Short answers, plus a focused guide when you want the full workflow.
What is a spaced repetition tracker?+
A spaced repetition tracker records when you study a topic and schedules the next review after a delay. Spaced Repetition Tracker uses your session difficulty to adapt that delay, helping weaker topics return sooner and stronger topics wait longer.
Learn how spaced repetition worksHow do I make a spaced repetition schedule?+
Create small, reviewable topics, log your first session, and choose an adaptive, fixed, or preset schedule. With Smart Algorithm enabled, each Easy, Good, Hard, or Extremely Hard rating changes the next review date.
Build your review scheduleIs this an Anki alternative?+
It is an alternative for learners who want spaced repetition without making flashcards. Use your existing textbook, notes, question bank, videos, cases, or flashcards; the app tracks the topic and tells you when to return.
Compare the no-flashcard workflowCan spaced repetition save study time?+
It can make review more targeted by bringing difficult topics back sooner and spacing familiar material farther apart. The time saved varies by person and subject; it does not guarantee a fixed reduction.
See how spaced repetition worksCan I use spaced repetition for exam prep?+
Yes. Organize your syllabus into testable topics, retrieve before rereading, and let difficult topics cycle back sooner. Close to the exam, you can switch to a preset or custom plan that fits the remaining days.
Plan spaced repetition for examsHow do active recall and spaced repetition work together?+
Active recall is what you do during the session: retrieve without looking. Spaced repetition is when you repeat that retrieval. The app schedules the timing; you choose the best recall activity for the material.
Combine active recall and spacingDoes the app work for medical or law school?+
Yes. Topics can represent conditions, mechanisms, rules, cases, or issue clusters. Log question-bank sessions, case practice, outline recall, or any other study activity without duplicating your material.
See the medical school workflowWhat is the SM-2 algorithm?+
SM-2 is a classic adaptive scheduling algorithm. It uses recall quality, a repetition count, the current interval, and an ease factor to decide when a topic should return.
Understand the SM-2 algorithmDoes my study data sync between devices?+
The app syncs study data through iCloud when iCloud is available and enabled. Sync is managed by Apple's system and may take time; the app also includes a separate Backup & Restore option for exporting and importing a backup file.
