## What is Barometer Plus?

Barometer Plus app measures air pressure and altitude using your device's built-in barometric pressure sensor.
Because air pressure changes usually indicate a weather change, you can use this app to monitor and predict short-term weather variations.
People suffering from migraine, headaches, or joint pain can monitor how barometric pressure impacts their mood.
Fishermen can monitor the atmospheric pressure for right-time fishing.

FEATURES:
• The app contains a barometer and altimeter with a personalization graphic in classic analog style. It also displays the current temperature and humidity.
• Display barometric pressure (sensor value) or mean sea level pressure (MSLP - value used in weather forecast services or stations).
• Units support for pressure: mb, inHg, kPa, atm, Torr, psi, hPa, mmHg. Units for altitude: meter, feet.
• Calibrate the barometer using altitude/location from the GPS. Calibrate the altimeter using the nearest airport information/METAR, or manually enter the QNH of the nearest airport. Offset sensor output value.
• Measure the height (building/mountain/hiked/climbed) using the "Relative Altitude" feature (can be enabled in the app's Settings).
• Notification about pressure change. "Notification custom rule" for you to define how and when the app sends notifications.
Notify when air pressure changes indicate that extreme or worse weather may occur.
• "Pressure Tracking" and "History Graph" require "Background App Refresh" or "Always Location Service" with "Exact update interval" enabled.
• "My Area" allows you to define your frequent stay places, and the app tracks air pressure with location data.
• Export history to CSV format and Today widget.
• This app is the digital version compared with an aneroid or mercury barometer and can be adjusted to MSLP with additional features.

CUSTOMIZABLE:
You can change your barometer/altimeter appearance with:
• Seven different housing colors.
• Black, white or blue disk background.
• Four different app backgrounds.
• Three different types of needles.
• Marker needle for easily monitor.
• Dark or light Today widget theme.

NOTES:
• App only works on devices with a barometer sensor, such as iPhone 6/6s/7/8/X/11/12/13 (including Plus models), iPad Mini 4/Air 2/Pro, or later.
• Weather icons on the dial: This only shows the air pressure trend like in an analog barometer.
• Each time your device reboots, open the app for tracking with the "Exact update interval" feature work.
• You may take the phone/tablet far away from computers, cables, and other magnetic sources to get accurate results.
• This app is Pro / Premium version of the "Barometer Plus - Altimeter" app, only difference is all feature unlocked and no ads. If you already use the "Barometer Plus - Altimeter" app and purchased in-app, do not need to purchase this again.

### 4/5 — Need to keep app open to keep history

*2026-03-20, version 3.7.8*

Nice simple app. I’m disappointed that the history disappears for the days I forget and close the app. Super inconvenient to always need to have it open to keep history current, the whole reason I have this app.

### 1/5 — Lord trustee PAOLO

*2026-03-15, version 3.7.8*

Yes pls

### 5/5 — This is a great tracker

*2026-02-21, version 3.7.8*

Works with real air pressure or barometric pressure. No forecasting feature though

### 1/5 — Barometer

*2026-01-03, version 3.7.8*

Wish it would show an arrow pointing up or down in the barometer widget.

You have no way of knowing whether the atmospheric pressure is currently rising or lowering, and yes, I have Settings for every four hours to get notified but would be nice to see it on the widget, otherwise what’s the point of having a widget if it doesn’t give you the information you want and need.🤷‍♂️

### 5/5 — Aiguille

*2025-12-30, version 3.7.8*

L’aiguille quide est difficile à placer ça serait bien d’avoir seulement un toucher pour qu’elle se place 
J’aimerais avoir le suivie de la lune

### 1/5 — Works, but not without severe compromises to one’s privacy

*2025-11-03, version 3.7.8*

See title.

### 3/5 — Works, but not without work-arounds

*2025-10-15*

I have to open once, close and open a second time for it to update graph data. Odd.

### 5/5 — Works well, compatibility issues corrected.

*2025-10-13, version 3.7.8*

I used to use this app to compare the changes in pressure with my health issues. I had to update the App's rating to 5-stars now that it has been updated. Previously, there were several problems using it on my iPad. Since then the App has been fixed and back to what I had once enjoyed. Anyway it is now  compatible with my current version of the iPad OS and hope it stays that way.

### 1/5 — Экран

*2025-10-05*

Приложение не работает. Не отображает никакие данные.

**Developer response:** Hello, you can try delete and reinstall the app

### 5/5 — This app needs motion data enabled on phone

*2025-07-31, version 3.7.7*

I didn’t realize it, but this app needs to have motion enabled for motion and fitness in your settings privacy so once you do that the app works great but before that it’ll just look like it’s doing nothing.  Despite the age of the app, it works really well and it has options for a little bit more control into what is tracked so I like it because it’s you know doesn’t need location on all the time and I feel like it’s pretty decent and the app is from Vietnam
