Riichi Mahjong Pocket

Riichi Mahjong Pocket is a pocket-sized helper for Japanese riichi mahjong. Open it mid-game to count fu, work out the score, settle the game, or look up a yaku.
It's handy for quick checks during play and for brushing up on the rules, helping beginners learn and supporting intermediate players at the table.
No ads, no sign-up. Core features — fu and score calculation, settlement, and the yaku list — work offline. (Online access is used mainly for in-app purchase checks, purchase processing, and app updates.)
