The BBC has launched its free Cbeebies Playtime for Windows Phone 8. Already available on iPhone, iPod touch, iPad, Android and Kindle Fire devices since August, the app offers a number of games and activities for pre-school children, all based around some of the channel’s favourite characters and licences.

There are sections dedicated to Alphablocks, Octonauts, Tree Fu Tom and Something Special starring Mr Tumble. Up to four children can have profiles so their own progress is saved and adults get their own section so they can see what their kids are to encounter without having to log in themselves.

The Beeb explains that it was able to make the app truly cross-platform thanks to developing it using Unity, the technology that makes conversion for different systems easy.

Patrick Healy, the head of Product for Children at BBC Future Media, explained that because the department has recently switched to Unity there is now more potential for future cross-platform releases. "By using the single codebase workflow, we can add further games content and features to these platforms as needed, without the overhead of repeating major work for each platform," he said.

"This allows us to efficiently maintain as synchronised an approach as possible to the releases in each app store."

Cbeebies Playtime is now available to download for free from the Windows Phone Store.
