Hi Product Hunt! I'm Nguyen, the maker of Yuzu Sum.
Yuzu Sum is a notepad calculator: type one expression per line and the answer appears beside it, with a running page total.
• Variables, labels ("Rent: 7tr5"), notes and # headings that never break the totals.
• All nine Numi-style percentage forms, plus X + 10% and X − 10%.
• Units for length, mass, volume, area, temperature, data and duration, including Vietnamese ones like sào. Mixing dimensions is refused, never guessed.
• Exact decimal money math: 0.1 + 0.2 is 0.3.
• Currency conversion with Vietcombank buy/transfer/sell or mid-market rates, and Vietnamese money words: 500k, 1tr2, 2 tỷ. English works just as well.
It's a beta for macOS 14+. Tell me which calculations you want it to understand next!
