Pressure Tomorrow? - Headache
Pressure tomorrow at a glance
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Four days of pressure changes at four levels, on the first screen. Log how you feel in two taps. Pro adds the evening alert, widgets and Apple Watch.
Pressure Tomorrow? shows people whose headaches and fatigue follow the weather how air pressure will change over the next four days, at four levels. Tomorrow's outlook is on the first screen. No graph hunting, no switching tabs.
WHAT IT DOES
• Four-day levels (Calm / Mild / Caution / Alert) with a short note such as "Falling tonight" or "Lowest tonight"
• Current pressure measured by your device's barometer, with the change over the last 3 hours
• A pressure chart from 7 days back to 5 days ahead
• Today's outlook on widgets and Apple Watch
• An alert one hour before a rapid pressure drop
• A "Feeling it" button. Choose intensity and type (headache, fatigue, dizziness, other); the time and pressure are saved with it
• Look back. A calendar and list show how your bad days line up with pressure
WITH PRO
• Evening alerts the night before a Caution or Alert day
• Tomorrow's outlook on widgets and Apple Watch; medium and large widgets show the next few days
• Pressure chart up to 10 days ahead
• No banner ads
Pro is available monthly, yearly, or as a one-time purchase. Every plan includes the same Pro. Watching an ad gives you Pro for 12 hours.
ABOUT THE LEVELS
Levels reflect the size of the pressure change. A drop of about 3 hPa within six hours shows Mild, 6 hPa Caution, and 10 hPa Alert. Sensitivity can be adjusted in three steps. The app does not predict or diagnose symptoms.
ABOUT YOUR DATA
Forecasts come from Apple Weather. Current pressure is measured on your device. Your entries are stored on this device, and headache, fatigue and dizziness entries are also written to Apple Health. Nothing is sent elsewhere.
