🧮 Solo dev. Planning a 5-people Asia trip in InkCalc, no spreadsheet needed. "Tokyo→Bangkok 78000 × 5 + Bangkok hotel 14000 × 4 + Chiang Mai train 6500 × 5 + food per day 4000 × 5 × 7" → 78000*5 + 14000*4 + 6500*5 + 4000*5*7 = 618500 JPY Each component stays as a note. When one person can't make it, you change "5" to "4" and the whole trip re-prices in one keystroke. Now on the Mac App Store (free). #buildinpublic #indiedev #macOS
