Heart Rate Monitor

Hello mcbsf,

Thanks for posting in the Apple Support Communities.

We understand you're not wanting to use Heart Rate with your Apple Watch, right?

If we have that correct, let's open the Watch app on your paired iPhone, then tap Privacy. From here, locate Heart Rate in the list to disable the feature. We were able to locate these step in the following resource that covers getting accurate measurements with your Apple Watch, so feel free to check that out if you'd like: Get the most accurate measurements using your Apple Watch - Apple Support

If you turn off Heart Rate in Privacy settings, you also won't get a heart rate measurement. To see if Heart Rate is off or on, open the Watch app on your iPhone, then tap Privacy. 

We hope this is able to help.

Have a great day!
