BARO: Barometric Pressure
Migraine & headache forecast
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
See pressure changes coming and track how you feel. Your symptom logs stay on your iPhone. Free download with a one-time Pro upgrade.
Some people feel the weather before it arrives. BARO turns the barometric forecast into one number you can read in two seconds, tells you when the change is coming, and — as you log how you feel — learns the pattern that is yours alone.
TODAY
• A 0–100 Body Weather Risk with a plain-language reason
• The window when conditions look hardest, not just "today"
• A 24-hour pressure curve with the elevated stretch shaded
• Pressure, humidity, temperature and your own sensitivity setting
BEFORE IT ARRIVES
• Alerts scheduled on your iPhone from the forecast BARO already downloaded
• A separate alert for sharp three-hour pressure swings
• A morning summary you can answer with one tap
ONE-TAP CHECK-IN
• Nine presets from Good to migraine, with optional intensity and a note
• Every entry stores the weather that was happening at that moment
• Log a good day straight from the notification, without opening the app
YOUR OWN PATTERN
• How often your symptoms follow falling pressure
• The pressure threshold that matters most for you, shown with the tally behind it
• Pressure, humidity and temperature ranked by how strongly they line up
• 30 / 60 / 90-day views
WIDGETS
Home Screen and Lock Screen widgets read the score BARO already calculated — no extra battery or data use.
PRIVATE BY ARCHITECTURE
No account. No BARO server. No analytics SDK. Your check-ins live on your iPhone and are deleted with the app. Weather comes from Apple Weather; your location is used to request it and nothing else.
BARO PRO — one purchase, no subscription
The full 7-day forecast and day detail, the complete Insights analysis, alerts across the whole horizon, every widget style, and unlimited visible history.
BARO provides weather-related wellness information and personal pattern tracking. It is not a medical device, a diagnosis, a prediction of a medical event, or a substitute for professional medical advice. If you have severe, sudden, unusual or concerning symptoms, seek appropriate medical care.
