Anki

I really like Anki. It is a simple but very customizable application for spaced-repetition flashcards. If you’re interested in memory and memorization, you might enjoy it too, since it’s free, open-source, and cross-platform.

I also highly recommend adding the LPCG (Lyrics/Poetry Cloze Generator) plug-in if you are interested in memorizing poetry.

Here are some Anki decks I've created for myself:
