About 헬로루디, 내 손안의 영어 놀이터

Hello Rudy, an English playground in your hand that you want to go to again and again!

Have fun learning English at the English playground for 40 minutes a day!


100% English environment to learn while having fun
Everything children encounter at Hello Rudy is in English.
40 minutes in a 100% English environment where they see English, listen to English, and speak English will provide children with an enjoyable experience of English.

Various story-based speaking experiences
Rather than learning to listen to and read given sentences, children are immersed in interesting stories and have conversations. Even children who can think for themselves and communicate in single words at first will eventually be able to speak in sentences.

The fun of growing your own character & space
As you continue learning Hello Ludi, you can decorate your character with items obtained as rewards, and further develop it by obtaining friends and items that can help you grow LUDI-9, the space where learning takes place. This allows children to gain strong motivation for learning, enabling continuous learning.
