Rosacea Sense

A private, on-device trigger analysis app for people managing rosacea.

Rosacea Sense helps users track daily symptoms, meals, exercise, and environmental factors to uncover patterns behind flare-ups. Using on-device statistical analysis and temporal flare detection, the app highlights foods and activities that frequently coincide with increased symptom severity — while keeping all data stored locally on the user’s device.

Built with SwiftUI and Apple Charts, Rosacea Sense focuses on privacy, simplicity, and practical insight. There are no accounts, no cloud storage, and no data sharing — just structured tracking and transparent analysis designed to support informed conversations with healthcare professionals.
