What You'll Receive
Full Description
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 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 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.

Frequently Asked Questions
To get started we need your app idea and goals, your target audience, the key features you want, any design assets or UI references you have (Figma files, screenshots, brand guidelines), and any backend credentials or API keys if we are integrating into an existing system. The more detail you provide, the faster we can move.
Flutter and React Native allow us to build one codebase that runs on both Android and iOS. This significantly reduces development time and cost while still delivering high performance and a consistent user experience across both platforms. For most commercial app projects, it is the most practical and cost-effective approach.
We can integrate a range of AI capabilities including AI chatbots, natural language processing, voice recognition, image processing, machine learning models, and recommendation systems. The Full Build package also includes fine-tuning of the AI model to suit your specific data and use case.
It means we will keep refining the delivered work until it meets your requirements as agreed at the start of the project. Revisions cover adjustments within the original agreed scope — significant changes to features or screens beyond what was specified may require a scope discussion.
Yes, full source code is included in every package. You will own the code outright and can take it to any developer or host it however you choose after delivery.
Yes. Custom and third-party API integration is part of our capability, including social media integrations. If you have a specific API or platform in mind, mention it in your requirements when you place the order.
We provide regular updates throughout the project via the order chat. You will not be left waiting and wondering — we flag any decisions or blockers early so nothing slows down delivery.
Yes, deployment on the Play Store and Apple App Store is something we offer. If you need assistance with submission and deployment, add the deployment addon at checkout or raise it in the order chat.
Customer Reviews
See what our customers say about this Zinn
Great experience overall. The developer took my rough idea and built a clean, fully functional AI mobile app out of it. Communication was smooth the whole time, and the delivery was right on schedule. The AI performance is actually impressive it’s responsive and accurate.
After seeing how well my last app performed, I didn’t think it could get better but this developer proved me wrong! The new AI-powered app is seamless, creative, and packed with intelligent functionality. It’s a pleasure collaborating with such a consistent professional.
Hiring this developer again was the right choice. My AI study assistant app not only functions perfectly but also offers insightful suggestions that actually help users. The development process was smooth, communication was excellent, and the final app exceeded my expectations.
It's rare to find a developer who consistently delivers top-notch work, but this one does! From design to AI functionality, everything was executed perfectly. Working with them again reaffirmed why I trust them completely for AI app development.
After the fantastic results from our first project, I went back to them for an AI-based wellness app and wow, he delivered again. The AI insights are spot-on, and the interface is beautiful. It feels like they just get what I need without over-explaining anything.
