Itchwise: Eczema & Skin Diary

Stop guessing what triggers your skin.

Log your day in 10 seconds — itch level, sleep, affected areas, and suspected triggers from a 39-item library (foods, environment, body & mind, contact & habits). After 3 weeks, Itchwise shows which factors are statistically associated with YOUR flares: exposure vs baseline, confidence intervals, honest statistics — never medical claims.
