This was released in the UK last week and I think it's a great idea for those children with tablets, filtering out any unwanted content. The only issue with it seems to be the fact there are still adverts between videos, but Google state these are all checked to be suitable for family viewing.

The official YouTube Kids app is designed for curious little minds. This is a delightfully simple (and free!) app, where kids can discover videos, channels and playlists they love.

We work hard to offer a safer YouTube experience, but no automated system is perfect. If you ever find a video you’re concerned about, please flag it. This helps make YouTube Kids better for everyone. For more important notes about the app, please see below.

The app also removes social features like comments and the ability to upload videos; has a built-in timer to limit how long children can use it; and blocks inappropriate search terms including “sex”.

“We only show ads that are approved as family-friendly - for example, we don’t show any food and beverage ads - and all ads undergo a rigorous review process for compliance with our policies,” a YouTube spokesperson told the Guardian.

“All ads are clearly labeled and include ad intros. Ads don’t include any click-throughs to websites or product purchase flows.”
