Pass the B1 Goethe exam. Actually understand German.
A structured curriculum from A1 to B1 — with grammar that explains why, exercises that match the exam, and vocab that reviews itself.

Everything you need to reach B1. In one place.
- Apps are for light colloquial language learning.
- Textbooks have real structure and grammar, but lack modern digital features.
- Tutors are helpful, but expensive. 90% of learning happens during self-study and practice.
- Flash card apps are text only, they do not utilize visual memory and imagination.
We built OneWhoLearns to close the gaps and connect these different modes of learning together in a single unified platform.
One place to learn. Everything connected.
One Who Learns replaces your textbook, your apps, and your flashcard grind, and works alongside your tutor.
Memory palace flashcards
Learn vocabulary through image-based association — not rote repetition. Each word is paired with a visual scene that anchors meaning in memory. Combined with spaced repetition: forget a word, it comes back more often.

Structured curriculum mapped to the exam
30 Lektionen from A1 to B1. Not random topics — a grammar spine that builds systematically. Every exercise type maps to what the Goethe B1 exam actually tests.

Grammar that sets the foundation
Theory blocks before exercises explain the rule in plain language. "The Dative case marks the indirect object — the person receiving something." Not "fill in der/dem/den and figure it out."

Ready-made word lists for every level
A1, A2, and B1 vocabulary lists — already built, organized by Lektion, ready to study. Customize them: add your own words, remove what you already know.

Interactive reference tables
All core tables — irregular verbs, case declensions, article endings, preposition groups — built into the app and interactive. Tap a cell, see examples.

Connect your AI and MCP
Expose your learning data to your personal AI through the Model Context Protocol. Your AI grades, explains grammar in context, and adapts to your level.

Questions you probably have
Duolingo teaches phrases through pattern matching. It never explains why German grammar works the way it does. One Who Learns is a structured curriculum. 30 units with theory blocks, grammar drills, and exam-style exercises. Your vocab reviews itself through spaced repetition. You do not need a separate flashcard app.
Yes. Exercise formats mirror the Goethe exam: Leseverstehen, Hörverstehen, Schreiben, and grammar sections. Progress is tracked by grammar point, not streaks. At B1, the final unit is a full exam strategy module for Lesen, Hören, Schreiben, and Sprechen.
Your tutor gives you 1 to 2 hours a week. What about the other 5 to 10 hours of study? That is where One Who Learns lives. The tutor focuses on speaking and correction. The platform handles grammar, retention, and structure between sessions. They complement each other.
A1 is free to try. A2 and B1 unlock with Premium at EUR 12/month or EUR 99/year, less than a single private tutor session.
No, and we are upfront about that. One Who Learns covers reading, listening, writing, grammar, and vocabulary. That is 3 of 4 Goethe exam modules plus the foundation for all of them. For speaking, pair the app with a tutor, a tandem partner, or an AI assistant.
A1 is free with no time limit. Sections take 10 to 15 minutes each, built for real schedules, not idealised ones. Vocab reviews automatically, so even sporadic sessions still build retention.
The curriculum follows the grammar progression of Hueber Motive, a textbook used in German universities and Sprachschulen. Exercise types map to the Goethe B1 exam format. We built this to pass the exam, not to gamify learning.
