When you see a word, can you recall both how it is read and what it means?
MASUMASU is built around that moment of recall. Study 7,400+ words from N5 through N1. Before revealing the answer, retrieve the reading and meaning from memory. If either one slips, the word returns in the next round—so familiar words move quickly and uncertain ones get more attention.
