Welcome to the Webroot Community,
Your iOS device will not show up under mobile security tab in your online account area. This is because that tab is reserved for the mobile anti-virus portion of the account, which currently only exists on Android devices. The iOS apps are not anti-virus applications. For a breakdown of backup utility, SecureSync, click here. And here is some more on SecureWeb, our secure browser.
Hope this helps?
