Retentive - Spaced Repetition

Spaced repetition lets you remember almost anything — but with so much to study, when do you review it all? Retentive schedules each one for you. Watch it stick for good.

Retentive tells you exactly what to review and when - so the hours you study actually stick.

Organise everything you're learning into subjects, topics and items, choose a learning mode that matches your deadline (from night-before cramming to slow long-term mastery), and Retentive builds the review schedule for you. Review on time, earn points, keep your streak alive, and watch topics climb toward Mastered.

WHY SPACED REPETITION WORKS Your brain forgets on a predictable curve. Reviewing just before you forget resets that curve and locks knowledge into long-term memory. Retentive is built entirely around this science - the right reviews at the right time, nothing else.

NOT ANOTHER FLASHCARD APP No deck-building required. Retentive schedules whatever you already study - lecture notes, textbook chapters, problem sets, past papers. Add an item once; the schedule does the thinking.

FIVE LEARNING MODES From Ultra Cram for tomorrow's exam to Extended for knowledge you want to keep for years - each mode times its reviews differently, and you can mix modes across topics.

FOCUS TIMER + WIDGET Run distraction-free focus sessions on any topic, see how well you stick to them, and keep today's plan in view with the home-screen widget.

PROGRESS YOU CAN SEE Points, levels, streaks, achievements, and a full statistics screen covering study time, review accuracy, and mastery across every subject.
