Heart Analyzer today reached version 8.3, bringing some notable improvements to the popular heart health app including new complications and customizations.

Top of the list for Apple Watch Series 6 owners will be the new Blood Oxygen Saturation complication, which lets you track the SPO2 metric over the past week with a glance of your watch face.

There's also a new complication that shows the chart for today and yesterday's heart rate, and a new toggle in workouts that lets you view heart rate zones by percentages or time in zone.

Meanwhile, on the iPhone app, a new custom scaling feature lets you fix the minimum and maximum values on heart rate day charts for better day-to-day comparisons.

Following version 8's big update earlier this year, the developer has also introduced a new heart rate chart complication, ECG comparisons on the iPhone app, and iOS 14 widgets.

The app never transmits any data from the users ‌iPhone‌, and there are no third party analytics and no ads. Heart Analyzer is a free download for ‌‌iPhone‌‌ on the App Store, and users who wish to support development can unlock small options via in-app purchases. [Direct Link]

I've been using this app for awhile, it is a great free app.
Interesting. I’m pleasantly surprised this is free, but disappointed if some combination of Apple Watch and iOS apps doesn’t already do most of this this. (I have a S6 watch waiting for Xmas...)

It looks like it’s just a few $2 IAPs that are the revenue generator for the app. Or are there ads as well?
 
Glad to see this app getting attention. I purchased all of the IAPs; the data is fantastic.
The developer has been responsive to feedback as well.
The O2 measurement, like HR, will be much more valuable over a long time scale with large data sets. Heart Analyzer will enable that!
The effect of a few drinks, or consistent exercise, is easy to see in the data. Good motivator!

“Heart Monitor” is another good one - activates the higher-fidelity HR sensor without triggering a “workout.”
 
For me, I primarily see it charting the O2 level at night, and maybe one or two times during the day.

Is that how it is working for everyone else?

I presume it is because I often am moving around and so the O2 sensor can't get a good enough reading. At night though, it will get a lot.
 
I’m not saying this isn’t cool, but if you are not actively suspicious about a potential medical problem, there is absolutely no reason you need to track your blood oxygen saturation. I guess if you want to add it to our ever-growing list of constant monitoring-in-case-anything-ever-happens metrics it’s fun but super irrelevant unless you’re sick with a respiratory illness or airway problem. And if people are thinking COVID, you’ll likely have other symptoms well before your oxygen starts dropping below normal - that’s in the later stages most commonly.

But I ain’t no docta.

It seems to try every 30 minutes, and only keeps the successful readings.

Most days, I get 10-15 readings added to my data, which is enough for my pulmonologist to see trends, and I trigger it manually if I need to check (severe asthma here).
