Skill & EMA Ratings

67-Parameter Ruleset Engine
Configure custom uma, oka, chombo penalties, or load official presets like EMA 2025 and Mahjong Soul. Once games have been played under a ruleset its scoring locks, so past results can never be rewritten.
In-Person Companion
At the table
A responsive digital companion built for live tables. Track winds, calculate complex hands, and keep games flowing smoothly.
Live Table Compass & Wind Rotation
Place a phone at the center of the table. The digital compass tracks current round, honba, riichi sticks, dealer seat, and automatic wind rotations with screen wake lock.
Three Ways to Record a Hand
Every winning hand is entered the way the table wants it: han / fu for a table that already counted, pick yaku to name the yaku and dora and let the score be worked out, or the full hand tile by tile. Scoring is settled server-side against your club's active ruleset, so nobody argues with the phone.
Full Hand Entry, Tile by Tile
Lay the whole hand into the app: concealed tiles and the winning tile, called melds, dora and ura-dora indicators, riichi and ippatsu. Fu and han are derived from the hand itself — no counting on your fingers — and the finished hand is kept with the round, so a disputed score can be re-read months later.
