I will do ai mobile app development in react native expo app supabase for ios android

About this gig
Everyone wants AI in their app, but most AI apps are a chat box bolted onto a half-built product. Answers are slow, costs are unpredictable, and there is no login, so anyone can use your API key for free.
That is the real risk: an AI feature without a backend leaks money. Keys sit inside the app, usage is not limited, and one busy week can leave you with a bill you cannot cover.
A working AI mobile app keeps the AI call on a server, limits usage per user, and wraps it in a screen people want to open.
I build your AI app in React Native with Expo for iOS and Android, using OpenAI or Claude behind a secure backend (Supabase or Firebase). Ive shipped my own apps to both stores, so I build with review in mind.
What I build for you:
- AI chatbot, voice or image feature for your use case
- Secure backend: API keys stay off the phone
- Login and usage limits per user
- Subscription paywall and admin panel in Premium
- iOS and Android from one codebase
- A test build on your phone before delivery
- Full source code

Users won't trust an app that feels sluggish, looks generic, or doesn't clearly and visibly show them that their funds are actually protected.
And unlike most other app categories, fintech doesn't give you a second chance after a security scare one breach, one story of funds going missing, and your entire user base evaporates and never comes back, no matter how good the rest of the app was.
