Know It Cold

Learn a subject with a tutor, then keep it with spaced repetition.

Know It Cold is an iPhone app for learning a subject deeply and keeping it. You pick a topic, an AI tutor builds a curriculum and teaches it to you one node at a time, and everything you learn is scheduled for review so it stays known.
