The Apple Watch Series 10 is my current wearable of choice. I use it to track all the health data Apple can squeeze into a smartphone and all the workouts I do as part of my marathon training. I've reached a point in my life where I'm paying more attention to my well-being, which means I'll always have a wearable on me to help with that.
I've also started thinking about smart rings more and more in recent years. I thought Samsung's Galaxy Ring would work with the iPhone and wished Apple made a smart ring of its own.
