## What is 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.)

◆ Free features

• Score table: quickly look up scores by fu and han
• Yaku list: search by name, keyword, han, or closed/open status (local yaku included)
• Settlement: enter the score difference from the starting points to calculate the winner's final points
• Memo: jot down house rules and anything else

• Settlement history: save, edit, and revisit your results (with export, import, and sharing)
• Lifetime stats: automatic per-player totals, with charts for rank distribution, cumulative points, and yakuman history
