The Pen tool is undoubtedly Adobe Illustrator's most powerful tool. It enables the artist to construct shapes using freeform curves, and most curves observed in the "real world" may be recreated using the Pen tool with practise and competence. Unlike the Paintbrush and Pencil tools, it does not draw wherever you drag.
Redraw and Sketch with Pen tool are two different applications that help designers to create vector drawings.
The Redraw app is a vector drawing application for macOS. It offers a variety of features such as live-updating vector shapes, a library of shapes and symbols, and more.
The Sketch with Pen tool is an iOS app that allows designers to draw vector graphics on their iPhone or iPad. The app has many drawing tools, symbols, and brushes to choose from.
Both Sketch and Redraw have their own strengths and weaknesses. Sketch is a vector-based design tool which is easy to use, yet has limited features. On the other hand, Redraw is a simple sketching tool that lacks some advanced features such as exporting to different formats or adding layers but it's very intuitive and easy to use.
The most notable feature of the Pen tool is that you can use it without having to worry about creating anchor points or handles. It also has a built-in ruler for creating straight lines and an easy way to adjust curves and lines.
