This app was released in May 2023.
I think there are many people who know terms such as yaku, hannumber, and machi no kata, but don't really understand the sign calculations.
In such a case, by using this app, you can easily find out the score by simply touching and selecting Shimenko, Suzumzu, Machi, Hanazu, etc.
Please note that this app assumes that you know terms such as yaku, face, and machi no kata, and we have developed it with the assumption that it will not be suitable for everyone.
※Notes
The following cases are currently not supported.
・In the case of seven pairs of children
・In the case of Yakuman (excluding counting Yakuman with 13 or more han)
・When considering stacking sticks and deposits
Also, this app does not use rounding up and mankan.
