HS flares are unpredictable and hard to describe in a short appointment. HSDiary keeps logging quick and private — symptoms, lesion sites, triggers, and treatments — so months of daily reality become one clear picture you can share with your dermatologist.
Highlights
- Track lesion sites, flare severity, triggers, and treatments day to day
- Spot what precedes a flare — food, stress, cycle, friction, or something else
- Private and discreet — sensitive details stay on your device, no account to start
- Clinician-ready summary so your appointment stays focused on decisions
HSDiary is for the day-to-day reality of living with Hidradenitis Suppurativa — the flares that arrive without warning, the careful watching of what might have triggered them, and the appointments where it can be hard to convey how much has happened since the last visit.
It keeps logging quick and unobtrusive: note a flare, mark where, record what you tried, flag a possible trigger. Over time the app surfaces patterns — the connections that are hard to see day to day but matter when you’re talking treatment strategy with your dermatologist. Export a clean summary before your next visit so the conversation can focus on what to do next, not what you can still remember.
HSDiary is for logging and insight only — it does not provide a diagnosis or medical advice.

Appointment-ready export
Generate a clean PDF or CSV before your visit — months of detail condensed into what your dermatologist actually needs to see.
Your privacy
Your health data stays on your device by default — local-first, no account required to begin. Sensitive details about your skin and symptoms never leave your device unless you choose to export them. helperly.org never sells your data. HSDiary helps you log and understand patterns; it does not provide a diagnosis or medical advice. The free version is ad-supported through Google AdMob, which applies its own ad tracking; upgrade to remove ads.
