A subscription can be used across any compatible device (including Chromebooks), giving kids access to over 10,000 ebooks, videos, Audible books, games and educational apps.

That content is all curated, including the videos which are available via the kid-safe web browser, and divided up into various age-appropriate categories.

Amazon has also made changes to the app’s home screen on Fire tablets, with a brand new one for kids aged 8-12. Previously the home screen was aimed at younger children, but new design is more customisable and should appeal more to older kids up to 12. This should roll out as a software update shortly.

The company has also added more music and videos in the ‘Older Kids’ category which previously didn’t offer as much as for younger ages.

Amazon says it will also add music stations and playlists from Fun Kids to the home screen of Kids Edition Fire tablets.

You don’t have to be an Amazon Prime member to use Kids+ but you do get a discount. And, it has to be said, there isn't a great deal of point in installing the app on iOS or Android unless you plan to take out a subscription.
