Leren Lezen voor groep 2 en 3 is an educational app developed by Klassewerk. It is designed to help young children in grades 2 and 3 learn to read through engaging stories featuring characters like Roos, Pim, Fem, and Siem. The app offers both self-reading and read-aloud options, making it suitable for children at different reading levels.

To make reading easier for young learners, the app includes a helpful "meeleeskaartje" (read-along card) and word cards for practicing individual words. Each book in the app also features a fun game that allows children to practice the key words from the story in an interactive and accessible way.

The app comes with one book included, but additional books can be purchased within the app. Some of the available titles include "Roos en de Kip," "Roos en het Voer," "Roos en het Schaap," "Roos en de Koe," "Les in Huis," "Pim en de Voetbal," "Fem wint Vis," and "Fem naar Zee."
