iPhone
See your flares mapped on your body, log stress, sleep, and weather alongside them, then hand your dermatologist a report that shows exactly where and how often.
Your elbows flare every spring. Your hands flare after dishes. Your scalp never seems to fully settle. On their own those look like separate problems — until you can see them on one map.
Fibrolog draws every flare onto a simple body outline, so the areas that keep coming back — hands, elbows, scalp, wherever it hits you — show up as a picture instead of a scattered list of dates.
WHAT YOU CAN DO
- See your flares mapped onto your body: a heat map of the areas that come back most, built from your own history
- Log a flare in seconds — severity, itch, symptoms, affected areas, and photos
- Note the stress, sleep, and cycle days that sit alongside a flare, context that's easy to forget by the time you sit down to log
- Track exposures across food, products, weather, fabric, and more
- Watch your clear-skin streak build, and see whether flares are settling or picking up (Clear-Skin Recap)
- Spot which logged exposures tend to show up before your flares (Premium)
- Export a doctor-ready PDF summary before your next appointment (Premium)
FREE — NO ACCOUNT NEEDED
