The Breathing App was created to help individuals establish consistent relaxation practices through guided breathing exercises. The project included step-by-step guidance for multiple techniques, interactive tests, and progress scoring, providing educational and practical value. Before this project, resources for learning and practicing breathing exercises were scattered and lacked interactivity, making consistent progress difficult. My goal was to create an engaging, interactive mobile platform, ensuring accessibility, clarity, and actionable feedback. The final result is a cross-platform application built with .NET MAUI and Firebase, combining guided exercises, test-based feedback, and progress tracking to create an effective mindfulness experience.
