Norton by Symantec has released a free app Norton Safety Minder: Mobile Edition that keeps an eye on kids’ smartphone activities.  

The tools in this application, which is part of Norton Online Family, teach kids safe and age-appropriate digital habits on their mobile devices.

The parents use their Norton Online Family account to set filter settings to monitor and block harmful sites.  They can also apply this on the child's PC. The service tracks up to seven days of content for free.

The parents can use the same account to manage the “House Rules” on more than a dozen devices at the onlinefamily.norton.com website at no charge.
