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. DotPen introduces a unique Active-Quill writing tip. Crafted from a durable thermoplastic, the Active-Quill tip has an extremely low coefficient of friction which glides effortlessly over glass displays with zero latency. This precision fine point tip feels remarkably like a real pen and provides stunning clarity of resolution for both drawing and writing. DotPen is made of precision CNC machined anodized aluminum alloy and a durable soft-touch rubber writing grip. Built to last and built for effortless writing and sketching.
