FAQ – Frequently Asked Questions About Readavo

Readavo is an English vocabulary app that teaches words through reading adapted articles. You read, tap unfamiliar words for instant translation and pronunciation, save them, and review with FSRS spaced repetition. 15-20 minutes daily builds 150-300 permanent words per month.

Duolingo teaches through gamified exercises; Readavo teaches through real reading. Duolingo builds ~100 words/month; Readavo builds 150-300. Duolingo uses generic content; Readavo adapts articles to your level and interests. Both are valid tools – Readavo is specifically optimized for vocabulary.

A1 (complete beginner) through B2 (upper intermediate). The system automatically selects articles matching your level: beginners get simple adapted stories with cognates, advanced learners get original BBC and Guardian articles.

Yes. A1 texts use cognates (hotel, taxi, restaurant) and the top 100 English words. You only need to know the Latin alphabet. Within 3 months, most beginners reach 500 words and A2 level. See our from scratch guide.

FSRS (Free Spaced Repetition Scheduler) is a 2022 machine learning algorithm that calculates when you're about to forget each word and schedules a review at exactly that moment. Research suggests it schedules reviews more optimally than older algorithms like SM-2 (used by Anki). Learn more about FSRS.

2 weeks: you notice familiar words in movies and songs. 1 month: 100-150 new words, reading feels easier. 3 months: 500+ words, noticeable level improvement. 6 months: confident at the next CEFR level.

5-15 new words per day is optimal. More than 20 overwhelms working memory and reduces retention. Quality over quantity: 10 well-learned words beat 30 half-remembered ones. FSRS manages the pace automatically.

Readavo focuses on vocabulary through reading. Grammar is absorbed naturally through exposure to correct patterns in real texts. For explicit grammar study, combine Readavo with a grammar resource. Most learners find that daily reading teaches grammar patterns implicitly within 2-3 months.

A1: 500 words (basic survival). A2: 1000-1500 (everyday situations). B1: 2500-3000 (independent user). B2: 4000-5000 (upper intermediate, professional). These are active vocabulary targets.
