HabitTracker is a full-stack iOS habit and fitness tracking app built with SwiftUI, backed by a Node.js/Express, Docker and PostgreSQL API. Instead of a fixed layout, users can create themed folders and build their own dashboard using draggable, configurable cards for binary habits, numeric inputs, weekly and monthly charts, goals, notes, and progress photos. The app includes authentication, persistent user data, and a custom visual system designed to make personal tracking feel more flexible and engaging.
