Is there a way to access the raw data of the Barometric Altimeter? I have seen it when looking at Blood Oxygen data and was wondering if there was a way to just read the data or do I have to do the Blood Oxygen to be able to see the reading?
Apple Watch Series 7
In theory, yes. But it is a developer API. You'll have to write an app. Here is the documentation: Apple Developer Documentation
All of the above. To quote the Apple Documentation:
Apple Watch Series 3, Apple Watch Series 4, and Apple Watch Series 5 also have a built-in barometric altimeter to get more accurate elevation gain/descent information. The always-on altimeter in Apple Watch SE, Apple Watch Series 6, and Apple Watch Series 7 is even more accurate, showing your current elevation in real time.
Okay, is there really a Barometric Altimeter in the watch or it is getting the readings from the GPS data? What is giving the readings a true Altimeter or GPS?
