Amazon today introduced Kindle FreeTime Unlimited, bringing togetherall of the types of content for kids and parents - books, games, educational apps, movies and TV shows - into a single service for kids ages 3-8.

For a monthly price of just $2.99 per child or $6.99 for the whole family, Prime members get unlimited access to kids titles. Those who are not yet Prime members can sign up for FreeTime Unlimited for a monthly price of $4.99 per child or $9.99 per family. FreeTime Unlimited will be available on the new Kindle Fire, Kindle Fire HD and Kindle Fire HD 8.9" as part of a free, over-the-air software update that will be automatically delivered in the coming weeks.

Kindle FreeTime Unlimited is an optional extension to Kindle FreeTime, a free feature on the new Kindle Fire family, which offers parents new tools like Time Limits, which helps parents manage their kids' screen time. FreeTime Unlimited is designed to make FreeTime even better for parents and kids: when a parent signs up for FreeTime Unlimited, titles automatically appear in FreeTime, sorted by their kids' age and gender, alongside the titles parents have already approved from their own collection of content. Kids can follow their own imaginations across books, games, educational apps, movies and TV shows without being dependent on help from their parents. Parents can feel comfortable handing off their Kindle Fire to their kids, knowing that all of the content is age-appropriate.

Amazon is launching the service as competition heats up in the tablet market among Apple, Barnes & Noble, Microsoft and Samsung.
