Full Description
Your business deserves smarter tools. Whether you need an AI-powered mobile app that personalises user experiences, a chatbot that handles customer queries around the clock, or deep AI model integration into an existing product, this service delivers a production-ready, cross-platform solution built on proven, modern technology.
Zinn Digital is a professional AI development studio based in London, England. The team combines expertise in mobile engineering, machine learning, and large language models to build applications that do more than look good — they think, adapt, and work for your business continuously.
Every order is built on a robust, scalable stack: Flutter or React Native on the frontend for seamless iOS and Android deployment; Node.js, Express.js, or Python on the backend for reliable API performance; TensorFlow, PyTorch, and the OpenAI API for genuine AI capability; and Firebase, AWS (SageMaker, Lambda), or Google Cloud AI for cloud hosting and inference. Databases are chosen to suit your use case — MongoDB, PostgreSQL, or MySQL.
What you receive on every tier:
— A functional iOS and Android app built to your requirements
— Integration of an AI model (new or existing)
— AI model fine-tuning for your specific domain or data
— Application and UI/UX design
— Chatbot integration
— User authentication
— Complete, comprehensively commented source code
— Free pre-project consultation
— 24/7 availability throughout the build
— Post-launch support for bug fixes and improvements
The three packages are designed as natural stepping stones: the Starter tier is ideal for MVPs and proofs of concept with 3–4 screens; the Growth tier expands scope significantly for businesses that need a more complete product; and the Enterprise tier covers full-scale, production-grade AI applications with the longest runway for complexity and refinement.
This service is right for you if you are a startup founder validating an AI-first idea, an established business adding intelligent automation to an existing platform, or a product team that needs a reliable technical partner to take a concept from design to deployment.
All code is yours. All source files are delivered. No black boxes.
Reach out via the order chat before placing your order if you have questions — the team is available and happy to scope your project before you commit.
