How KoKo makes words stick

You first recognise the word, then recall it from memory. Once learned, it comes back six times, at growing intervals: the next day, then 3 days, 8 days, 3 weeks, nearly 2 months and 4 months later. A session takes a few minutes, and KoKo never offers more than 32 reviews a day.
