I think you're saying your Garmin Venu works with your iphone but no Apple Watch will work with your iphone. That isn't true. So what did you mean to say?

I'm under the impression that an Apple Watch can capture heart rate and acceleration and other metrics. With acceleration, it can infer the types of motion I'm making, i.e. lifting weights, climbing stairs, cycling.

Again, please show where I'm wrong.

I'm strongly inclined not to get cellular in my watch. I'm under the impression that to do that, I would have to add a line and pay the cost of a line as if it were a line with a phone number. Correct me if I'm wrong. I also don't have cellular in my tablet for that reason. My carrier is AT&T.

I guess the Garmin Venu is discontinued because on Amazon, it is available only as renewed. And it got me looking at Garmin watches. The Garmin vivoactive 4S is particularly handsome. I'm reluctantly accepting the bulk of these things, and this model is less bulky. Also, the long service on a single charge is a big plus.

My current watch is a Seiko without even a second hand. It's very light and thin, and I use a leather band. Getting used to the bulk and weight will be something, and so will the sweatiness of most of the bands available. Maybe I can later get a leather band.
