Studying alone is quiet, flexible, and very easy to quietly stop doing.
Share a deck in one link
Send any deck or course as a link. Whoever opens it can preview it and save their own copy in one click, without an account setup ritual first. One person builds the deck for the module and everyone has it.
Quiz duels
A real-time multiplayer quiz on any deck or topic, with a live leaderboard while you play. It takes a few minutes and it is genuine retrieval practice, which is the thing that actually builds memory. Being beaten by a friend on a question you were sure of corrects the mistake better than any progress bar.
Study groups
Create a group, share decks inside it, see each other's progress, watch a daily leaderboard. The leaderboard is not really the point. The point is that other people can see whether you studied, which works on most of us. On the free plan the number of groups is limited, and Premium removes the limit.
Mountain Max
A 3D runner game where you answer questions from your deck while dodging obstacles. It is exactly as serious as it sounds, and it gets used for the twenty minutes when the alternative was not studying at all.
