I don't think you're correct.
1. There are more settings than the two you mention: Continuous or Off for the Heart Rate (HR). Samsung Health can be set to monitor HR every 10 minutes, not Continuous and not Off. My watch is on the 10 minute setting.
2. I have loaded several watch faces from different makers, and all of them only show a heart when the Samsung Health HR Complication is included on the watch face.
I've exchanged messages with one of the developers and he revealed that Samsung is not supplying necessary information to display the current heart rate. To check on what he was telling me, I loaded other watch faces and they failed to present the accurate HR information.
There are a few (very few) watch faces that do provide the HR information, but I believe they are developed by Samsung.
A major point behind going with Wear OS is so more apps and options, like watch faces, are available.
If you are satisfied with the relatively few Samsung developed watch faces, good for you, but I want better. I'm sure there are many more Watch4 customers who do also.
My Galaxy4 watch is less than a month old. And I checked and it has the latest software. I'm posting this because Samsung needs to recognize that they have not developed the Samsung Heart Rate Complexity properly for the Wear OS Samsung Galaxy4 watch. Surprising that they have to be told something so simple.
However, I have found a really good Complexity to replace Samsung Health on my Galaxy Watch4. It's called Cardiogram. Not only does it display the Heart Rate on the watch face - yes, the actual BPM number, not just a heart icon - it also tracks sleep, steps, and other health parameters. Unlike Samsung Health, it permits setting a variable for the number of minutes between measures - from 1 to 15 minutes - so it has more flexibility than off, constant, and 10 minute intervals to conserve the battery needed for HR measurements.
It has off and automatic measuring as well as the variable interval. I highly recommend it.
Thank you for your feedback. We are happy you found Cardiogram and it is working well for you.
