4ColorNote is a simple note-taking app that lets you organize notes using four colors: black, red, blue, and green.
Choose a color that matches the content of your note, save it, and quickly display only the notes you need by selecting a category at the top of the list. You can customize each color’s label to suit your needs, such as Work, Ideas, or Plans.
Main Features
• Organize notes using four colors: black, red, blue, and green
• Customize the label for each color
• Filter notes by color
• Search the text of your notes
There is no need for complicated folders or detailed organization. Simply divide your notes into four colors.
Quickly capture your thoughts and find the notes you need by color.
Examples
• Organize tasks by urgency and importance
Urgent and important → Red
Urgent but not important → Green
Not urgent but important → Blue
Neither urgent nor important → Black
• Track tasks by status: Not Started, In Progress, Waiting, and Done
Not Started → In Progress
Change the color from black to red to show that the task is now in progress.
