DotPen redefines drawing and writing on tablets and smartphones. DotPen actually feels and writes just like a pen, does not require special software, and works with any iOS, Android, and Windows touch interface device. At 143 mm long and 11.9mm in diameter, DotPen feels like a real pen and features a unique 1.9 mm Active-Quill tip producing amazing fluid pin-point writing accuracy. Powered by a single AAA battery (included), DotPen provides up to 12 hours of continuous latency-free drawing and writing. Powered by “MagicTouch” technology, DotPen does not rely on special pre-installed software or specific apps. With a touch of a button, DotPen instantly activates to work across any device using capacitive touch. DotPen works independently of special software or special settings in apps. So it virtually works with any app, including popular apps such as ZoomNotes, Evernote, Paper by FiftyThree, ProCreate, and many more. Many capacitive touch pens have cheap rubber tips that easily fall off and feel mushy and sluggish.
