See barometric pressure next to your migraine history.
Migsy shows the next 24 hours of barometric pressure, humidity, and temperature, with location permission, beside your logged migraine attacks. The point is not a magic forecast. It is to see whether weather shifts actually line up with your days.
What the 24-hour view includes
With location enabled, the forecast screen shows pressure, humidity, and temperature signals for today and tomorrow, plus a risk score that also uses your own attack history. You still log the attack in the migraine diary. Weather is context, not a substitute for the log.
Why “migraine weather app” is a crowded search
Apple Search for barometric pressure and migraine weather is full of dedicated barometer apps and of Migraine Buddy’s seven-day weather tools. Migsy is not trying to be the only barometer on your phone. It is the neurologist-built diary that already has weather risk on the same home screen as your week of attacks.
| If you want | A reasonable fit |
|---|---|
| Pressure alerts only | A dedicated barometer or WeatherX-style forecast |
| Diary + community + Android | Migraine Buddy |
| Diary + 24h pressure + doctor report on iPhone | Migsy |
Limits
Pressure data depends on location permission and network. Risk scores can be wrong. Do not skip prescribed treatment because a screen looked calm. Migsy is not a medical device and does not diagnose weather-triggered migraine.
Frequently asked questions
Can barometric pressure trigger a migraine attack?
Many people with migraine report attacks around weather and pressure changes. The link is real for some and overstated for others. A useful app shows local pressure next to your own attack history so you can see whether the pattern holds for you, rather than treating a generic forecast as fate.
Does Migsy forecast migraine from the weather?
Migsy shows barometric pressure, humidity, and temperature signals for the next 24 hours, with your permission to use location, and a risk score that also uses your logged history. It is an early-warning view, not a guarantee that an attack will or will not happen.
How is this different from WeatherX or Pressure Pal?
WeatherX and Pressure Pal are built around pressure and weather alerts. Migsy is a full migraine diary that also shows 24-hour pressure and weather next to attacks, medications, and a doctor report. If you only want a barometer, those apps may be enough. If you want the log and the weather in one iPhone app, that is the Migsy case.
Do I need a subscription for weather risk?
Migsy is free to download on iPhone. Ongoing tracking — history, stats, calendar, doctor-ready reports, and weather risk — requires Migsy Pro, billed through Apple. A free trial is offered in the app; check the current price on the paywall before you subscribe.
