About
A flare and wound-care diary for hidradenitis suppurativa (HS) — called acne inversa across much of Europe and maladie de Verneuil in French-speaking communities — built to capture the details dermatologists actually ask about.
Track a flare in one pass:
• Affected zones across 11 body regions
• Hurley stage (remembered between entries — change it only when it changes) and IHS4 counts: nodules, abscesses, draining tunnels
• Pain, odor, and sleep-disruption sliders, active treatments, and time-to-heal
• Wound care entries for dressings and daily management
• Photos for visual history, 16 trigger types, menstrual cycle phase, and optional local temperature/humidity capture
• Medication doses and notes, plus an optional period-prediction reminder
Insights charts trend flares, pain, IHS4 and triggers over time; PDF reports and CSV export give your dermatologist the full picture between visits. Made for the HS warrior community.
Log from your wrist: an Apple Watch companion app is included for quick one-tap entries that sync to your phone.
Your data stays on your device — no account, no sign-up, and your health information is never uploaded to our servers. Export everything anytime as CSV or a PDF report.
This app is a personal tracking journal. It is not a medical device and does not provide medical advice, diagnosis, or treatment. Always consult your clinician about your care.
