CalmSkin: Urticaria Tracker

Track chronic hives. Walk into your appointment with proof.

CalmSkin is a symptom tracker built for one condition: chronic urticaria (hives). Instead of trying to remember how bad your week was, you log it in about 20 seconds a day — and CalmSkin turns it into UAS7, the urticaria activity score your dermatologist or allergist already uses.

WHAT YOU LOG IN 20 SECONDS
• How many hives (wheals, welts) in the last 24 hours
• How intense the itch is
• Whether you had deep swelling (angioedema)
• How you slept

YOUR UAS7, CALCULATED FOR YOU
UAS7 is the Urticaria Activity Score over 7 days — a 0 to 42 scale where lower is better. CalmSkin scores every check-in and rolls seven days into the weekly number clinicians ask for. No maths, no spreadsheets.

SEE WHAT IS ACTUALLY CHANGING
• Weekly UAS7 over 30 days, 3 months or a full year
• Change markers that pin the day you started or stopped a treatment, so you can see the before and after
• A cycle view for long-acting biologic injections — spot whether symptoms creep back before your next dose

A PHOTO LOG THAT STAYS PRIVATE
Attach flare photos to any day. They are stored on your device and never uploaded. Tap a day to see the scores that go with the picture.

MEDICATIONS AND REMINDERS
Keep daily antihistamines and long-acting injections in one plan. One gentle daily reminder to check in, plus medication reminders — all scheduled on your device.

A DOCTOR REPORT WORTH HANDING OVER
Export a clean PDF: average UAS7, change across the period, days logged, symptom-free days, weekly scores, your medication plan and your treatment changes. The clinical language your doctor already speaks.

ASK YOUR OWN DATA
The built-in assistant reads only what you have logged, and always shows which entries an answer came from — check-ins, photos, medications, treatment changes. Ask whether an antihistamine is helping, or what to bring to your next appointment.

PRIVACY BY DEFAULT
• Your check-ins and photos stay on this device
• No account required
• Optional biometric lock (fingerprint or face)
• Export everything, or delete everything, whenever you want
