Works well. Interface can be tricky to work with. Can't do 7 pairs but that's not a huge limitation.

Awesome really helps me, I did notice it didn't have anything to calculate 7 pairs? Is there a reason for that or am I still to much of a noob?

Do you think you could add the values for han and fu so we can practice calculating in our heads? for example, riichi 1 han, ippatsu 1 han, 1x pon is such and such fu, etc? Thanks.
