Update: granule is no longer actively developed. The SourceForge project records its last update in August 2012.
granule is a flashcard program that implements the Leitner cardfile methodology for learning new words. Leitner’s system consists of a cardboard box separated into a number of compartments. These are filled with flashcards and the flashcards are moved from one compartment to another, according to the current level of knowledge. When a flashcard is answered correctly it is promoted to the next compartment. When a flashcard is answered incorrectly it is demoted to the first compartment.
This software features both short-term and long-term memory training capabilities with scheduling.
It enables you to organize and use your flash cards effectively. Flash cards are used mostly by the students of the foreign languages to memorize the meaning and spelling of the new words. It can also be used to organize and study new material of any kind.
