7netブックリーダー is an Android application developed by SEVEN i HLDGS.Co.Ltd. This free app is designed specifically for customers of SEVEN i HLDGS.Co.Ltd's internet shopping service, "オムニ7" and "セブンネットショッピング," allowing them to access and read e-books that they have purchased and downloaded from these platforms.

The main features of 7netブックリーダー include a viewer function that allows users to read their purchased e-books directly within the app. It also offers a convenient bookshelf function that automatically organizes and sorts e-books from the same series. Additionally, users can easily bookmark their progress and resume reading from where they left off using the app's bookmark function.

For customers who have been using the previous "オムニ7リーダー" app, please note that the services have now been migrated to 7netブックリーダー. With this new app, users can continue to read and re-download EPUB format e-books that they have purchased from SEVEN i HLDGS.Co.Ltd. However, it is important to note that other file formats such as XMDF and トッドブック are no longer supported.
