Sticky notes is a pretty useful application which allows you to take quick notes. Windows 10 by default has a sticky notes application but with limited features. If you want a bit more advanced colored sticky note app for Windows, you should try Yellowpile. The application is quite different from the standard sticky notes and it allows you to change the color of the note, the font, and color of the text.
Once installed, you can add stick notes to your desktop and change the colors to suit your needs.
Not only you can change the color, but also the font color and font of the notes. When you create a new note, you can inherit the properties of the older sticky notes. There is an inbuilt scheduler available in the sticky notes, which allows you to create reminders in different modes. It can one-time (no repeat), on specified days of the week, or on specified days of the month. You can also get notifications in the form of note shake (animation), a pop-up message in the tray, and an audio message.
The app also comes with hotkeys to manage your notes. In case you want to import or export notes to another PC, it includes that as well. The app also features a recycle bin for past notes.
Yellowpile is a useful free sticky notes application with customization options. It is available free of cost and you can download it from the link below.
