Repeater is a complete language learning app designed to help you learn vocabulary, remember new words, and improve memory using the proven spaced repetition method.

If you’ve ever studied vocabulary and forgotten it a few days later, you’re not alone. Traditional flashcards and word lists often rely on random repetition. Repeater uses a smart spaced repetition system that shows you words right before you’re about to forget them. This helps move vocabulary from short-term memory into long-term memory.

With consistent vocabulary practice, you don’t just review words — you truly remember them.

How spaced repetition works

Repeater tracks how well you know each word and automatically schedules reviews.

• Easy words appear less often
• Difficult words repeat more frequently
• Reviews are personalized to your progress
• No unnecessary repetitions

The spaced repetition algorithm adapts to your learning speed, making vocabulary learning efficient and structured. This language learning app works for any language and any level.

Learn vocabulary by reading books

Repeater is more than a flashcards app. You can read books directly inside the app and turn real content into vocabulary lessons.

• Upload and read your own books
• Read in your target language
• Highlight unfamiliar words while reading
• Instantly add new words to your study list
• Build personal vocabulary lists from books

Learning vocabulary through reading books helps you understand context, sentence structure, and real usage. Instead of memorizing isolated flashcards, you study words as they appear naturally in texts. This strengthens memory and improves reading skills at the same time.

Whether you’re reading fiction, non-fiction, or study materials, you can transform any book into an active vocabulary learning experience.

Practice with AI chat and learn from conversation

Repeater also includes AI chat to help you practice real communication while expanding vocabulary.

• Chat with AI in your target language
• Practice writing and conversation skills
• Discover new vocabulary during dialogue
• Add new words from AI chat directly to flashcards
• Review chat vocabulary using spaced repetition

AI chat allows you to learn vocabulary naturally through conversation. You use words in real sentences, then reinforce them with spaced repetition flashcards. This combination of AI chat and structured vocabulary practice makes language learning more interactive and practical.

Smart flashcards for long-term memory

Repeater’s flashcards are powered by a proven spaced repetition system inspired by cognitive science research.

• Adaptive spaced repetition scheduling
• Optimized for long-term memory
• Daily vocabulary reminders
• Study words at your own pace
• Efficient vocabulary training sessions

Spaced repetition is one of the most effective methods for memory improvement. With regular vocabulary practice, you retain more words in less time and reduce unnecessary reviews.

Track your language learning progress

Staying consistent is key in language learning. Repeater helps you track progress clearly and stay motivated.

• Monitor total words learned
• View review statistics
• Track daily study streaks
• Measure vocabulary growth over time

This language learning app supports beginners learning their first 500 words, intermediate learners expanding vocabulary, and advanced learners reading books in a foreign language.
