Metis is for people who already speak a second language or are learning one but keep forgetting the words they look up: idioms, slang, phrasal verbs, the expressions natives use. Search a word or phrase in either language and Metis builds a card with the translation, meaning and a real example. Spaced repetition brings it back at 1, 2, 4 and 7 days, in four review styles, until you know it. You can also share them with your friends. iPhone widget, 21 interface languages, free plan.
