Frequently Asked Questions

What is MosaLingua?

MosaLingua's entire pitch is one line: focus on the 20% of a language you'll need in 80% of situations. That is not a slogan so much as the actual method — the MosaLearning approach applies spaced repetition to a deliberately curated core vocabulary rather than an exhaustive one, and reviews words right before you would otherwise forget them. For a learner who wants results rather than completeness, that focus is the whole appeal.
