ONE PIECE 公式漫画アプリ is an official portal app that allows you to read the full-color version of ONE PIECE, the popular manga series, every day. You can read at least one episode per day by using "logs," which accumulate every day at 1:00 pm.

There are three ways to acquire logs: free logs, purchase logs, and bonus logs. Free logs are given every day at 1:00 pm, but there is a limit of 245 logs, and they cannot be used for purchasing e-books. Purchase logs can be acquired by buying e-books, and they can be used for purchasing e-books. Bonus logs can be acquired by completing mini-games or participating in limited-time events, and there is a limit of 2000 logs.

In addition to the manga, the app also provides the latest news about ONE PIECE. The app is compatible with iOS10 or later, but it may not be available on some devices or environments. iPad Pro is not recommended for use.
