簿記3級 倒して覚える勘定科目 is a free app for Android that helps you learn accounting in a fun and engaging way. Developed by 株式会社 Leone, this app is designed to help you efficiently memorize accounting concepts and principles.

The app is based on the idea that memorizing accounting can be as easy as remembering the names of 151 monsters in a game. The app turns accounting concepts into enemy characters that you need to defeat to memorize them. In the first stage, you learn whether an item belongs to "資産," "費用," "負債," "収益," or "純資産," and whether it belongs to the credit or debit side of the account. In the second stage and beyond, you learn which account an item belongs to and whether it is a debit or credit entry.

With 簿記3級 倒して覚える勘定科目, you can turn your memorization skills into a powerful tool for learning accounting.
