If you’re interested in sleep trackers, https://youtube.com/@TheQuantifiedScientist has a decent YT channel explaining sleep trackers and their effectiveness. I swear by my Forerunner 45 for it being a great watch for the price but I do believe, the Apple Watch Ultra was the top sleep tracker when it came out from his tests.

I’ve been a staunch apple user since the original iPod touch and one day with my Forerunner 45 was enough to make me never pick up another Apple Watch again without some type of redesign. The out of the box experience for me personally was leaps and bounds better to get me up and moving. Suggested it to my wife who swore she’d never run unless she was being chased and now she’s running more than she ever had and ENJOYS running now.
