## What is Barometer & Altimeter Pro?

This app uses the barometric pressure sensor built into all newer iPhones and iPads and features a Barometer for weather, an Altimeter for outdoor activities and a History feature with CSV export to track air pressure.

No ads, no internet connection, no trackers! Runs on your device only!

Keep an eye on the barometric pressure and be your own weather forecast! This little app uses only GPS (optional) and the barometric pressure sensor to calculate the barometric pressure used in weather forecasts. iPhones and iPads have a barometric pressure sensor built in so this app works completely without internet. The handy marker helps you keep track of changes in the barometric pressure and lets you predict weather changes! Air pressure and its change over time is a very good indicator for weather!

The History allows you to store pressure values over time and compare. With a single click you can export it all as a CSV file.

The Altimeter helps you track your altitude changes based on the change of pressure. Just set your reference pressure and altitude in order to use the Altimeter for checking how high up the mountain you have climbed (works for other activities too). Most users will simply rely on GPS for altitude information but GPS does use a good bit of energy, so this app does not rely on GPS for the Altimeter and can help you gain an estimate, even with GPS disabled (by default the App does use GPS for calibration, configurable).

Features
- Barometer for weather.
- Altimeter for height estimations.
- No internet connection required since the sensor is built into iPhones and iPads.

### 1/5 — Update has destroyed this app!

*2024-05-07*

I’ve had and used this app for years! I have chronic migraines and one of my biggest triggers is change in barometric pressure. There are other ways to predict the changes, but with this app I had an amazing graph that I could set at intervals from 24 hrs to 30 days to correlate when I first noticed a migraine coming on, when I had a particularly severe migraine, when I had a migraine that lasted more than 24 hours, etc. Being able to look back at these graphs and put them together with other variables that I know affect my migraines has helped me so much with my migraine care. 
With the update, however, the graphing feature has disappeared. In fact, the app only marks the pressure if you actually go into the app and mark it. It’s useless.

### 1/5 — Updated Not Anymore….Helps verify what I’m feeling

*2024-05-01*

This app used to be so helpful in understanding and explaining every change in my daily migraine pain level. The changes made to the app a couple of weeks ago removed every single thing that I found most helpful. There’s no graph that shows the small to large changes that take place over a span of time. It was a relief whenever the app’s graph showed a change when the pain level changed because it meant not having to review every other aspect of daily living that might have caused it. I can no longer choose the number of hours to review during or after prolonged episodes. I tried to continue using it but cannot find anything it provides that’s helpful. 

I started using this after trying others normally suggested for people with migraines affected by barometric pressure changes. I don’t comprehend all the technical explanations but I can now use this app to verify what the pain has told me. I don’t have the “extras” but plan to try them when it’s easier to read and comprehend through pain and nausea. I spent years trying to find and understand my triggers and thought barometric was one but needed an app showing it as numbers and on a graph to see how small the changes can be that make my migraine spin out of control. Verifying it gives me the knowledge to take actions that can help keep it from being as debilitating. Thank you!

### 4/5 — Please help.

*2024-04-11*

I’ve been using your app for years!
It helped me decide if I needed to take migraine medication or not, it was so useful. 
Unfortunately in the new update there is no “line” that shows the tiny pressure changes. That was the part that helped me, I also used it to show my doctor. It was a visual aid. 
Now, I don’t have that.  This new version does not have that quick visual reference and I don’t think I will be able to use it. To be honest the numbers don’t really help me. Is there any way you could put that back? 🙏

### 2/5 — Every feature I loved is gone…

*2024-04-09*

Talk about devastated. I’ve never even left a review before this moment. 

I’ve been using this app probably since it was released to track my pressure drop migraines. I could see when drops occurred on the graph and if the times lined up with symptoms. I could quickly glance at the color-coded dial and know if I was at risk. I could check the pressure at a glance with the widget. I used this app every single day and recommend it to every migraine sufferer as I know as a much needed tool!

I noticed today that the widget was just gone. Couldn’t add it back either. Opened the app to find it completely redesigned and every feature I used is now gone as well. The graph is gone entirely. The color-coded dial is gone. The widget is no more. It’s completely barebones. Sure, it looks pretty, but it’s lost all usefulness and I had to find a new app. Beyond bummed.

### 2/5 — Was great, give me back my 30-day trend graph

*2024-04-08*

I’ve really liked this app up until now, but the feature I liked most is just gone.
The Trends page used to give several options between 6 hours and 30 days and it was fascinating to compare the pressure over that length of time. Now the Trend is just the time and pressure, no graph.
Also the app says I’m at -86 feet elevation when I’m right at sea level or up to about 10 feet above, and wants access to my fitness app. 
Might delete and find an app that has a Trends graph, I don’t like this at all any more.

### 3/5 — App has been downgraded since Update

*2024-04-06*

I used to love this app and I used it frequently to check the barometric pressure since it affects my arthritis. However, since the latest update going to analog from the digital, I have lost interest in using it and am actively looking for a suitable replacement. I can deal with the analog barometer. However, I really miss the graphic display of the history including the ability to adjust for number of days. It was probably a 4.8 star rating before the major downgrade of your recent update.

### 1/5 — What happened to the app after the Apple update April 6, 2024?!

*2024-04-06*

Several years ago, I paid to upgrade the app, so I could change the face between several different options, plus, I was able to show 2 different pressure units on the face at the same time. Those are all gone now! I do NOT like the way app looks now. It’s extremely sparse and basic looking. There’s no longer a chart showing what the barometer has done the last 6 hours to 30 days. It is totally off and when I put in my altitude, it’s really off. I don’t know what is going on, but please, bring back the old version. Also, I’d like a refund of my money, since I’m no longer getting what I paid for. This version is no way, shape, or form, a better version of the old!

### 1/5 — The New Release is AWFUL

*2024-04-01*

The new release removes precision and also deletes various appearances of the barometer, leaving the only option a bland and sketchy looking thing. I used to love this app. and the so-called “trend“ no longer shows a trend it makes you click each time you want to store a point. Before it made a very nice graph that showed over 30 days or less the ups and downs of atmospheric pressure. This “upgrade“ is a horrible change. I’ve deleted the app from my phone and my iPad and I am totally disgusted that I bothered to upgrade it because it ruined what I really used to like. Great job, not!

### 1/5 — Great to bad :-(

*2024-03-30*

Used this daily for years… until update! All the features I like are now gone. Please roll back this update or adjust it. Honestly it’s like this version was created by someone else it is so different. It has been so helpful until now, I sincerely hope that it will be changed so it can again be my beloved app and I can edit this review.

- Watch app is now gone, my favorite part

- Please add option to have dark screen only. White is rather jarring, too bright, for migraine people and others with sensory sensitivity.

- Trends screen in former version was great, loved being able to track changes with options from 12hrs to 30days and the slider bar to see specifics. Now you’re asking me to look at a list of numbers, and other info, and do math. Really?!

- Widget gone. I used widget on iPad and on phone used the old style widgets you can add only to the “today” screen. Both types are gone.

### 5/5 — Very glad this app exists

*2023-06-06*

I’m grateful that this developer has put so much work into an app whose key features are 100% free. I was looking for an app that gave me the output of my phone’s internal barometer, and that’s exactly what it does. And you can even set the little red marker to track changes! And no ads, not even in the free version! Thanks, developer.

To the people complaining about the tracking not working while the phone is locked: it’s obviously an iOS limitation.
