GerLan vs Duolingo: Which App Teaches German Better?
Honest comparison of both approaches — and why you might want to use both.
Duolingo has 500 million users and deserves credit for making language learning accessible. But among serious German learners, it has a well-known problem: you can reach "advanced" levels on Duolingo while still being unable to hold a basic conversation. GerLan was built to fix exactly that.
The Cognate Advantage
GerLan starts every learner with English-German cognates — words that look and sound the same. This means Day 1 learners can read real German sentences immediately. Duolingo's course starts with scattered vocabulary without this structural insight.
Spaced Repetition
Both apps use spaced repetition, but GerLan's SM-2 algorithm is transparent and customizable. You can export your vocabulary to Anki, track SRS levels per word, and see exactly when each word is due for review.
Grammar Coverage
Duolingo famously under-explains grammar. GerLan includes 15+ grammar guides covering cases, verb conjugation, separable verbs, modal verbs, adjective endings, and more — each with clear rules and examples rather than passive exposure.
Our Honest Advice
Use both. Duolingo's streaks and gamification are motivating for building habits. GerLan provides the structural knowledge, vocabulary depth, and grammar understanding that Duolingo skips. Together, they cover more ground than either alone.
