English Vocabulary App – Readavo: Learn Words Through Reading

Readavo combines adapted articles, instant translation, pronunciation, and FSRS spaced repetition into a single learning workflow. Words learned in context stick far better than flashcard lists. Free plan available – no installation required.

Contextual Translation

Tap any word – see translation, transcription, example sentence. The word is saved with its original context for richer review.

FSRS Spaced Repetition

2022 machine learning algorithm calculates optimal review timing for each word individually. No manual scheduling needed.

Native Pronunciation

Every word has TTS audio. Hear correct pronunciation from day one – relearning later is 5x harder.

Adapted Articles

Articles matched to your level: ~90% known words, ~10% new. Optimal balance for growth without frustration.

Readavo vs Anki vs Quizlet vs Duolingo

Anki: Powerful flashcards but no built-in reading. You create cards manually. Complex interface. Uses SM-2 (1987 algorithm).

Quizlet: Simple flashcards without spaced repetition. Good for test prep, not for long-term retention.

Duolingo: Gamified sentences, but vocabulary growth is slow (~100 words per month) and lacks real-world context.

Readavo: Read – translate – review in one workflow. FSRS (2022) instead of SM-2. No card creation needed. Level-adapted real articles. 150-300 words/month.

Free vs PRO

Free plan: Daily reading (1 article), translation, pronunciation, FSRS review, basic stats. Limited new words per day. No time limit – free forever.

PRO: Unlimited new words, extended statistics (accuracy by exercise type, level growth, progress history), priority support. Same learning method for both plans.

Devices

Readavo works on any device with a browser: iPhone, Android, iPad, laptop, desktop. PWA support lets you add it to your home screen. Data syncs across devices via your account.

Free Plan – Not a Trial

Readavo's free plan isn't a 7-day trial. It's a full learning method with no expiration. Use it for a year, two, five – as long as you need. PRO adds more words per day and detailed analytics.

Not Flashcards

Words in real article context – far better recall.

FSRS 2022

Next-generation ML algorithm – predicts the forgetting moment more precisely than SM-2.

PWA App

Add to home screen – looks and feels like a native app.
