Flips is a smart flashcard app designed for learning Japanese effectively.
It helps you review just before you forget, so you remember more with less effort.
Based on the science of memory and spaced repetition, Flips optimizes your timing automatically — letting you learn Japanese vocabulary, phrases, and kanji faster and retain them longer.
