Do I need a separate license for my smart phone and if so how much does it cost.

Hello den07sid,
 
Welcome to the Webroot Community.
 
If you have Webroot Anywhere Internet Security Plus, its good for 3 seats. You can use your keycode license for your smart phone..I use Webroot on my Android as well.
 
Make sure to check as to which version you are entitled to/can use on your Android .Please see the contents of this KB Article for guidance on this.
 
Then please follow below if you have this Webroot version:
