I don’t use any third party apps on my watch except AutoSleep to catch sleep outside of my sleep hours, and even then I don’t actually use the app on my watch, it just runs in the background.

The default weather and fitness apps are what I use.

The fact that they got all the tech news outlets touting this as a “feature” is a hilarious display of apples marketing push. It’s not even a feature. It’s a sidenote.

I’d buy it for $400 if interested

I like both the Apple Watch and Fitbit. The things I like about the Fitbit are

1. the battery life (about a week with the Charge 6, or 10 days with the Inspire 3),

2. the sleep tracking (fully automatic sleep tracking without having to sleep within scheduled sleep hours or a sleep mode enabled like with Apple and Garmin),

3. and the simplicity of having all my data and Fitbit info in one app (with Apple, I have 4 apps for it: Apple health, fitness app, the Watch app, and a third party app AutoSleep.

If you are okay with foregoing the idea of sleep tracking with the watch, you can charge overnight. The SE is probably the best value smartwatch by Apple or any other company. If you do want Fitbit in a less than $350 ish device, I’d say fitbits do an amazing job with that (better than Apple and Garmin) while doing some other things well too, though they aren’t really smart watches (more like fitness trackers).
