The barometer on your iPhone is a tool that allows you to measure atmospheric pressure. Not only that, but it also helps you track your fitness. If you want to learn more about the benefits of the barometer and how to use it, you’ve come to the right place.
In this guide, I will provide you with all the information about the iPhone barometer, including ,how to use iPhone barometer?, what is barometer on an iPhone, what is the iPhone barometer sensor , The accuracy of the iPhone barometer, and iPhone barometer apps, among other details.
What is barometer in iPhone?
A barometer is a sensor built into your iPhone that measures atmospheric pressure. It estimates your altitude and supports various applications, such as fitness tracking and weather forecasting.
If the barometer needle goes up, it indicates that the weather is improving. If it goes down, it means the weather is worsening.
How Barometer app work on iPhone?
Many people enjoy knowing about weather predictions and are very interested in it. That’s why Apple has fixed the barometer app in all iPhone models from the iPhone 6 to the latest ones. With this app, you can easily predict the weather and track typical trends.
The barometer app tracks air pressure and comes in various types like Torricellian and aneroid, which were used in the past. Some of these are also fixed in your iPhone if you are an iPhone user; the barometer is built in.
iPhone manufacturers use the barometer to track GPS because it can significantly affect environmental results.
A barometer measures atmospheric pressure, which helps you estimate what might happen. If the barometer reading goes up, it means the atmosphere is improving.
If it goes down, it indicates that snow or rain might be coming. Today, we will explain how to use the barometer app on your iPhone.
You can easily download apps if it’s not built in, and find out everything about the weather before it happens.
How to use iPhone Barometer?
You can use the barometer app on your iPhone to check weather trends. For example, if you use the Barometer and Altimeter app on your iPhone, click “Set” to calibrate the red needle so it lines up with the black one. Over time, the black needle will move up or down, showing changes in the weather.
If the needle moves up, it generally means the weather is good. If it moves down, it indicates worsening weather or a chance of rain.
In addition to weather prediction, you can also check your current altitude. Remember, altitude and elevation are different: elevation is the height of the land above sea level, while altitude is how high you are above that land.
Your iPhone’s barometer can show your altitude (such as in a plane or on a hill), but it won’t tell you how far you are above sea level unless you know the land’s elevation.
Also, keep in mind that barometric pressure changes with weather and your location, so you need to set the reference altitude and pressure for accurate readings. Your barometric pressure should match the local pressure for correct altitude measurement.
Even if you don’t move, a change in atmospheric pressure will affect the altitude reading. To measure the correct atmospheric pressure, set the relative altitude to your current local altitude.
If you don’t change altitudes, the barometric reading will remain accurate. To check station pressure, you can set the reference altitude to zero.
Not just the iPhone, but you can also use Android sensors to get height readings. Basically, our goal here is to check small readings (zero or one) so that as soon as you change your height or position, you will know how much higher or lower you are.
Most people use these apps like to check height readings while traveling by pedal or for curiosity when moving from one place to another. There are many such apps available on the App Store. If your iPhone model supports it or not, you can easily access them
How to Access the Barometer Data?

How accurate is iPhone Barometer?
I was wondering if anyone knew what the actual accuracy of the barometer is in either the apple watch or the newer iPhone. I’ve searched around online and haven’t been able to find any detailed technical specs.
Two of the most accurate MEMS pressure sensors are the Bosch BMP388 which has .08 hPa relative accuracy or the even more sensitive TDK InvenSense ICP-101x series which has a relative accuracy of .01 hPa which works out to about .1 meter.
The relative accuracy is pretty good for MEMS based barometer and it is around 50 cm. The absolute altitude (from sea level) accuracy is poor and around 8-12 meter. The accuracy depends on the closing of sensor inside phone, weather etc. The app would be the factor.
Frequently Asked Questions
Does the iPhone 13 have barometer?
Yes, the iPhone 13 has a barometer because the barometer app started with the iPhone 6 and is available in all later models. To use it, go to your home screen and search for the app.
