Fathom is a free geography learning game and quiz played on an interactive 3D globe. Spin a photorealistic Earth and click directly on countries, cities, seas, and mountains to answer.
Built-in Leitner box spaced repetition tracks what you know and resurfaces what you struggle with across sessions, days, and weeks, building real long-term memory, not just short-term recall.
