Migraine Sentry: Forecast

Tired of guessing what sets off your migraines?

Most migraine apps make you log everything by hand: every meal, every bad night's sleep, every headache. And they still leave you no closer to an answer. Migraine Sentry works differently. It reads the health data your iPhone and Apple Watch already collect and quietly looks for the patterns that come before your attacks, so the tracking happens on its own.

Over time, Migraine Sentry learns your personal baseline: your normal sleep, heart rate variability, activity, and the weather around you. When today starts drifting away from that baseline, it notices. Each morning it shows a simple vulnerability forecast: Low, Moderate, or Elevated. When several signals move at once, it can nudge you early, while there's still time to rest, hydrate, or head off a hard day.

WHY IT'S DIFFERENT • Passive tracking. No daily logging required; your Watch and phone do the work. • Built for Apple Watch: sleep, HRV, resting heart rate, blood oxygen, wrist temperature, noise exposure, and more. • No Apple Watch? Wearables that sync sleep and heart rate to Apple Health work too, with fewer signals. Pressure, weather and check-ins need only your iPhone. • Your week ahead: a 7-day risk outlook built from the pressure forecast and, if you track it, your cycle. Premium adds the day-by-day reasons and an evening-before heads-up when a sharp pressure drop is coming. • Private by design: health readings are analysed on your iPhone and never uploaded, not even to iCloud. What you log backs up only to your own private, encrypted iCloud, never our servers. • A vulnerability forecast every morning: Low, Moderate, or Elevated. • Personal trigger ranking. See which signals actually precede YOUR migraines, scored against how often they show up on normal days. • Barometric pressure tracking. The phone's own sensor catches the rapid pressure drops that weather apps smooth over. • An optional daily check-in for the things sensors can't see: stress, water, caffeine, alcohol, skipped meals. • Optional menstrual-cycle awareness for perimenstrual patterns. • A clean clinical report (PDF) to share with your doctor or neurologist.

HOW IT LEARNS Log a migraine and Migraine Sentry captures a snapshot of your health data around it. After a handful of attacks it surfaces emerging patterns; with more, it ranks your personal signals by how specifically they precede your migraines versus normal days. The more you use it, the sharper it gets.

Migraine Sentry is designed for people with migraine who want to understand their condition without turning tracking into another chore.
