User Flow Analysis: Roles & Capabilities
This section details the distinct feature sets and user journeys for the three defined roles: the self-starting **Free User**, the professionally coached **Premium User**, and the business-focused **Trainer**. Click the tabs to explore each flow.
Free User: The Self-Starter
Purpose: Free users can track their food consumption and workouts manually, or create simple, repetitive meal and workout templates. This tier serves as the primary funnel for the platform.
Meal Tracking Flow (Manual)
- •Select 'Track Meal' > 'Add meal for the day'
- •Enter food name (e.g., Spaghetti Bolognese)
- •Enter food type (e.g., carbs, protein)
- •Enter food quantity and calorie amount (Manual calculation required)
- •Save, updating the daily calorie total.
Key Capabilities
- •Basic manual entry for meals and workouts.
- •Create simple reusable meal templates (e.g., "Daily Coffee").
- •Basic progress overview and daily summary (Calories In vs. Out).

Business Model & Monetization Strategy
The FYTHUB model is built on shared success. The visualizations below detail the revenue structure and the value of the Trainer Marketplace.
Trainer Revenue Share
Percentage of subscription revenue retained by the Trainer vs. FYTHUB.
The Trainer Marketplace
The Marketplace allows trainers to publish "plan packages" (e.g., 8-week Strength and Nutrition programs) that any FYTHUB user can subscribe to, generating a passive income stream for the trainer.
- •Passive Income: Plans sold to users not in a direct coaching program.
- •Quality Control: Admins approve all public plans before listing.
- •Scalability: Allows trainers to monetize content globally, expanding reach beyond 1:1 sessions.
Technical Strategy: Backend Decision
A critical decision was made to prioritize Supabase (PostgreSQL) over Firebase (NoSQL) to ensure long-term cost predictability, handle complex trainer-client relationships, and support robust search capabilities.
Key Architectural Advantage
Comparison of critical factors for the FYTHUB business model.
Why Supabase (SQL) is Superior
- •Cost Predictability: Supabase offers fixed tiers, mitigating the "Pay-per-Read" volatility of Firebase. This is crucial given the high-volume logging by free users.
- •Relational Data: The Trainer (1) to Client (Many) to Log (Many) structure is natively handled by SQL, avoiding complex, costly, and error-prone NoSQL duplication.
- •Native Search: PostgreSQL has superior built-in Full Text Search, eliminating the need for expensive third-party search tools (like Algolia) for the meal/exercise database lookup.
- •Less Lock-in: Based on open-source PostgreSQL, providing future flexibility for migration or hybrid solutions.
