Bar-o-Meter - Altimeter & Barometer

Very useful, also tell you GPS altitude and barometer altitude which means it will work without internet connection so you can use it to check altitude on a plane. It can also draw altitude/pressure graph for you. Many unit of measurement for pressure to choose from.

App is inoperable, needs update after 17.4 messed up access to barometer sensor. Using another app in the meanwhile. Great app otherwise when it's working.

Have used for several years, has been reliable and accurate. “Loved it.” Until the IOS 17.4 update, which sadly disabled fetching of data from the phone/tablet’s baro sensor. Getting station pressure was not possible*. IOS 17.4.1 helped, but alas, Bar-o-meter still does not function on my devices. There are some apps that now are functional for station pressure and other functions requiring an app to fetch data from the baro sensor on the device, not from a weather station on the web. *some users with unlocked phones and programming knowledge have posted workarounds, but if you have a carrier specific device like mine and can barely run your tv remote, that’s not an option.

How do I get the app to display actual pressure in inches of mercury instead of absolute pressure? Thanks.

Great site.

Not work for XR

WHY was my credit card charged AT ALL? This is supposed to be a FREE app unless I choose to upgrade!!! $20.77 ... BEWARE of this charge if you're going to download this app!!!

Use this app often. Works very well.

Needs to run in background. Needs to show the last 24 hours of pressure data. Add sun and rain icons to barometer to quickly indicate predicted weather. Needs ability to zoom out on the graph to see more hours at once without side scrolling. It would be cool if you could rotate the iPhone sideways so the graphs would be bigger and show more data at once. Needs Apple Watch support

Great app. You can make a lot of different choices. Best barometer app I have run across.
