A vocabulary training app that builds upon the KVTML 2.0 file format. KVTML is a dictionary-like format commonly used by The KDE Education Project. It is compatible with Parley and WordQuiz (KWordQuiz). Vocab Drill can also open training files from Dropbox. Some features: multiple choice mode, flashcard mode, Dropbox sync, (some) stats, Leitner system, file entry browsing and search, plus lessons are supported too.
Vocab Drill is now open source, any improvements are very welcome! You can find the source here:
