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 API, no location tracking, no account, and no server. Everything you record stays on your device, and the app deliberately avoids medical claims: it is for personal logging only and does not provide medical advice.
Home Screen widgets show the current pressure and trend at a glance, and Lock Screen accessory widgets are available on supported iOS versions, so you can check pressure without opening the app.
Who It Is For

- Anyone who wants a plain barometer reading without a full weather app

Privacy
All data stays on your device: pressure readings, mood and condition logs, symptom tags, notes, and settings are stored locally and never sent to a server. There is no account, no cloud sync, no tracking, and no analytics or advertising SDKs. Widgets read a local snapshot shared only between the app and its widget extension. You can delete all local data from Settings at any time.

Everything stays on your device. BaroNote has no account, no cloud sync, no server communication, and no tracking or analytics. You can delete all local data from Settings.
Does BaroNote work on every iPhone?
The pressure reading uses the iPhone's built-in barometric sensor. On devices without a pressure sensor, the app shows an unavailable state. BaroNote requires iOS 17 or later.
Does it have widgets?
Yes. Small and medium Home Screen widgets show current pressure, trend, and last log status, and Lock Screen accessory widgets are available on supported iOS versions.
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 health guidance — it is for personal logging only and does not provide medical advice.
What can I record in a log?
Each entry can include mood (good/normal/bad), condition (good/normal/bad), symptom tags such as headache, sleepy, tired, low focus, and stiff shoulders, plus an optional free-text note. The current pressure is saved with the entry.
