Heart Analyzer App Gains Blood Oxygen Complication for Apple Watch Series 6

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.

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.”
