"Boss pays more today", "The newbies get a discount", "Ladies pay less" — reflect the usual bill-splitting rules of Japanese drinking parties, year-end parties, and welcome/farewell dinners with a single tap. --- Key Features --- ■ Split Presets (6 types) Common Japanese group-dinner rules, each a single tap: ・Equal Split ・Boss Pays More (default 1.5x, adjustable) ・Organizer Free ・Newbie Discount (default 0.5x, adjustable) ・Ladies Discount (default 0.8x, adjustable) ・Non-Drinker Discount (default 0.7x, adjustable) Pick who's included via the chip on each member row. Multipliers are adjustable in ±0.05 steps on the card. ■ Dice Split (playful) Everyone rolls 0–9 randomly and the bill splits by the dice ratio. Example: 3 people, ¥1,000 total, dice 1/2/7 → ¥100 / ¥200 / ¥700. Includes a rolling animation and a re-roll button. Great party-ender. ■ Flexible Rounding ・Unit: ¥1 / ¥100 / ¥500 / ¥1000 ・Mode: "Leave remainder" (floor each) or "Collect extra" (ceil each) Great for "collect neatly in ¥1000 units" or "extra goes to tip". ■ Collection Tracking in Results Toggle each member as paid; a progress bar shows how much you've collected.
