Koki SRS Flashcards APP

Koki SRS Flashcards is a flashcard app for learning vocabulary with spaced repetition (SRS). Study English vocabulary, IELTS vocabulary, JLPT vocabulary, Minna no Nihongo, HSK flashcards, TOPIK vocabulary and more.

Use ready-made vocabulary flashcards or create your own with our flashcard maker. Koki helps you study smarter by showing difficult cards more often and reviewing familiar cards less frequently.

SRS FLASHCARDS & SPACED REPETITION

Koki uses spaced repetition (SRS) to schedule flashcards based on how well you remember them.

Difficult vocabulary appears more often, while words you already know are reviewed less frequently. This helps you focus your study time on the cards that need the most attention.

Whether you are looking for a spaced repetition app, SRS flashcards or an easy way to study vocabulary, Koki gives you a simple and flexible review system.
