Learn the 1000 German words that cover most of everyday speech. Every word comes with a simple German example sentence, so you meet it in context instead of memorising a bare translation. HOW IT WORKS WordLern uses the Leitner system, a flashcard method built on spaced repetition. Every word lives in one of five boxes. Answer correctly and it moves up a box and comes back later; answer wrong and it drops back and returns sooner. The words you find hard come around often, the ones you know get out of your way. A session is ten cards. That is all it takes. WHAT YOU GET - 1000 words, chosen from real German corpora - not translated from an English list - A simple German example sentence for every word - Pronunciation in the best German voice your device has installed - Nouns with their articles (das Haus) and verbs in the infinitive - Home screen and lock screen widgets showing your progress - A reminder that arrives when cards are actually due, not on a timer WHAT IT DOESN'T DO No account. No ads. No subscription. No analytics, no tracking, no data collected - the app makes no network calls at all. Everything stays on your device and works offline.

Verdict
The clearest difference is in-app purchases: WordLern at none against Owle's 4. WordLern also leads on ads (none vs shown). Owle's advantage is update cadence (every 6 weeks vs every 21 months) and iOS requirement (13.0 vs 17.5). On price and device support there is nothing between them.
