Pixi - Was ist Fernkälte is an Android app developed by Carlsen Verlag that falls under the Education & Reference category and specifically, Books. The app is a fun and interactive way for kids to learn about the concept of district cooling and how it works. It is based on a Pixi story about Fernkälte commissioned by Wien Energie, and it has won the MOMMY AWARD in the category of Apps for Kids and was nominated for the AKEP (Best Performance in Electronic Publishing) AWARD.

The app offers a great reading and listening experience for kids, with amusing animations and sounds. It also includes a read-aloud text that can be turned on or off, a picture puzzle, a Pixi crafting tip, and an extra feature that allows children and adults to record their own story on a separate audio track. The story follows Ida and her friends as they visit the radio building on a hot summer day and learn about how district cooling works from Michael, a technician from Wien Energie.
