What You'll Receive
Full Description
Your business deserves an app that does more than display information — it should think, respond, and adapt. Whether you need a GPT-powered assistant, an AI chatbot embedded in a mobile experience, machine learning recommendations, or a fully integrated AI website alongside your app, this service delivers intelligent, scalable solutions built to perform from day one.
Zinn Digital™ is a London-based AI development studio with 5+ years of experience turning ambitious app ideas into production-ready cross-platform products. Every project is handled end-to-end: from UI/UX design and rapid prototyping through to frontend and backend development, AI model integration, and full source code delivery.
**What is included across all tiers:**
— Cross-platform app (functional iOS and Android builds)
— AI model integration into your app or existing product
— Application and website design
— Full source code included
— Unlimited revisions
— 60 days of post-launch support including bug fixes and updates
**The three tiers are structured around scope:**
The Essential tier covers a clean, focused 3–4 screen AI-powered app with core features — ideal for MVPs, proof-of-concept builds, or simple utility apps. The Standard tier adds chatbot integration for conversational AI within your app, expanding the screen count and complexity accordingly. The Full Build tier includes everything in Standard plus AI model fine-tuning and user authentication — the complete package for a production-grade AI application.
**Technology stack used:**
Frontend: React Native, Flutter, React.js, Next.js
Backend: Node.js, Express.js, Python
AI & ML: OpenAI GPT, TensorFlow, PyTorch
Database: PostgreSQL, MongoDB, Firebase
**AI features that can be integrated include:** chatbots, voice assistants, recommendation engines, image recognition, predictive analytics, sentiment analysis, natural language processing (NLP), and more — depending on your project scope.
If you already have a dataset or pre-trained model, it can be used directly. If not, the team will guide you through sourcing data or building and training models appropriate to your app's goals.
Data privacy and security are taken seriously: encryption, secure coding practices, and confidentiality measures are applied throughout every project.
**This service is right for you if** you are a founder validating an AI product idea, a business looking to add intelligent features to an existing app, or a team that needs a trusted development partner to handle the full build cycle — design, development, AI integration, and launch.

Frequently Asked Questions
To kick things off, it helps to share your app idea, target audience, desired features, design preferences, and business goals. The more context you provide, the faster the project can begin. A detailed requirements form is sent immediately after purchase.
Absolutely. The team can assess your current application and recommend the most suitable AI technologies to integrate — whether that is a chatbot, voice recognition, NLP features, or machine learning enhancements — without requiring a full rebuild.
Not necessarily. If you already have a dataset or model, it can be used directly. If not, the team will guide you through sourcing appropriate data or will build and train models as part of the agreed scope.
Yes. Development uses React Native or Flutter for seamless cross-platform performance across both iOS and Android. Native builds are also available upon request.
Every project includes 60 days of post-launch support covering bug fixes, app updates, and minor AI feature adjustments. Should you need further enhancements after that period, the team remains available to assist.
Data encryption, secure coding practices, and confidentiality measures are applied throughout the development process to protect your business data and your end users.
The delivery timelines shown in each package are the standard estimates. After you place your order and share your project details, a more precise timeline will be confirmed based on the complexity and scope of your requirements.
Essential suits MVPs and simple utility apps with AI features across 3–4 screens. Standard is the right choice when you need conversational chatbot capability built in. Full Build is the option for a complete production application that requires a fine-tuned AI model and user authentication.
