Kioku

Kioku — flashcards for learning vocabulary

A simple app for memorizing words with flashcards. Built with a focus on Japanese, with more languages already coming.

**Catalog of premade sets**
Open the catalog, pick what you want to learn — hiragana, katakana, the 214 kanji radicals — and add it to your decks in one tap. New sets are released regularly.

**Textbooks — practice alongside your classes**
Subscribers get ready decks for popular textbooks, split by lesson. Practice a single lesson or the whole textbook at once. The list keeps growing.

**Three modes to stay engaged**
- Flashcards — flip cards and test yourself
- Quiz — pick the correct answer from four options
- Drawing — write kanji by hand

**Daily goal and streaks**
Set a daily target (10 / 25 / 50 / 100 cards) and track your streak — how many days in a row you've practiced. The dashboard shows weekly progress and accuracy per deck.

**A few more perks**
- Works offline — everything is stored on your device
- Cross-device sync for subscribers
- Sign in with email, Google or Telegram
- Interface in 5 languages: Russian, English, Spanish, Chinese, Japanese

Build your own decks or take the premade ones — and just learn!
