Per-card accuracy, mastery percentages, weak-area surfacing, and pre/post learning-gain reporting — the outcome metric institutions actually buy.
Most apps measure engagement: streaks, screen time, cards-per-day. Those feel good and prove nothing. We measure the thing that actually matters — the pre/post test delta. Take a baseline before you study and a post-test after, and the system displays your real learning gain, exportable for students, parents, and teachers. Underneath, per-card accuracy, mastery percentages, and error-pattern analysis show not just what you got wrong, but the systematic misconception behind it.
Baseline before, post-test after — the measured delta is displayed clearly and exports for parents, teachers, and institutional buyers.
A granular graph of how often each card is answered correctly — see mastery build card by card.
Automatically isolates the smallest subset of content responsible for the most errors, so review effort lands where it counts.
Goes beyond 'you got this wrong' to name the recurring reasoning error or systematic misconception across sessions.
Take a baseline, study, then prove the gain with a post-test and an exportable report.
