Parents need to know that the content in BrainPOP Featured Movie is produced by a well-respected educational organization. The content changes daily (though everything is archived, so kids don't feel pressured to use the app every day). Each day, there is a new animated documentary, and it could be on just about any topic you can think of. Film topics have included the planet Mars, dogs, asthma, blogs, and Mexican artist Frida Kahlo. These films and the information within are geared toward older elementary school kids. While there shouldn't be anything offensive or scary for younger kids, the movies – and the quizzes that follow them – may be over the heads of kids younger than 8.
