I recently came across this website that I thought was very helpful in finding good apps, movies and websites for families with children. Here is their website and mission statement. You may want to check it out.
"Common Sense Media is dedicated to improving the lives of kids and families by providing the trustworthy information, education, and independent voice they need to thrive in a world of media and technology.
We exist because our nation's children spend more time with media and digital activities than they do with their families or in school, which profoundly impacts their social, emotional, and physical development . As a non-partisan, not-for-profit organization, we provide trustworthy information and tools, as well as an independent forum, so that families can have a choice and a voice about the media they consume."
