An app that turns "today feels heavy" into something you can actually look at: how much the conditions overlap.
Download on the App StorePick one of four levels and note whether you took medication. Pressure, sleep and heart data are collected for you and treated as that day's conditions. As entries add up, you see — in days, not percentages — which conditions line up with how you feel.

Your entries and health data stay on your device and are never sent anywhere. Only weather data is fetched, from Apple's weather service.
Health data is read only — the app never writes to Health. Notifications never name a symptom, so nothing sensitive shows on your Lock Screen.
This is a wellness app that shows how your own entries relate to weather and health data. It is not intended for the diagnosis or treatment of any condition, and it does not provide medical advice. The index is a rough measure of how much conditions overlap, not a statement about what will happen. If you are concerned about your health, please talk to a healthcare professional.
If you have sudden severe pain or symptoms that feel unusual for you, please contact a healthcare professional.
Requires iPhone (iOS 26 or later). Apple Watch optional. Available in 36 languages.
