Seven months after making its debut in the US, YouTube's kid-friendly service is now available in Ireland along with Australia, Canada, New Zealand and the UK.
The app comes with a filtered selection of channels and videos that are appropriate for children.
Ability to upload videos or comment is also absent from the app, and there's a timer function built-in that allows parents to specify the amount of usage.
Google has mentioned that YouTube Kids has been downloaded over 10 million times since its debut, and that people have spent more time watching Wheels on the Bus than Psy's Gangnam Style.
The app will feature local channels, with the likes of Morph, Teletubbies, Wallace & Gromit and The Magic Roundabout accessible by users in Ireland and the UK.
