Comprehensive Fitness & Nutrition Tracking Platform
Fitness professionals and their clients needed a unified platform to manage workout programs, track nutrition intake, monitor progress, and communicate - replacing fragmented spreadsheets and messaging apps.
Discuss Your ProjectThe Challenge
Fitness management was spread across disconnected tools:
- Workout programs were shared via PDFs or spreadsheets with no tracking
- Nutrition logging required separate apps with no trainer visibility
- Progress photos, measurements, and performance data lived in different places
- Communication between trainer and client happened in messaging apps without context
- No role-based system differentiating trainer, trainee, and admin capabilities
Our Solution
We built a comprehensive fitness management platform with role-based dashboards, a 2400+ food database, exercise libraries, and progress analytics.
Architecture
- Backend: NestJS with PostgreSQL, TypeORM, Redis, Bull job queue
- Trainee Web App: React with Redux Toolkit for client-facing features
- Trainer Web App: React with Redux Toolkit for professional tools
- Admin Dashboard: React with Ant Design for platform management
- Mobile App: React Native/Expo with Zustand and i18n support
- Media: AWS S3 for storage, AWS Transcribe for audio processing

Frequently Asked Questions
MicrocosmWorks integrated a food recognition AI that identifies dishes from photos and estimates portion sizes, combined with a nutritional database containing over 800,000 food items including restaurant meals and packaged products. The system allows users to confirm or adjust the AI's estimates and learns from corrections to improve accuracy over time, achieving approximately 85-90% accuracy on common foods which is comparable to manual entry but takes a fraction of the time.
Yes, MicrocosmWorks built data connectors for Apple Health, Google Fit, Strava, Garmin Connect, Fitbit, and MyFitnessPal, aggregating workout sessions, daily activity metrics, and body composition data into a unified timeline. The platform handles deduplication when the same workout is recorded by multiple sources and normalizes metrics across different device ecosystems so users see consistent data regardless of which combination of apps and wearables they use.
MicrocosmWorks developed a nutrition planning engine that calculates personalized macro targets based on the user's basal metabolic rate, activity level, body composition goals, and training schedule, then generates meal suggestions that meet those targets while respecting declared dietary restrictions like vegan, keto, gluten-free, or religious dietary laws. The system adjusts targets dynamically based on actual workout intensity logged each day, increasing carbohydrate allocation on heavy training days and reducing it on rest days.
MicrocosmWorks built a progressive overload tracking engine that analyzes workout logs to detect when a user has consistently performed at or above their target reps and sets for a given exercise across multiple sessions. The system then suggests specific weight increases, rep range adjustments, or exercise progressions based on established strength training principles, and tracks the user's response to the increase to determine if the progression was appropriate.
MicrocosmWorks builds fitness and nutrition tracking platforms at rates of $20-$40/hr, with an MVP including food logging, workout tracking, wearable integration, and basic nutrition planning typically delivered in 3-4 months. This is significantly more cost-effective than white-labeling existing platforms like Trainerize or TrueCoach, which charge per-user fees that erode margins as your user base grows, and a custom build gives you complete control over the user experience and data.
