Pulse Harmony Sync is an Android application designed to assist users with manual wellness monitoring and breathing exercises. The app features a visual breathing guide that utilizes timed cycles for inhalation, breath-holding, and exhalation, facilitating effective breathing practices. Additionally, it includes a heart rhythm logger that estimates beats per minute (BPM) based on five consecutive manual touch inputs, providing users with valuable insights into their heart health.

The application also tracks user engagement with a statistical streak tracker, which calculates consecutive days of interaction based on local activity logs. Users can view a chronological activity feed that displays a history of completed breathing and rhythm sessions. Notably, all data processing occurs on the device, ensuring privacy and accessibility without requiring network access. The calming interface is designed with a minimalist aesthetic, featuring earth-toned color schemes that enhance the user experience.
