JsekiTsumego

JsekiTsumego is a program that utilizes spaced repetition (the Leitner method) to help memorize life-and-death problems. It uses the "Status?" approach rather than requiring the user to find the correct move, which more closely approximates real-game scenarios that a player is likely to encounter.

    It is! JsekiTsumego is licensed under the GPLv2. The JAR file that you download contains all the source files required to compile JsekiTsumego. Simply unzip it with WinZip or any other utility that handles zip files (you may have to change the file extension to ".zip").
