Google today pushed out a significant update to its YouTube Kids mobile application, giving both kids and their parents new features to enjoy. For example, kids can create their own profiles each with a customized appearance. The app is more fine-tuned for children’s ages. Older kid will see more content on the home screens, while younger kids will be served less text. For parents, the app has a new setup process to help them select the content that’s most appropriate for their kids. Last, kids get their own passcodes to protect their profile so siblings can’t make unwanted changes. Google says the kid passcode can be overridden by adults. YouTube Kids is free to download.
