There is an open source project providing similar functionality
called Mnemosyne that runs on Linux, Mac OSX and Windows.
Its home page is here: http://www.mnemosyne-proj.org/index.php
It uses a system of spaced repetitions to significantly increase retention and memory. It's been around a long time and has been refined over many years. The creator was featured in Wired not long ago..

Unfortunately it's windows only.
