Studyline turns six flashcard formats into interactive practice. Create Question, Definition, Fill Blank, True/False, Sequence, and Scenario cards - then reveal and rate, type missing words, choose true or false, arrange steps, or compare your response with a rubric. Mixed Practice uses each card’s format automatically, or choose a specific method for the whole session. • Study what matters - Review All, Due, or Weak cards from your full library, any folder, or one set. • Shape each session - Study in order or shuffle, use no timer, a stopwatch, or a countdown timer, and continue unfinished sessions. • Create with less friction - Add one card at a time, type or paste many, or import CSV, TSV, and TXT files. • Keep everything organized - Use folders, nested subfolders, and sets. Search your library, sort cards within a set, archive and restore sets or cards, and add exam dates. • Stay on track - Rate your recall as Again, Hard, Good, or Easy to schedule the card’s next review. Set a daily goal and optional reminder, while Today brings due and weak cards, unfinished sessions, and Up Next sets together. • See your progress - Track confident recall, recall trends, cards reviewed, study time, active days, streaks, goal progress, weak sets, and session history. Start a weak-card review directly from Stats. Your cards, progress, and study history stay on your device, with no account required. Create a restorable Library & Stats backup when you choose, restore it as a separate copy, or export active cards to spreadsheet-ready CSV. Designed for focused practice on iPhone and iPad.
