Three ways to add words

Type the original and the translation into two columns, write pairs on one line as "rodzina: family, kawa: coffee", or upload a .csv, .tsv, .txt or .json file. A third column holds the transcription, so you always know how a word sounds.

Spaced repetition that respects your time

Every answer moves a card between five boxes with intervals of one, three, seven, fourteen and thirty days. Cards you keep missing come back within the same session, cards you know step aside. The deck list shows how many are due today.
