Product
Nothing to configure first
Open couchduel.app, see tonight's date and two players, and tap +1. A guest game starts with no account, and saving your history later keeps every game you played as a guest. Each game is kept with its date, players, scores and winner, which feeds the running rivalry: all-time record, streaks and a month-by-month head-to-head.
Engineering
Scores that can't drift
Scoring is event-sourced: a total is always the sum of its events, and corrections are recorded, never erased. Every tap carries a unique key, so a retry on a flaky connection can't award a point twice, and scores update instantly with an honest rollback if a write fails. The app holds no service-role key; Postgres row-level security does the access control.
