Don't think I'll be trying it.
Their web site seems to be a ghost town. The app was last updated in August. And their web site and user guide don't really say how it works or why they're so unclear about the security settings, etc.
And it's free with no obvious indication of how they plan to make money. That means the users aren't the customers, they're the product.
Maybe I'll change my mind when I get a newer Android device, but ...
Thanks for the pointers and the information. It's been educational for me.
Cheers,
Scott.
