Detailed Review
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.
The catalogue is the widest of the vocabulary-first apps here, covering eleven languages including Mandarin, Arabic, Korean and Japanese alongside the usual European set, with vocabulary, grammar, reading, listening and speaking exercises rather than vocabulary alone. Business and exam-specific tracks (Business Spanish, TOEIC, TOEFL) sit alongside the general course, which is unusual breadth for an app this size.
MosaLingua is published from Lyon by digiSchool Group, a French company, with a free tier and premium subscriptions from around €7.49 a month on longer plans up to €9.99 monthly, plus one-off per-language packs from €5.99. The honest limit: MosaLingua teaches efficiently but does not put you in front of a person, so — like Lingvist and Speakly — it needs pairing with something that trains actual conversation.
