Project Overview:

The Fitness API Aggregator is a web-based and mobile-friendly platform that integrates multiple third-party fitness and health APIs (such as Fitbit, Google Fit, Apple Health, Strava, etc.) to provide users with a centralized dashboard for all their fitness metrics. It allows users to track and compare their health data (steps, heart rate, sleep, calories, workouts, etc.) from various sources in one place with meaningful insights and visualizations.

Technologies Used:

• Frontend: HTML, CSS, Bootstrap, JavaScript

• Backend: Node.js / PHP / Java

• Database: MongoDB / MySQL (for storing user data and logs)

• APIs: Google Fit API, Fitbit API, Apple HealthKit API, Strava API, etc.

• Visualization: Chart.js or D3.js

• Authentication: OAuth 2.0 (for secure API integration)
