Find what's actually driving your attacks — and get the data to prove it. Attacks blur together. There's no clean baseline to compare against, no obvious culprit, and no way to tell whether the wine, the weather, or the bad night of sleep was the one that did it. Most migraine apps are glorified diaries — you log the attack and the data goes nowhere. Migraine Help is a trigger-finding app first. TRIGGERS DON'T HIT ALONE — THEY STACK Rarely is it one thing. It's a pressure drop on top of short sleep on top of a cycle day. Migraine Help tracks how those loads pile up over time and shows which combinations precede your attacks — with honest confidence levels, so you know what's real and what's still a maybe. THE LIST GETS SHORTER, NOT LONGER Every attack is compared against your own non-attack days. That means suspects get cleared, not just added. Test one variable at a time and let the data confirm or rule it out, instead of cutting things out forever on a hunch. BAROMETRIC PRESSURE THAT ACTUALLY HELPS Pressure is the biggest driver for a lot of people. Migraine Help tracks it hour by hour and flags incoming shifts days ahead — proof your body isn't reacting for no reason. DOCTOR-READY REPORTS IN ONE TAP Headache days, identified triggers with confidence levels, hormonal patterns, medication effectiveness — a clean PDF your neurologist can read in 30 seconds. Useful for appointments, and for the documentation preventive treatments require. BUILT FOR THE MIDDLE OF A MIGRAINE One tap from the lock screen opens straight to a pain slider. Log a checkpoint, mark whether meds helped, done. WORKS WITHOUT A CYCLE Menopause, hysterectomy, pregnancy, postpartum, birth control — when cycle data isn't there, the engine leans harder on sleep, heart rate, and pressure. WHAT MIGRAINE HELP TRACKS Trigger correlation with honest confidence levels Trigger stacking and daily load Barometric pressure forecasts — incoming shifts, not just current readings Cycle phase and hormonal patterns Sleep, heart rate, HRV, and wrist temperature via Apple Health Medication effectiveness over time Payment charged to your Apple ID at confirmation. Subscription renews automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel in App Store account settings.

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.
