You can attach a kid watch to your iphone plan. They get their own number and are part of your family management. It works really well.

At least one parent must have an iphone, though.

There is no watch specifically for kids, we just gave ours my wife's old one (I'm on Android, so ...)

Sounds a bit different than what Google is offering. Google’s look more like imoo. Which is just a standalone device made for kids. So kids can pair their devices and use the restricted set of images (emoji-like but more restricted) and features. Everything in the watch is made geared towards kids (like classroom mode, for instance). That Apple Watch thing seems like an after thought and it seems a lot more expensive. I’m assuming that the iPhone doesn’t need to be near the watch for the kid to use, right?

Right. The watch has LTE and does its thing independently.

It does have kid features like schooltime. It's not priced cheap for kids - cheapest new is almost $500. (Hence giving our kid a two or three year old, used one. :-)
