Apologies if this has been covered, but I did search and didn’t find any one comprehensive thread.
I’m looking to purchase a smartwatch that can track sleep phases, sp02, heartrate etc. I’m curious to get some input on other user’s experience with various models and also some ideas on what features/parameter tracking can be most useful to me for this.
I also would like to track my general fitness, but my most important criteria for purchase is sleep tracking. Thanks.
