Frequently Asked Questions
Everything you need to know about LangMR and spaced repetition
What is spaced repetition and why does it work for language learning?
Spaced repetition is a scientifically proven learning method that shows you vocabulary at increasing intervals — right before you would forget a word. Based on the spacing effect discovered by Hermann Ebbinghaus, this technique produces 200–300% better long-term retention than cramming. LangMR's adaptive algorithm adjusts review timing to your personal performance on each word, making your study sessions shorter and more effective over time.
Which languages does LangMR support?
LangMR supports 14 languages: Russian, English, Arabic, German, Spanish, Persian (Farsi), Finnish, French, Hindi, Portuguese, Romanian, Belarusian, Swedish, and Turkish. The app interface is fully localized in all 14 languages. Russian is the primary flagship language with the deepest vocabulary content, and all other languages are fully supported for study and review.
Can I use LangMR without internet?
Yes — LangMR includes a full offline mode. After your vocabulary lists and audio are downloaded once, you can study flashcards, hear text-to-speech pronunciation, and track streaks with no internet required. This makes it ideal for commuting, travel, or study in areas with poor connectivity.
How is LangMR different from Duolingo?
Duolingo uses gamified daily lessons focused on phrases and sentences. LangMR uses strict spaced repetition to optimize exactly when each word is reviewed, which is more effective for long-term vocabulary retention. LangMR also supports PDF vocabulary import, unlimited custom word lists, and full offline mode — none of which Duolingo offers. LangMR is the better choice if your goal is systematic vocabulary mastery rather than casual daily streaks.
Is LangMR a good Anki alternative?
Yes. Anki is a powerful open-source flashcard tool but requires significant setup: you must build your own decks, configure card formats, and manage settings manually. LangMR is purpose-built for language learning with built-in audio, PDF import, achievement tracking, and a clean mobile-first interface — no configuration required. If you want spaced repetition without the technical overhead, LangMR is a more accessible alternative to Anki for language learners.
