The infrared camera in the tip of the Livescribe 3 smartpen captures your handwriting, storing it on the built-in memory. When it's paired with your tablet or smartphone, all your notes are synced to the Livescribe+ mobile app. Livescribe 3 smartpen uses Bluetooth Smart technology to pair with compatible mobile devices to support over 14 hours of continuous use between charges. Pairing is also made much easier – just turn on the Livescribe 3 and accept the pairing request on your mobile device with a single tap. After that, your smartpen will pair automatically each time you launch the app.
The Livecribe 3 smartphone currently works with devices running iOS7 or newer; iPhone 4S or newer, iPad third generation or newer; iPad mini, iPod touch fifth generation or newer.
