Spaced Repetition Tracker
What it is
Spaced Repetition Tracker is a study app for iOS and macOS that logs study sessions, records recall difficulty, and schedules when to review material again. Its SM-2 scheduling adjusts review timing based on ratings of Easy, Good, Hard, or Extremely Hard. Users can instead choose fixed intervals or predefined and custom review plans.
Coursework can be organized by subjects, groups, and topics, with a review queue, timeline, calendar and session history, reminders, and iOS widgets. The app can schedule material studied through textbooks, lectures, question banks, notes, videos, cases, and flashcards. Review events can be added to Apple Calendar and Google Calendar. The free plan includes up to two subjects with six topics each and unlimited sessions. Paid choices include $5.99 per month, $29.99 per year, $49.99 once for Unlimited Access, and $34.99 once for Unlimited Access (Family). User data is stored locally and synced through Apple's iCloud CloudKit private database, and is not shared with third parties or external services.
