FAQ

Common questions

How is LangBlitz different from other vocabulary apps?
Most vocabulary apps rely on plain flashcard memorization. LangBlitz uses the FSRS spaced repetition algorithm to schedule reviews based on how well you actually remember each word, and every card includes definitions, nuance, example sentences, collocations, etymology, and common mistakes, so you learn real usage, not just a dictionary definition.
What's included in the free version?
Free users get full access to 15 word cards plus the Word of the Day free widget, and can browse all 119 topic groups. Premium unlocks unlimited card access, unlimited quiz sessions, and the complete 5,000+ word library.
Is LangBlitz useful for exam prep like IELTS, TOEFL, or GRE?
Yes. Many word cards carry relevance tags for IELTS, TOEFL, GRE, GMAT, and CAT, so you can focus on vocabulary that commonly appears in the exam you're preparing for while still building broader, everyday English fluency.
Does LangBlitz need an internet connection?
No. LangBlitz works completely offline after installation, with no account required. Progress stays on your device, with optional backup and restore for Premium users.
