Riichi Mahjong Calculator

This is a Mahjong Calculator unlike any other. Tired of inputting tiles manually? Why not take a picture instead? Use the camera feature of this calculator to automatically recognize tiles and calculate the hand. Yes that's right, this app is equipped with tile recognition software. In addition, there are also various tool-tips that explain the various yaku, fu, han, and scoring calculations.

Disclaimer: The tile recognition software is not very accurate at the current date. Both the tile detection model and the classifier were trained on 2500 pictures of Yellow Mountain Imports white Riichi Mahjong tiles and 2000 other pictures manually scraped from the internet. Results may be less accurate on other tile sets.
