Most of what you learn is gone within a week. Curio gives you one real idea a day, like why the Moon changes shape or why sequels disappoint, taught in a few minutes with visual cards and questions that make you think. Then it brings each idea back right before you'd forget it, with a new question each time, until it's locked in. 254 hand-written ideas across 16 topics, in paths that unlock chapter by chapter. Free on iPhone, no ads, no account.
