## 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" (paid feature) 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 (paid features).
• 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.

### 5/5 — Works brilliantly

*2026-08-04, version 3.7.6*

Fab app, cheap to go add free too. Great for knowing when a drop or rise in pressure might trigger a migraine.

### 3/5 — History graph often not available

*2026-07-30, version 3.7.6*

Was very happy with the app, however, recently the history graph has not been working. As I found this a very helpful feature it’s frustrating that it doesn’t display all the time

### 3/5 — Good - could be great

*2026-06-17, version 3.7.6*

The app concept is great. Slightly outdated design but has some really good ideas to make this one of the best ones in the App Store for simple barometric monitoring like history, a main face dial that shows acceptable ranges and typical weather at that pressure, custom notifications etc. 

What could be improved:
History chart doesn’t match up with the live view. It’s regularly a whole point off (29.x instead of 28.x) in the chart. For better ux, using a curve instead of linear lines would be nicer to see. 

For notifications, sometimes you click on one and it opens the app but there is no way to see what that notification was or specifically when it happened so you’re not sure if it was an old one or not. Having the notifications from the app stored with timestamps would be great. 

Lastly, Sea level adjustment via gps is nice but would be better to track live altitude adjustments while traveling using the internal tools of iPhone instead of map data to make the adjustment live. Perhaps it does this but I just notice if I have it up and travel it thinks my pressure has changed when it’s just a different altitude.

### 2/5 — Great at first

*2026-06-13, version 3.7.6*

Loved this app and then it just stopped working. Deleting and looking for a new one.

### 2/5 — get rid of ads & you have a good app

*2026-06-13, version 3.7.6*

The app is ok, but the ads are wayyyy too much. When you open the app there’s several ads, just checking the pressure ads pop up. It’s just way too much. I understand it’s free, buts just too much. I would not mind paying a few dollars. But I haven’t seen that option.

### 1/5 — 全画面の動画広告

*2026-06-10*

使い始めて1分で2度も挟まってきた全画面閲覧強制動画広告。
Very frequent full-screen un-skippable Video Ad.
Worst experience ever had.
Useless.

### 5/5 — Best barometer

*2026-05-23, version 3.7.6*

This barometer is pretty accurate and useful when you want to know what the actual weather conditions are like and if it’s good to take the boat out onto the bay!

### 2/5 — Disappearing markers

*2026-05-08, version 3.7.6*

Needles have disappeared. Tried re-loading the App, but nothing changes. Totally useless right now to be honest

### 3/5 — Great app, fatal ad strategy.

*2026-05-06, version 3.7.6*

Developing an app is expensive. And developers like to make money. It’s the system we are in: ads pay for stuff. I get it. 

This app, though, grabs the entire screen, and all audio, so frequently and so aggressively that the app isn’t useable; can’t run it long enough without full screen and audio take over. 

There are lots of ways to use ads without alienating users. Let’s hope this excellent developer gives monetization a re-think.

### 5/5 — New User

*2026-03-02, version 3.7.6*

I have only had the app for a few days and I am kind of impressed. I am trying to tie the relationship of barometric pressure to some medical issues. I find that the dial is easy to read and I get informative notifications when there will be changes. Thank you!
