[Discuss] how to build a smart watch for kids

[Tom Luo]

Hi, all,

I know it is a big topic, but I want to know more about this.
I want to build a GPS smart watch for kids, like these two watches in
amazon:

I want to know which operating system it uses in the smart phone. Is it
android?
It looks like it comes with cell phone apps, so I guess I also need to
build a server for it.
I don't have time to go to Shenzhen right now. So, I just want to ask
anyone who has any idea about how to build it.


Thanks a lot and happy new year to all!


Best,

Tom
