Migraine patterns, privately.

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Quiet. Private. Built for iPhone. Hermly turns your Apple Health data into early signal patterns you can share with your doctor. A quiet migraine companion for iPhone. Hermly reads the signals you already collect in Apple Health — sleep, heart rate variability, cycle, the weather around you — and looks for patterns in the days before your attacks. Over time, it learns what tends to precede yours. So you can act earlier, and bring something useful to your next doctor visit. Built for women living with chronic or menstrual migraine. Designed for iPhone and the small moments when an attack starts. WHAT YOU GET Today's risk A single number on your home screen, based on patterns from your own past. No alarms. No red. Reverse insight In the first minute of setup, Hermly looks at the last 90 days of your Apple Health and proposes days that may have been attacks. You confirm what's true. Your baseline starts there. Attack Mode When a migraine begins, one tap turns on a Live Activity, dims your screen, enables a quiet Focus, and starts a timer. End it when you can. Hermly logs everything for later. Cycle awareness If your migraines cluster around your period, Hermly shows you when, in plain numbers. No assumptions, no advice — your data, your decisions. Doctor Report A structured PDF of your last 30 days for your neurologist. Frequency, trigger correlations, medication overview, topics worth discussing. Evidence Report A longer-window dossier — 6, 12, or 24 months — for disability claims, insurance, or workplace accommodations. PRIVACY Your health data never leaves your iPhone. Hermly does not run a server-side database of your migraines, your pain levels, your medications, or your cycle. The only thing kept on our servers is your subscription status, tied to an anonymous transaction ID — not to your name or email. Optional iCloud sync uses your iCloud Keychain for end-to-end encryption. We cannot read it. No ads. No data sale. ## NO MEDICAL CLAIMS Hermly is not a medical device. It does not diagnose, treat, cure, or prevent migraine. It is a personal health tracker that helps you see patterns in your own data and share them, on your terms, with the people who help you. ## Support & Feedback: Questions? Suggestions?
