Count, Split and Pay: All in One Mahjong App
An idea born out of playing mahjong with family over Chinese New Year, made to reduce the awkward settlement work after a game.

Why
Family games created repeated scoring and payment friction, and the useful product was the one that could count, split, and settle in a single flow.
How
The app keeps the flow narrow: record the game, calculate who owes what, and make the payment handoff obvious.
PengPay keeps the product small on purpose. The useful moment is not a broad
social game app; it is the handoff from scorekeeping to settlement.
