you are satisfied

\*\*The Starter package\*\* covers a focused 3–5 screen app with AI model integration, authentication, and complete source code — ideal for MVPs, prototypes, or a core feature build.

\*\*The Standard package\*\* scales up to a fully functional Android and iOS app, adds chatbot integration, and gives you more development runway with a 14-day delivery window.

\*\*The Full Build package\*\* includes everything in Standard plus AI model fine-tuning, meaning the AI is not just plugged in — it is trained and optimised to suit your specific use case. This is the package for production-ready apps that need to perform at a high level from day one.

\*\*Our technology stack:\*\*
 Frontend: Flutter, React Native, React.js, Next.js
 Backend: Node.js, PHP, Laravel, Express.js, Python
 Database: MongoDB, MySQL
 Tools: VS Code, Android Studio, Xcode, Figma, GitHub

\*\*Who this is for:\*\*
 Startups validating an idea, businesses adding mobile to their offering, product teams needing AI features built properly, and founders who want a reliable team with clear communication and regular progress updates — not silence followed by a surprise delivery.

We keep you informed throughout, flag decisions early, and do not close an order until you are genuinely happy with what has been built.
