Nope, I don’t have one. /r/Garmin would be a good resource. They get into discussions about chest straps.

Chest strap is always recommended if you want high accuracy.

Tap it and see what happens?

I would suggest a Garmin Vivosmart band for him, or a life alert system. https://www.garmin.com/en-US/p/782585

You are not going to get blood pressure from a watch, but you can buy him a blood pressure cuff that reports to you.

What is it you need most? Would a daily phone call be the better option? I know a few people who call their parent every day to check in.

Maybe that sentence needs a comma. “addresses issue, making the battery drain faster for some users”…

You can check for the battery bug. Just-me-for-now posted:

On your iPhone, open Watch app. Click on General and scroll down to bottom to diagnostic logs. Click. If there are problems with your watch, this is where the information is written that developers want to access. This comes from years of being a tech analyst. lol. Open one. You can see at the top of the log that it is on 10.1 and the build should be (21S67). At the end of the first bracket of information you will see bug_type and 298. This seems to be the same bug that was in 10.1 beta two that was patched in 10.1 beta three.

It’s part of the whole 10.1 problem. I would just wait to update after apple fixes it.
