Flutter Developer — Mobile App (AI-assisted health project)
Budget: $250 – $750 USD
I’m building a mobile app connected to a smart body-fat scale.
The app includes:
A basic scale app (measurements, history, trends)
An optional 30-day challenge unlocked via an activation code
An AI-based diet coach
Very light human coach touchpoints (already defined)
The product logic, flows, and features are already designed and documented.
I’m looking for a developer to implement, not reinvent, the product.
What you’ll work on
Inside an existing Flutter app, you’ll help implement or finalize:
AI chat interface (simple chat UI + backend connection)
Challenge activation flow (manual code entry)
Challenge state logic (day counter, start/end)
Integration with Firebase (Auth + Firestore)
A simple human coach chat screen (WebView / embedded chat)
The backend is lightweight (Firebase + simple API).
No complex admin panel, no heavy analytics, no advanced ML work.
What you don’t need to do
No product design
No AI model training
No complex dashboards
No marketing funnels
No feature ideation
Everything is already scoped and documented.
Tech stack (current)
Flutter
Firebase Auth
Firestore
Simple Node.js / serverless backend for AI calls
OpenAI API (already abstracted)
Who this is for
This is a good fit if you:
Have experience with Flutter apps
Are comfortable working with Firebase
Have built chat-like features before (or similar)
Can follow written specs and ask questions when needed
Prefer clear scope and execution over constant changes
You do not need to be an AI expert — guidance and documentation are provided.
How the process works
Short chat to check fit
If shortlisted, you receive the full internal docs (product + tech)
We agree on milestones and timeline
You build, test, and deliver
