I mean if you don’t use the health app you’ve eliminated like 90% of what the watch is for. The entire premise is a wearable biometric sensor that also functions as a direct link to your phone.

I have an ultra that I use for a ton of stuff. I originally got an SE for the better sleep tracking, but that turned into using it for workouts at which point I got a series 8. When I got into longer distance cycling (75-100 miles) the battery on that didn’t last long enough so I upped to the ultra.
