JOB OVERVIEW

OVERVIEW
We are building a performance system that removes decision-making from training and installs consistency.
This is not a typical fitness app.
This is a structured, behavior-driven system with future hardware integration (BLE).
We already have:
• UI/UX defined
• Developer specification
• System logic
You will execute the build.
—
SCOPE (Deliverables, not tasks)
You are responsible for delivering:
• Functional mobile app (React Native — cross-platform iOS + Android)
• Working onboarding ? session ? completion flow
• Dashboard (streak, session status)
• Simulation mode (mock data, no hardware required initially)
• Clean UI matching provided wireframe
—
PREFERRED STACK
• React Native (required)
• Firebase or Supabase backend
• REST API structure
—
TIMELINE
• Week 1: App shell + onboarding
• Week 2–3: Session flow + logic
• Week 4: Dashboard + polish
• Week 5–6: Iteration + fixes
—
COMMUNICATION REQUIREMENTS
• Daily progress updates
• Clear reporting of blockers
• Response time within 12 hours
—
PAYMENT STRUCTURE
• Milestone-based payments
• Paid per completed phase
• Final payment upon working V1 delivery
• Rate: $1,200–$1,700 USD for full V1 delivery
—
???? NON-NEGOTIABLE APPLICATION REQUIREMENTS
If any of the below are missing, the application will not be reviewed.
—
1. Start your application with:
SYSTEM BUILDER – AI BANDS
—
2. Answer this:
If the hardware device is not ready yet, how would you build and test the app?
—
3. Answer this:
What is the simplest version of this product you would build first?
—
4. Provide:
• 2–3 mobile apps you have built
• Your exact role in each
—
5. Confirm:
“I can deliver a clean MVP in 3–6 weeks and iterate quickly.”
—
6. Record a 1–2 minute video (required):
Explain how you would approach building this product from day one.
—
7. Final question:
Why do most fitness apps fail?
—
TECHNICAL EXPECTATIONS
• Clean, minimal UI (no overengineering)
• Structured, readable code
• Smooth performance on real devices
• No unnecessary features beyond scope
—
IMPORTANT
This is an execution role.
We are not looking for ideas — we are looking for delivery.
