Create cards with text, images, audio recordings, and LaTeX maths equations.
Native iOS and Android apps so you can study wherever you are.
Organise your cards into colour-coded subjects with min/max interval settings.
Set caps for new cards and reviews per day so you don't burn out.
Auto-generate questions from your notes, get answers graded, and see where to focus.
Write a question and a model answer. Add images, audio, or maths if you need to. Group cards into subjects.
Each day, MindSpacer shows you the cards that are due. Rate how well you knew each one, and the schedule adjusts.
Cards you know well appear less often. Over time you review less but remember more.
Research on the forgetting curve shows you can lose most of what you studied within days. Spaced repetition counters this by timing your reviews at the point where you're about to forget.
