Does not update in the backgroud. The widget has dark text in dark mode. No support for IOS 14 widgets. Graph mode is missing close/back button.

The barometer itself is fine. But...if you select the graph, or settings, there appears (on my iPad) to be no way of getting away from the selection! I’ve tried everything, but I end up having to close it down and then reopen. What a pain!

Pressure readings do not correlate with live aviation reported levels. Sea level pressure is always lower than actual level which cannot be right.

Consistently hows sea level pressure (aviation QNH) as lower than 'absolute' (station) pressure (QFE). That is possible at very few places on earth. App is consistently applying correction for elevation ('altitude') in wrong sense.

This app works very well. Easy to read and relatively accurate. Also tested in a light aircraft at 2000 feet and was spot on pressure and altitude wise.

This is one of those apps where there is no doubt the developer can do the job, but they just fall down on almost every other aspect. Bar-o-meter is not much more than proof of concept at this stage and can hardly be regarded as a satisfying 'go-to' app to use. Completely flat in appearance the GUI is wholly underwhelming. As a reviewer pointed out a year ago now, the needlessly massive scale range renders the visuals difficult because one cannot deduce the pressure in a nice more traditional sense by looking at the dial. It does have things going for it. Several in fact, but my attempts to engage with the developer have sadly come to nothing so far. Sometimes what is needed is a team of different skill sets to make something work before bringing to market. But all too often the originator or pioneer doesn't have those additional skill sets on board, and more seriously, doesn't pursue them. When those capable of advising from the side lines are ignored, it is a good indicator the developer lost interest, even those this app was or should have been to showcase skills. Under the less ridiculous name of 'Barometer'; can't think of the logic behind that name (who is going to find it unless by accident) there are other very nice choices that will do it for you, whether you can read the air pressure in your device directly or whether you simply use a device that obtains the data from the weather station outlets, which there are sure to be one or more within a few miles of you. Much could be done to improve this app. It's like a company needing amalgamation or take over, but it's hardly worth paying to have the ads removed to look at it with a little less pain for the eyes. Perhaps it was only ever about the ads. I do believe that criticism should be just and should be constructive, and never meant to denigrate a developer who put a lot of time into something but came up short for reasons we cannot know why. Personally, I think that is what has happened here. I'd like to see the developer make a success of it. S/he could privilege it in alternative versions such as one that might be of use to pilots, this wide measurement scale is much more suited to that kind of application if the scale is rotated so as to be suited for reducing air pressure at altitude. If you think you can help this developer out with really constructive focussed and useful ideas to make this the 'Bar-o-meter' s/he always intended, do please help out. The areas of use would be how to

This app was just what I was looking for, but sadly it does not work on my iPad 3 running iOS 8.3.

The app is lovely and doesn't treat you like an idiot like some of the others do!

This only works on the iPhone 6 and 6 plus obviously as they have a pressure sensor. This seems to be the best app and gives fast results as well as charts. Recommended!

At present the pressure shown is the absolute pressure at the height of the device. For weather station purposes the pressure corrected to sea level is normally used, so for example today at my home at a height of 200 ft above sea level with an absolute pressure shown as 999mB, the sea level pressure would be approx 1006mB. (This was calculated using an online calculator).The result compares well with my own weather station barometers and the local airport. Please can this simple calculation be added to the application. I do not understand the altitude from pressure reading given, as that cannot be known unless you know what the pressure is accurately at sea level. I assume that you are using some standard pressure which of course will hardly ever be correct. So the altitude calculated this way is pointless and totally wrong at my location. Relative altitude measurement is fine, and makes complete sense with the reset function. The altitude from GPS appears to work well, not sure if Apple look up the height from the latitude longitude from the GPS, or if they use the GPS height measurement directly. For my location it aligns well with the OS Map height contours. Incidentally the iPad Air 2 Wifi only model I am using has no built in GPS but obtains the location from my iPhone on the same Wifi network I believe, clever stuff. A pressure trend indicator is the most useful thing for a barometer, as this indicates the weather situation more than most things. The final thing is the scale of pressures on the dial, this is far too large. 930mB to 1070mB would have been enough.
