With the Livescribe Echo 2 Smart Pen and Livescribe + mobile app simply write in the Livescribe notebook and watch it instantly appear on your tablet or smartphone. Your notes become infinitely more useful when they are tagged, organized, searchable, or even converted to text. Easily add recorded audio that's synced with your handwriting so you can relive important moments. Quickly share notes and ideas with friends, colleagues, and peers. Recording audio can be activated via the pen and the mobile app. The Livescribe Echo 2 Smart Pen also has a microphone and speaker built in, so recording audio can be done without the application being open. The recordings will be accessed through the application, though.
