MLA Fitness App

A simple and interactive fitness tracking application built with multiple microservices and programming languages. This application allows users to track their exercises and monitor their progress over time.

The Activity Tracking functionality uses the MERN stack (MongoDB, Express.js, React, Node.js), the Analytics service uses Python/Flask and the Authentication Microservice using Java.

Current Features

• User registration for personalized tracking
• Log various types of exercises with descriptions, duration, distance, date and get real time pace and speed
• See overall statistics like with new chart
• weekly statistics with weekly target
• User profile with information like height, weight and BMI
• Real-time data persistence with MongoDB

Prerequisites

• Node.js
• MongoDB
• npm or yarn
• Python Flask
• Java 8 (all already installed in the devcontainer)
