Deep science, beautiful play.
fudami was built on a simple premise: the two tools learners actually use have never been fused. Anki has world-class memory science wrapped in a punishing interface; Duolingo has a brilliant habit loop with no real spaced repetition underneath. fudami is both halves done right: deep science that proves you're learning, and honest play that makes you want to come back.
