About this app

Forget what you learn, and it is as if you never learned it. Without a review system, even a learning app packed with courses will not help much of it stick. Tomaru uses spaced repetition for vocabulary, helping turn the words you study into genuine long-term memory. ** How Tomaru helps you truly learn a language **

[Learn vocabulary with spaced repetition]
Built on the FSRS spaced repetition algorithm, Tomaru’s vocabulary system helps you stop learning words only to forget them again. Have you ever studied a huge amount of material seriously, then could not recall any of it when you actually needed it? Scientific research shows that two actions can greatly improve long-term retention: ① Relearn something just before you forget it ② Actively recall it just before you forget it Tomaru’s spaced repetition system is designed for exactly this. The algorithm calculates when you are likely to forget and schedules your review. Study less. Remember more.

[Public vocabulary decks]
Tomaru offers a large collection of public vocabulary decks for different languages, exams, and everyday situations. Every word card includes an image, example sentence, part of speech, pronunciation, audio, and word-root associations. Choose a deck and a specific goal that match your level and objectives. No more searching everywhere for words to study.

[Add and translate words in one tap]
Have a song, article, or learning resource you want to study? Copy and paste it, and Tomaru extracts the vocabulary and turns it into your own deck. Wherever you read on your phone, you can translate text and quickly add words with one tap.

[Create your own decks]
Whatever you are learning, you can quickly create your own cards, including image-based cards.

[Personalized AI practice]
Tomaru prioritizes words you have already learned when generating personalized exercises.
• Shadowing — Follow along with natural recorded sentences to quickly practice listening and speaking
• Bidirectional translation — The system generates passages from your level and vocabulary. Translation reveals your weak points, and AI checks your work and offers suggestions
• Grammar practice — The system generates questions from your level and vocabulary so you can practice subtle differences between common grammar patterns, with detailed AI explanations
• Speaking practice — Practice with your own AI using prompts carefully designed by us. After each session, your conversation history can be analyzed to tailor the next practice

[Immersive learning]
Mix built-in ambient sounds such as rain, a city, and a campfire to enter a focused flow state faster. Questions? Visit the in-app Help Center or contact us: support@tomaruai.app Terms of Service: https://tomaruai.app/en/legal/terms Privacy Policy: https://tomaruai.app/en/legal/privacy
