## What is 雀の羽算用?

This app is a collection of useful gadgets designed for Japanese Mahjong games — a handy “table companion” you can keep beside the Mahjong table.

You can easily access practical tools for checking seat wind and round wind, confirming Mahjong tile kanji, calculating scores and fu, and verifying score consistency after a match.

From simple reference tools such as the Wind Indicator and Score Table to practical utilities like the Mahjong Calculator, Result Calculator, and Easy Fu!, the app supports players both during and after Mahjong games.

Designed to serve as a reliable “friend on the table” for Mahjong players.
