4Player vs FieldSketch

A Simple App for Recording and Saving 4-Player Mahjong Scores. With this app, you can easily record and save your 4-Player Mahjong (Yonma) game results. By pre-registering players, such as "friends," "family," and "online game opponents," along with game rules, you can effortlessly log scores. Recorded results are automatically organized by date, making it easy to find past match results at any time. [Game Result Recording] You can enter "date," "game rules," "players," and "scores" to record match results. Additionally, after entering scores for two players, you can use the "Auto Calculation" button to automatically calculate and fill in the last player's score. [Automatic Organization of Game Results] All recorded game results are automatically categorized and listed by date. This allows you to quickly find and review past match results when needed. [Game Result Aggregation & Score Trend Graph Output] By selecting a "date" and "players," you can aggregate game results and visualize score trends with a graph. This helps in tracking score progression over time. [Player Management] You can centrally manage various players, including "friends," "family," and "online game opponents." Registered players can be easily selected when recording game results. [Game Rule Management] You can manage Mahjong game rules all in one place.
