About this service

Summary

Need a mobile app that actually thinks? I build React Native (iOS + Android) apps with real AI brains — powered by OpenAI’s GPT models and custom logic.
You’ll get:
Fully functional React Native app
GPT-powered assistant or chatbot
Voice and/or text interface
Custom backend (FastAPI or Node.js)
Optional Supabase login, data storage, task logic, etc.
Whether it’s a startup MVP, a productivity tool, or a niche AI assistant, I’ll make it real — fast.

Process

1. Free Consult Call We’ll chat about your idea, goals, and what kind of AI features you want built in.
2. Scope + Plan I’ll outline the core features, design direction, and confirm the tech stack (React Native + GPT + backend).
3. Build Phase I build your app in sprints, and keep you updated. You’ll get a working prototype ASAP and full source code on delivery.
4. Final Delivery + Support You get the finished mobile app, codebase, documentation, and 1 week of post-delivery support if anything breaks.

FAQs

  • What can the AI in the app do?

    Almost anything GPT can do — chat, plan, remind, interpret voice input, write text, interact with customers, schedule meetings and more. I’ll help tailor it to your needs.

  • Do I need to provide designs or wireframes?

    Nope! I can design the whole thing or work from a rough sketch or idea.

  • Can this work offline or without an OpenAI API key?

    Not yet — it requires a GPT key for live AI responses, but I can help set that up for you.

  • Can you publish the app to the App Store or Google Play?

    Yes — I can help with deployment, or guide you through the process depending on your budget.

  • Do you build apps for X industry?

    Yes! I build apps for any and all types of industries, businesses, nonprofits, etc.
