CalmSkin: Urticaria & Hives
Track Urticaria, Hives, UAS7
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Track your hives in 20 seconds. Get your UAS7. Walk into your appointment with proof. Now with improved sign-in and smoother tracking than ever.
Living with chronic hives ( urticaria ) means answering the same question
over and over: is my CSU getting better or worse? CalmSkin is a hives
tracker that turns daily check-ins into your weekly UAS7 score — so you
answer with data, not memory.
A HIVES CHECK-IN THAT TAKES 20 SECONDS
Hives count, itch, deep swelling (angioedema), sleep. Four taps, once a
day. That's it.
YOUR WEEKLY UAS7, CALCULATED FOR YOU
Every check-in feeds the Urticaria Activity Score (UAS7) — the same
weekly measure your dermatologist or allergist uses to track chronic
spontaneous urticaria. No maths, no spreadsheet. Just this week's score
and whether it moved.
SEE WHAT'S ACTUALLY CHANGING YOUR HIVES
Trends show your UAS7 week over week, with markers for the days you
started a medication or changed a dose — so a change and its effect on
your wheals and itch sit on the same line.
FLARE PHOTOS THAT STAY PRIVATE
Attach a photo to any day's log, tagged by that day's severity. Your
hive and rash photos are stored on your device and never leave it.
MEDICATIONS, BIOLOGICS & INJECTION CYCLES
Log antihistamines and biologics like Xolair (omalizumab), get
reminders, and track where you are in an injection cycle — including
the average symptom level across the cycle.
A UAS7 REPORT FOR YOUR NEXT APPOINTMENT
Export weeks of check-ins as a clean PDF. Bring your dermatologist or
allergist the whole picture instead of trying to remember last month.
AI WEEKLY INSIGHT
A short written summary of your week — what moved, what held steady,
what's worth mentioning at your next appointment.
BUILT AROUND YOUR PRIVACY
Your urticaria log lives on your device. Lock the app behind Face ID or
Touch ID, export everything you've recorded at any time, or delete all
of it in one tap.
CalmSkin is a symptom diary for chronic hives and urticaria. It does
not diagnose any condition and is not a substitute for advice from a
qualified healthcare professional. Always talk to your doctor about
your symptoms and treatment.
