FNote is a free Android app developed by Notas Notepad that serves as a comprehensive folder notes app. As the name suggests, it allows users to create folders and sub-folders to organize their notes. The app doesn't limit the number of folders and sub-folders that can be created, making it a great choice for users who need a lot of organization in their notes.

One of the key features of FNote is the ability to password-protect individual notes. This makes it a secure app for users who need to store sensitive information. Additionally, users can add checkboxes in their notes and change the font color. FNote also supports landscape view, making it easier to type on a wider screen.

FNote comes with widgets that support notes and menu shortcut widgets. Users can also backup their notes on Google Drive. The app also supports optimized color themes, making it customizable to the user's preferences.
