Tree Note is a free notepad app that helps you organize your thoughts like a mind map. It allows you to itemize and arrange your memos in a simple and effective manner. With its user-friendly interface, this app is perfect for anyone who wants to organize their ideas more efficiently than a traditional to-do list app.

One of the unique features of Tree Note is the ability to check the number of words on the edit screen, which is useful for drafting papers and novels. The app also allows you to create quizzes by writing questions in the 'title' and answers in the 'contents'. Moreover, it provides a display format of 2 rows and 2 columns, which is ideal for practicing 'The 7 Habits'.

However, it is important to note that the app may use usage information to improve ads and the app itself. The input data may also be lost, so it is recommended to save important information to another app. Overall, Tree Note is a great app for organizing your thoughts and ideas in a mind map format.
