교원 북플레이 is an Android app developed by 교원 that offers a variety of free content related to their educational books to subscribed members. With the help of the 교원스마트펜 and the 교원 북플레이 app, users can enhance their knowledge and enrich their reading experience.

Please note that the current version of 교원 북플레이 does not support Android 9.0 (Pie), but an update is planned in the future.

This app provides a convenient way for members to access additional educational resources and expand their learning beyond the traditional books offered by 교원. Whether you're a student or a lifelong learner, 교원 북플레이 can help you broaden your knowledge and enjoy a more interactive reading experience.
