Firstly, this app is exactly what I've been looking for to help me track barometric pressure, notice past trends as they correlate to my migraines, and get alerts for the future so I can hopefully prevent migraines before they start. There is an incredibly reasonable one time fee, which is SO refreshing to see in an app these days, which I was more than happy to pay for. Secondly, I had some minor difficulty figuring something out, so I contacted the developers, who replied WITHIN MINUTES with a kind, detailed, helpful response, that immediately fixed my issue. I don't think I've ever written a review for an app before, but between the nonpredatory, easy-to-use app interface and the clear dedication and care the creators have for their app and its users, I just had to sing their praises here for a bit. Please, if for any reason you're considering this app, especially the pro version, BUY IT and support these lovely people!!

It works fine, but is spare on features. I’ve tried a few barometer/altimeter apps, but I always end up comparing them to Bar-o-meter, which I’ve used the longest. I like that Bar-o-meter, in addition to just showing the pressure reading from the internal pressure sensor, also shows the GPS altitude, an indication of the current relative GPS accuracy, the sea level pressure from online weather maps, and the predicted altitude from the difference between the measured pressure and the sea level pressure. Unfortunately, its reading of the internal sensor stopped working when I got my 16e. It would be nice to have another app with similar functionality, but I get that you’re aiming for this one to be fully offline. One suggestion would be a self-adjusting vertical scale for the pressure trend graph so that you can see finer changes. You also have a typo in “deteriorated”. It might be nice for the notification threshold to be user-selectable, too. Finally, I think $10 for the pro version is too much considering how much I will be using the app. It’ll mostly just be interesting during plane flights.

This is a perfect app. First it’s pay once not a subscription and not expensive. Second it does one three things I need without other distracting/annoying extras: 1 record the barometric pressure, 2 warn me of sudden changes up or down and 3 it lets me export the data so I can overlay it against my health or other data. Oh! And it has widgets!! I wish more developers would do single need apps.

*Updated*Experience was disappointing for me. I was glad to discover an “offline” barometric pressure access and altitude app and for free at that, through the promotion (that’s always a nice and yet often under appreciated gesture and imo a smart way to get the word out about your work). However, after onboarding the app blurred out data readings with a “motion data access needed” screen but with no explanation or direction to resolve it (iOS 18.5, iPhone 11). After time spent exploring settings options (trying this and that to enable it) in vain, I gave up and deleted it in disappointment. Further still, I noted that the app description in store wants access to your financial data, something that I haven’t seen too often in apps that I explore or use, prioritizing security and privacy over brand and developer where possible. Transparency on what data you are in fact surrendering and to whom it is given is a legitimate consideration. This reviewer tends to be suspicious when apps go free, have rushed or incomplete menus or onboarding, but want financials. In this case, it was asserted that only Apple has access to that data- probably so… so don’t let me spoil the barrel. Having said that, offline functionality is an enticing attraction but the breakdown for me came in the lack of clarity as to enabling the access the app needs to function. I still don’t have that info and as such I cannot rate the app’s merit or efforts sufficiently or objectively. As they are a two man developer team, I can respect the effort but if I can’t use it yet..
