I had a baby in April, got my Apple Watch on my birthday in January. It determined that for two weeks after I had my baby, my average resting heart rate changed, and notified me. I was amazed because the rate of change began on my baby’s birthdate.

It’s also notified me that I’ve had a higher heart rate and asked if I was okay on two separate occasions. Once after getting my tetanus vaccine, when I was running a fever, and the other time was when I had Covid. It was my first symptom and I didn’t even know it until my watch notified me. Pretty cool technology, in my opinion!
