# I Will Build Your AI Mobile App for iOS and Android with Flutter

Your AI mobile app idea deserves a skilled team that can take it from concept to a polished, store-ready product — and that is exactly what [Zinn Digital](https://zinnhub.com/zinns/flutter-app-development-for-android-and-ios-with-firebase-by-zinn-digital/) delivers.

We are a London-based Flutter development studio specialising in cross-platform AI mobile applications. Using a single, unified Flutter codebase, we build apps that run beautifully on both iOS and Android, saving you time, budget, and the headache of maintaining two separate projects. Every app we deliver is built with clean architecture, secure authentication, and real AI integration — not superficial features bolted on as an afterthought.

\*\*What is included in every tier:\*\*

— A fully functional iOS app
 — A fully functional Android app
 — Integration of an AI model into your app (including support for OpenAI GPT and similar)
 — Secure user authentication
 — Complete source code delivered to you

Our technology stack covers the full product lifecycle. On the frontend, we work in Dart and Flutter. Our backend expertise spans Node.js, Express.js, and Python. For databases, we use PostgreSQL, MongoDB, and Firebase depending on your needs. AI capabilities are powered by frameworks including OpenAI GPT, and we can connect to third-party APIs or build tailored AI logic from scratch.

\*\*Who is this for?\*\*

This service is ideal for founders, product teams, and businesses who want to launch an [AI-powered mobile](https://zinnhub.com/zinns/create-ai-mobile-apps-android-ios-flutter-development-by-zinn-digital/) product without building an in-house development team. Whether you have a detailed specification or a rough idea you need help refining, we will guide you through every step.

\*\*How it works:\*\*

1. Place your order and share your project brief.
 2. We review your requirements and reach out via order chat if we need further details.
 3. Development begins with regular progress updates.
 4. You review, request revisions, and approve the final build.
 5. We deliver the complete source code and support your app store deployment.

For projects requiring a full custom UI/UX design, chatbot integration, or AI model fine-tuning, our Standard and Complete tiers cover these in full — see the packages below for a clear breakdown of scope.

\*\*Why Zinn Digital?\*\*

We are cross-platform specialists focused exclusively on Flutter. Our AI integration experience means we understand not just the code but the product logic that makes AI features genuinely useful. We are based in London, offer unlimited revisions across all tiers, and provide 24/7 support throughout your project. We do not disappear after delivery — post-launch guidance, minor updates, and troubleshooting are part of how we work.
