Fitness Tracker

This fitness tracking application helps users monitor their workouts, track progress, and follow personalized training plans. The app includes features for creating custom workouts, logging exercises, and analyzing performance over time.

Key features include:

• Workout plan creation and customization
• Exercise logging with sets, reps, and weights
• Progress tracking with charts and statistics
• Body measurements and weight tracking
• Calorie counting and nutritional information
• Achievement system for motivation
• Community challenges and social sharing
• Integration with fitness wearables

The application was developed using React Native for cross-platform mobile compatibility. The backend was built with Node.js and Express, with MongoDB for data storage. GraphQL was used for efficient API queries.

One of the main challenges was designing an intuitive interface for logging workouts quickly during exercise sessions. This was addressed through extensive user testing and iterative design improvements.
