Is there a food database for nutrition logging?

Yes. The nutrition module integrates with a food database API (USDA, Open Food Facts, or Nutritionix). Users search for foods, scan barcodes, or use saved custom meals. Macros are calculated automatically.

How does the coach-client portal work?

Coaches have an admin view where they create workout and nutrition plans and assign them to clients. Clients see their assigned plan in the app. Coaches can view client activity, progress metrics, and message them directly.

Can I sync data from wearables?

Yes. The app reads activity data from Apple HealthKit and Google Fit APIs, including steps, active calories, and heart rate. Synced data is merged into the user's activity timeline.

The Challenge

Why building a Fitness App from scratch is hard

Building a Fitness & Workout Tracking App from scratch requires months of development time and significant engineering resources. Teams struggle to coordinate frontend, backend, database, and authentication while managing fitness app-specific business logic, integrations, and role-based access rules.

What's Included

Everything your Fitness App needs

ProjectCode generates a production-ready Fitness App with all the modules your team needs from day one.

Workout plan builder with exercise library (video + instructions)

Workout logging with sets, reps, weight, and RPE

Progress tracking: body weight, measurements, 1RM PRs

Nutrition logging with macro targets and meal diary

Wearable sync: Apple Health, Google Fit

Coach-client portal for online personal training

Community features: workout sharing and challenges

AI-generated progressive overload suggestions

Architecture

How it's built

The generated Fitness App follows production-grade architecture patterns.

React 18 + TypeScript frontend with role-based dashboards tailored for fitness app workflows

NestJS REST API with dedicated fitness app modules, DTOs, validators, and service layer

PostgreSQL relational schema with normalized tables for all fitness app entities

JWT + Google OAuth authentication with granular permission gates per role

Real-time Socket.IO events for live fitness app status updates and notifications

Managed hosting with one-click deploy, custom domain, and auto-SSL

Database

PostgreSQL schema designed for Fitness App

ProjectCode generates a normalized, indexed PostgreSQL schema with the right tables and relationships for your use case. You own the schema and can evolve it freely.

workouts (id, user_id, plan_id, name, date, duration_minutes, exercises jsonb, notes, perceived_exertion, mood)
exercises (id, name, category, muscle_groups jsonb, equipment, demo_video_url, instructions)
body_metrics (id, user_id, date, weight, body_fat_pct, measurements jsonb)
nutrition_logs (id, user_id, date, meals jsonb, total_calories, protein_g, carbs_g, fat_g)

FAQ

Common questions about building a Fitness App

The app compares each workout set against the same exercise's previous session. It highlights new PRs and, based on the configured progression model (linear, double, RPE-based), suggests the next weight or reps.
