Wacom today announced the Bamboo Sketch, a new precision stylus for drawing and sketching on both iPad and iPhone devices through a Bluetooth connection. The company said that the stylus mimics a traditional pen-and-paper writing and drawing experience thanks to two customizable shortcut buttons and two interchangeable pen nibs, in both soft and firm.
The Bamboo Sketch can be used within apps like Bamboo Paper, ArtRage, Autodesk SketchBook, Concepts, and MediaBang Paint, and when it’s in use the stylus boasts 2,048 levels of pressure sensitivity.
The pressure sensitivity is in the stylus so this will work on older tablets too. Actually no reason why it could not work on Android either but it would need app support.
