## Description

ReBrain is a flashcard learning app powered by a spaced repetition algorithm based on the forgetting curve.
Instead of simple repetition, cards are shown at the optimal timing based on how well you remember them—helping you learn efficiently and retain information long-term.

Features
・Multiple study modes: Learn with flashcards, typing, multiple-choice quizzes, and red-sheet mode.
・Quick Search: Instantly look up words with a single tap.
・Smart Study: Review based on the forgetting curve. Cards you struggle with appear more frequently, while well-learned cards appear less often.
・Custom themes (Pro): Personalize the app with different colors, fonts, and icons.

There are no ads in the app, and all learning-related features are completely free.
Additional customization options require a purchase.
