The bottom line is that these watches (including but not limited to brands Gator, Tinitell, and Xplora) have NO security in their database and allow ANYONE to access ANY USER'S DATA without having to log in. This is a year after a Norwegian government report on this, and NOTHING HAS BEEN IMPROVED. This is perhaps the worst example of a saying I frequently roll out: security wasn't an afterthought, it wasn't thought of at all.
In short, if you think it's really cool to be able to know where your kid is at any given moment, realize that Joe Blow can do it, too. And the watch company simply doesn't give a damn.
My recommendation is to throw the damned things into the garbage to keep someone from accidentally using it in the future.
