The pen is designed for drawing on paper, while the smart stylus is designed for writing or drawing on mobile devices like an iPad, iPad Pro, an Android tablet, or a Microsoft Surface tablet.

Less than $25.
An Internet connection isn’t required to use your Scribble and capture all the colors of your world, but to transfer your captured colors to a mobile device, you will need a Bluetooth connection.
