Built for students, self-learners, and anyone who wants to memorize and retain what they read. Use it as your personal study planner and revision tracker. ā HOW IT WORKS ā Add a topic after a lecture, a textbook chapter, or a podcast. Itari uses a proven spaced repetition algorithm (FSRS) to schedule your next review at the optimal time. Each review strengthens memory and pushes the next one further out. ā GENTLE BY DESIGN ā No red streaks. No guilt. Itari is calm on purpose. Reviews take a few minutes, and the tone stays encouraging whether you nail it or need another pass. ā FEATURES ā ⢠Spaced repetition scheduling ā reviews arrive when your memory needs them ⢠Flashcard reviews ā see the topic, recall what you know, reveal the answer ⢠Memory strength tracking ā watch each topic's retention grow over time ⢠Organize by subject ā group topics into color-coded categories ⢠Weekly stats ā see reviews completed, topics added, and overall retention ⢠4 reading themes ā Lumen, Ink, Sepia, and Mist, each tuned for long sessions ⢠CloudKit sync ā your topics stay in sync across iPhone and iPad ⢠Privacy-first ā your data stays on your devices, synced via your iCloud ā WHO IS ITARI FOR ā ⢠Medical students memorizing anatomy, pharmacology, and pathology ⢠Law students retaining case law, statutes, and legal principles ⢠Language learners drilling vocabulary, grammar, and conjugation ⢠Engineering students reviewing formulas, theorems, and concepts ⢠Anyone preparing for board exams, bar exams, quizzes, or certifications ā THE SCIENCE ā Spaced repetition is one of the most evidence-backed study techniques in cognitive science.
