From install to your first forecast: what happens, in what order, and why.
1. Grant permissions
During onboarding Migraine Sentry asks for four permissions. Each one powers something specific, and each can be skipped and enabled later in Settings:
- Health data: reads sleep, HRV, heart rate and the rest of the signals your devices already record. This is the heart of the app.
- Motion & barometer: your iPhone's pressure sensor, for tracking barometric changes.
- Location: approximate only (about 1 km), used solely to fetch local weather and pressure forecasts.
- Notifications: morning forecasts, signal nudges, and optional reminders like the daily check-in and post-migraine follow-up.
2. Your first week
From day one, the Today tab shows your live signals. Behind the scenes, Migraine Sentry imports up to 90 days of your existing Apple Health history, so your personal baseline often exists within minutes, not weeks. The setup card on the Today tab shows exactly where you are:
- Learn your baseline: 7 days of health signals establish your normal.
- Log 3 migraines: one tap on the + when an attack begins. Details can wait.
- Your forecast turns on: once both are done, forecasts arrive each morning.
3. Log your first migraine
When an attack starts, tap the large + button and confirm. That's the only thing Migraine Sentry ever asks of you mid-attack. When it ends, tap stop; a short follow-up survey (severity, symptoms, medication, suspected food triggers) fills in the picture whenever you're ready.
4. The daily check-in
Once a day, 30 seconds: caffeine, alcohol, hydration, stress, meals. These are the triggers no sensor can see, and they sharpen everything else. More on check-ins →
