Four Winds: Mahjong Score

Four Winds is a simple, private scorekeeper for American Mahjong (NMJL) game nights. Set up your table, track each hand as you play, and let the app handle the math — including the doubling rules for self-pick and concealed hands. See live standings as you go, review the full hand history, and get a final summary when the game wraps up. Works for 2, 3, or 4 players, so it's just as handy for a quick practice round as a full table. Four Winds keeps everything on your phone — no account, no internet connection required, and nothing ever leaves your device.
