The special feature of the Apple Pencil of the second generation is that it has advanced sensors in its pencil tip, which turn it into a very precise input device. The sensors determine the position, tilt and pressure, and the stylus responds accordingly to enable pixel-perfect, fast and smooth writing or drawing. Additionally, two frequently used tools can be preset and then selected by double-tapping on the Apple Pencil 2, switching back and forth. The pencil can be magnetically attached to the iPad Pro and charged wirelessly.
