The Livescribe 3 smartpen and Livescribe+ app is not currently compatible with Android. An app for certain Android devices is under development and is now expected to be released in early 2015.
Our decision to launch on iOS devices was based on the fact that Apple devices have supported Bluetooth® Smart technology since the release of the iPhone 4S. Android support forBluetooth Smart technology was only just announced with Android v4.3 (Jelly Bean), which was released in the summer of 2013 and is only available on a handful of Android smartphones as of November 1, 2013.
The reason we developed a Bluetooth Smart device is because it is the right and best connection protocol for use with a smartpen. The bandwidth requirements, ease of pairing and enormous battery benefits make it the right choice. It is the same technology being adopted by a variety of other connected devices including heart rate monitors, fitness bands (FitBit, Nike Fuelband) and others.
