Polar has a lot of shyt going on, csn you point to whichever product you're using?
I have a few polar watches. Polar is a fitness company so I use it to track my workouts, and I put in a fitness goal like to be able to run 10k in 45mins in 200 days and it automatically generated a workout program that's tailored to my body and stats, tells me when I'm working too hard, or not working hard enough, tracks sleep and recovery, has GPS to track my runs and such, can measure vo² max and heart rate.
Oura does a lot more, but once I've bought the polar watch, I have access to all these features...I don't have to subscribe for monthly access.
That's the main thing, I don't like the access being behind a paywall especially when you pay $279 marked down from $350. I guess if it stops working or you stop you still have a cool looking ring and $70 a year is affordable. I just don't like it.
