BaroNote
Check current air pressure and its trend on your iPhone, then log how you feel — all stored on device.
Overview
BaroNote is a simple barometer and personal log for iPhone. It reads the current air pressure from your iPhone's built-in pressure sensor, shows whether pressure is rising, steady, or falling, and lets you save a quick private note about your mood and physical condition alongside the reading.
Many weather apps bury pressure data under forecasts and ads. BaroNote does the opposite: one clear pressure reading, a simple trend, and a lightweight log, with no forecast, no account, no tracking, no ads, and no server upload. Your records stay on your device, and the app deliberately avoids medical claims: it is for personal logging only and does not provide medical advice, diagnosis, treatment, or forecasts.
In History, BaroNote places the available six-hour pressure movement beside each log without judging the cause. Health linking is optional and off by default: when you turn it on, BaroNote writes your headache, fatigue, and (on iOS 18 or later) mood records to Apple Health. It does not read Health data.
Home Screen and Lock Screen widgets show the current pressure and trend at a glance, so you can check pressure without opening the app.

Privacy
Your BaroNote records stay on this device: pressure readings, mood and condition logs, symptom tags, notes, and settings are stored locally and never uploaded to a server. There is no account, no cloud sync, no tracking, no ads, and no analytics SDKs. Widgets read a local snapshot shared only between the app and its widget extension. Apple Health linking is optional and off by default; it only writes the supported items (headache, fatigue, and mood on iOS 18 or later) and never reads Health data. You can delete all local data from Settings at any time.

Does BaroNote forecast the weather or predict headaches?
No. BaroNote shows measured pressure and a simple rising/steady/falling trend. It provides no forecasts, no diagnosis, and no medical advice. It is for personal logging only.
What can I record in a log?
Each entry can include mood and condition (good/normal/bad), symptom tags such as headache, sleepy, tired, low focus, and stiff shoulders, plus an optional note. The current pressure is saved with the entry.
Does BaroNote connect to Apple Health?
Optionally. Health linking is off by default. When you turn it on, BaroNote writes headache and fatigue records, plus mood on iOS 18 or later. It does not read Health data, and sleepiness, low focus, stiff shoulders, pressure, and notes are not written to Health.
