The Apple Watch is very useful. That’s why people keep buying it.
It’s nice to get notifications on your wrist if you don’t have your phone out 100% of the time. The alarms are silent and dead simple to set, and it can function as your wake up alarm in the morning, and sync with your phone as a backup alarm. It lets you unlock your phone while wearing a mask. It lets you pay for things instantly without taking your phone or wallet out.
If you are someone who exercises, the utility goes up even more. It’s great to control your podcast or music while out walking or running without digging around in your phone. It’s perfect for tracking your workouts, because it’s always on your arm and it tracks your heart rate.
I agree that the EKG & O2 level features are pretty much a gimmick. But the watch generally is an exceptional piece of technology.
