The Livescribe 3 Smartpen is an extraordinary pen because whatever you write on paper is automatically copied onto the screen of your tablets or smartphones in real-time, as you write it. How does it work? It’s not magic, it’s Bluetooth. The Livescribe Smartpen picks up the motion of your scrawl on paper and transmits it wirelessly to the Livescribe app on your smartphone or tablet. The best part is that the app can record audio and sync it with the digital copy of your notes. All your notes and comments are now stored, tagged and searchable as data that you can send or share with others. Besides all this, you get to own an exquisite pen with a retractable tungsten-carbide ballpoint.
