Does Apple Watch have an equivalent to Fitbit’s smart wake feature?

Hi, I have an Apple Watch Series 7, and I was wondering if there was an equivalent to Fitbit’s smart wake feature. It is basically a feature that allegedly tracks your breathing patterns and your sleep cycle to determine the best time to wake you up, up to 30 minutes before your alarm is set to go off. I was wondering if this is something the Apple Watch has natively, or is there an app needed?

Thanks in advance,
