When today starts to drift from your baseline, Migraine Sentry says one quiet, useful thing, then stops.
What fires a signal
Through the day, Migraine Sentry watches signals that research and your own history connect to attacks: barometric pressure falling, activity collapsing, a temperature swing, your perimenstrual window opening, a stressful stretch suddenly easing. When one crosses your personal threshold, a signal appears in the tray on the Today tab.
The colours
- Amber: worth knowing. A heads-up, not a warning.
- Coral: higher priority. A signal has crossed its more serious threshold.
Neither means a migraine is coming; signals get more personal as you log attacks and the app learns which ones matter for you.
Designed not to nag
- One nudge per signal per day, maximum.
- Every nudge pairs the observation with an action: "hydrate, protect sleep tonight," not just "pressure dropping."
- Dismiss a signal with its ✕ and it stays gone for the day.
- All nudges are automatically silenced during an active migraine.
Notifications for nudges can be toggled independently of the morning forecast in Settings → Proactive alerts.
