Health Tracking Mobile App

Project Overview

Developed a cross-platform mobile application that helps users track various health metrics like steps, water intake, sleep, and nutrition. The app provides personalized insights and recommendations based on user data and goals.

Key Features

• Daily health metric tracking with visual progress indicators
• Personalized goal setting and achievement tracking
• Data visualization with interactive charts
• Smart notifications and reminders
• Social sharing and challenges with friends
• Integration with popular wearable devices

Technologies Used

• React Native for cross-platform development
• Firebase for authentication and real-time database
• Node.js and Express for the backend API
• TensorFlow.js for personalized recommendation algorithms

My Role

As the lead developer on this project, I was responsible for architecture design, frontend implementation, and integration with the backend services. I also implemented the machine learning components for generating personalized insights.

Process

The development followed an agile methodology with two-week sprints. We conducted extensive user research before development began and continued to gather feedback throughout the process. This user-centered approach allowed us to refine features based on real user needs.

Challenges and Solutions

One of the biggest challenges was optimizing battery usage while collecting data from various sensors. I implemented intelligent polling mechanisms that adjusted based on user activity levels, resulting in a 40% reduction in battery consumption.

Outcome

The app has been downloaded over 50,000 times with a 4.6/5 rating on app stores. Users have particularly praised the intuitive interface and personalized insights.
