Handing your child a tablet with unlimited access to apps, games, and the internet at large is not a good idea. However, tablets can be great for kids if used with safeguards in place. That's what both Amazon Kids and Google Kids Space aim to provide, but they do it very differently.
Amazon Kids—not to be confused with Amazon Kids+—is a feature that lets you create child profiles on Amazon Fire tablets. It allows you to share selected content from your own library with your kids and set parental controls to limit screen time, filter age-appropriate content, and manage web browsing and content usage. Your kids access everything through a custom home screen, and it can be enabled on any Fire Tablet, not just those marketed as "Kids" models. Amazon Kids requires a child account to be added to your Amazon Household.
An optional $5 per month subscription service called Amazon Kids+ can be added to Amazon Kids accounts. It offers thousands of kid-friendly books, games, videos, music, apps, and Alexa Skills from brands like Disney, Nickelodeon, Marvel, Lego, Sesame Street, and PBS Kids.
Google Kids Space is a tablet experience with a custom home screen and library of quality content aimed at children under 9. It allows kids to customize their experience with unique avatars and receive content recommendations based on their interests, while parents can set boundaries with parental controls accessed through Family Link. Google Kids Space requires a Google Account for your child and a compatible Android device. It includes apps, games, books, and videos that have been approved by teachers and children’s education and media specialists.
Google Kids Space doesn't have an explicitly kid-friendly subscription service option like Amazon Kids+, but it does work with Google Play Pass. When you activate Play Pass for a Kids Space account, it unlocks additional premium content that doesn't have ads or in-app purchases.
