Vocaber is an advanced flashcard app for Android and iPhone (soon) that helps you build vocabulary through dynamic sentence exposure. Inspired by immersion and input-based methods (including Stephen Krashen’s theories), it offers up to 20,000 word forms per language.

Vocaber is designed for learners who already know the basics or are familiar with a related language. If you’re brand new, we recommend reviewing the alphabet and core grammar first.

Vocaber emphasizes learning through context and input, not grammar rules. For explanations, we suggest using external resources or grammar guides.

Short sentences allow quicker exposure to more vocabulary. For deeper comprehension, pair Vocaber with native content in your target language.

Sentences advance based on your performance. New material follows the N+1 principle - introducing just one new word or concept at a time.

Language exposure isn’t linear. Seeing complex grammar early helps you build passive familiarity, even before full understanding sets in.

Up to 20,000 word forms per language - aligned with a C2 vocabulary range. Actual coverage varies by language structure.

Vocaber uses CEFR as a general reference for vocabulary difficulty. For official certification, a formal CEFR exam is required.

Not at all. Real-world exposure complements spaced repetition and reinforces learning.

We don’t use ads or sell user data. Subscriptions support the infrastructure needed to maintain a high-quality learning experience. Try it free for 30 days to see if it’s right for you.

Duolingo is great for beginners and gamified learning. Vocaber is for learners ready to expand vocabulary through fast, focused sentence practice - without the handholding.

Vocaber builds on the spaced repetition model with language-specific features, dynamic sentence generation, and a more intuitive experience. Try both and see which works better for you.

Each word is tracked individually across varied sentence contexts, maximizing exposure and review efficiency.

You encounter words in different contexts, which deepens your understanding and avoids rote memorization.

Vocaber minimizes decision fatigue. If you don’t know a word, just tap it and move on - no complex review options to manage.

A web version is in development - stay tuned!

Liaisons vary by formality, region, and speaker. Our audio reflects this natural variation.
