About this app

Books in German, English, Spanish and other languages — with a translation under every line and every phrase explained. Real books, at your level.

ReLemma isn't flashcards or streaks. It's the thing that actually works: reading a lot of text you can understand. We give you real books — The Little Prince, Sherlock Holmes, Anna Karenina, Don Quixote — and just enough help to finish them.

Open a book and read. Every line has a translation underneath, so you keep moving even when a sentence is hard. Tap any word or phrase and ReLemma doesn't just translate it — it explains why it means what it means: the grammar, the collocation, the idiom a dictionary would never catch. That "why" is how the language actually goes in.

Too hard? Drop the same book to B1 or A2 — the story stays, the language gets simpler. Ready for more? Read it in the original.

Learning German because you live in Germany or Austria? Start with a book in German adapted to A2 or B1: the translation isn't on the facing page, as in parallel-text books, but right under every line, and any phrase is explained with one tap. German sinks in through reading, not drilling.

• Learn by reading real books, not exercises — a growing public-domain library
• Tap to understand: meaning, grammar, and the why behind every phrase
• Graded books: A2, B1, B2 or the original — the classic adapts to you
• German, English, Spanish, French, Italian, Portuguese and many more
• Listen in a natural voice; choose accent and speed
• Save the words and phrases you meet, review them when you like
• Bring your own EPUB (Pro) — it stays private to your account

No streaks to keep. No flashcards to grind. Just books — and the language that comes with them.

Don't learn to read. Read to learn.
