About Migraine Sentry: Forecast
Know before the pain, without logging everything. Most migraine trackers ask you to record everything. Migraine Sentry works differently. It uses Apple Watch, Apple Health and weather data to build a picture of your personal baseline. Your devices collect the signals. You log the migraine. Migraine Sentry connects the two. Once your baseline is ready, each morning brings a simple Low, Moderate or Elevated vulnerability forecast. Look seven days ahead for pressure-related and cycle-related risk. As your history grows, Migraine Sentry explains what changed before your attacks, ranks the signals most closely linked to them and shows which treatments appear to work best for you. WHAT YOU GET • A personal migraine vulnerability forecast each morning • A seven-day outlook based on weather, pressure and your own patterns • Passive analysis of sleep, HRV, resting heart rate, activity, wrist temperature and more, where available • Personal trigger rankings based on attacks and normal days • Plain-language explanations of what differed from your baseline • Fast logging from iPhone or Apple Watch, with an active migraine shown through a Live Activity on your Lock Screen • Optional check-ins for stress, hydration, caffeine, alcohol and skipped meals • Cycle awareness for cycle-related patterns, if you choose • A clear clinical PDF for your doctor or neurologist HOW IT LEARNS Log a migraine and Migraine Sentry captures the surrounding context. After several attacks, it begins surfacing emerging patterns. With more history, it becomes better able to distinguish signals that appear before your migraines from signals that are also common on normal days. NO APPLE WATCH? You can still use migraine logging, iPhone pressure readings, weather, check-ins, history and reports. Compatible wearables that write sleep and heart-rate data to Apple Health can provide additional signals. PRIVATE BY DESIGN Raw Apple Health readings are processed on your iPhone and never sent to our servers. Migraine entries and settings can back up through your private iCloud account. Migraine Sentry does not operate a migraine-data server. FREE AND PREMIUM Migraine logging, history, check-ins, your daily forecast level and the core clinical report are free. Migraine Sentry Premium adds the reasons behind your forecast, live signal nudges, detailed seven-day outlook information, personal trigger rankings, pattern and treatment insights, and expanded report analysis. Every new user receives a 21-day full-access Premium Preview once their forecast is ready. The preview does not start a subscription or renew automatically. Premium is an auto-renewing subscription with a 21-day full-access preview for every new user. Payment is charged to your Apple Account at purchase confirmation. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel anytime in Settings. Migraine Sentry is not a medical device. It does not diagnose, treat, or prevent any condition. Forecasts and insights are informational only. Always consult your healthcare provider about your migraines.

What’s new
Version 1.2.1 · Updated October 19, 2026
What else helped, your migraines in Apple Health, and a check-in that fits you. WHAT HELPED BESIDES MEDICATION The post-migraine survey now asks what you reached for: sleep, a dark room, cold, heat, caffeine, water, fresh air, or anything of your own (Profile > Custom Items > Reliefs). Each attack shows them on its page. The Treatment tab counts how often you use each one and, once a relief has ten attacks with it and ten without, tells you whether those attacks ran shorter. The clinical report lists them on its Treatment page. YOUR MIGRAINES IN APPLE HEALTH Turn on "Write migraines to Health" under Profile > Permissions and every ended migraine is recorded in Apple Health as a Headache symptom with its start, end and severity, including the ones you already logged. Editing an attack updates its entry, deleting one removes it. Off by default, and switching it off later leaves Health as it is. A CHECK-IN THAT FITS YOU Never drink, or never have caffeine? You can now hide that question. After a week of answering "none" in a row the check-in offers it once; the switches live under Profile > Custom Items > Built-in check-in questions. A hidden question is recorded as none each day, so your streak and completeness are unchanged, and the Insights trigger list says the signal is switched off rather than untested. SMARTER CAFFEINE SIGNALS Caffeine withdrawal is only tested once you have caffeine on most days. For an occasional drinker a coffee-free day is not a signal, and the Insights coverage list explains that. New signal: High caffeine, three or more drinks the day before an attack, backed by a prospective study of people with episodic migraine. The check-in now says what High means. ALSO - The morning forecast's "attack yesterday" treats a night that ended after midnight as the night before, like the rest of the app. - Delete confirmations say exactly what is removed, including any Health entry this app wrote. - Clinical report: long medication names no longer push the Treatment page off its footer. - Profile > Custom Items is reorganised: your own check-in questions and the built-in ones are now two clearly named sections.
