About this app

Learning and then forgetting is the same as not learning at all.

If a learning app lacks a review system, you won't absorb much from even a large number of courses.

Tomaru uses spaced repetition to help you truly transform learned words into long-term memory.

**How ​​does Tomaru help you truly learn a language well?**

【Spaced Repetition Vocabulary Learning】
Based on the FSRS spaced repetition algorithm, this vocabulary learning system ensures you no longer forget what you've learned.

Have you ever had the experience of diligently studying a large amount of material, only to find yourself unable to recall any of it when you actually need to use it?

Scientific research shows that achieving the following two points can significantly improve long-term memory retention:

① Relearn when you're about to forget.

② Actively recall when you're about to forget.

Tomaru's spaced repetition system is designed for this purpose. Algorithms calculate the time when you're about to forget, allowing you to review and memorize less, remember more.

【Public Vocabulary Flashcards】
Tomaru offers a large number of public vocabulary flashcards for various languages, exams, and everyday life. Each word includes a complete image, example sentence, part of speech, pronunciation, phonetic transcription, and root word association. You can choose the desired flashcards and specific goals based on your level and objectives. No more searching for words to memorize everywhere!

【One-Click Vocabulary Addition】 Have a song, article, or textbook you want to learn? Copy and paste it, and Tomara will extract the words and create a personalized vocabulary flashcard pack for you.

【AI Personalized Practice】
Tomaru will prioritize using the words you've learned to generate personalized practice questions for you.

• Shadow Reading - Real-person sentence repetition helps you quickly practice listening and speaking skills.

• Two-way translation - The system generates articles based on your level and vocabulary. During the translation process, you'll discover your weaknesses, and AI will check your translation and offer suggestions.

• Grammar practice - The system generates questions based on your level and vocabulary, allowing you to quickly practice the subtle differences in all commonly used grammar rules. AI will also provide complete explanations of specific usages.

【Immersive Learning】 Built-in customizable ambient sound effects (rain, city, ditch fire) help you quickly enter a flow learning state.
