I'm sure there is a lot more.
(Also all the people losing weight)
But ... like I said, everyone has their own needs. And if you don't want all the smart crap, it's a pretty expensive heartbeat monitor.
[1] Or it crashes, or randomly starts draining its battery insanely faster because Google decided to force feed it an update or due to other reasons I can't fathom... but that's another story.
I don't want to baby multiple devices, one main work tool is fine to manage battery on a daily basis for instance AirPods charge roughly once a week or less depending on usage pattern. There's plenty of tech that balances battery and powerdraw appropriately. I find apple watch misses this mark unless a lot of functions are turned off.
I bought it for her primarily for the hypnograms.
I wanted something a bit smaller, to fit under the shirt cuff, so got the Mi Band 3 ($50) which lasts about 10 days (probably 20 days if you don't allow it to display notifications and set a higher HR interval).
The Mi app is pretty bad, which forces you to buy an extra app (for me, Notify & Fitness, for Google Fit sync).
On iOS, I use AmazTools [1] to sync the heart rate data to the Health app.

Some Garmin and Fitbit models have good battery life — often about a week.
Aneceotally, because the watch isn't really water resistant (not least because the bands bubble if they get wet often), I have had it run out twice in that time and both times I was on holiday somewhere with no power. Because you are unlikely to actually wear it in the shower, just leave the charger permanently in your bathroom and get in the habit of taking it off and putting it on the charger when you shower. Even if you forget for one or two days it will almost always be sufficiently charged.
The Garmin Forerunner 645 Music covers what I need short of the app support. The Nike Apple Watch Series 3 looks very tempting but I really don't like the aesthetic and I feel like it's just perpetuating the problem of being too online all the time. Though it's a far more feature rich device for less than the 645.
I'm thinking I'll sit back and wait for broader app support.
“Closing the rings” which means completing 100% of the move, stand and exercise targets adds a competitive element to fitness which has worked well for many users.
