다이쏭’s Seven-Floor Calculator Shop

Field notes

The site uses a department-store metaphor to arrange Korean rule-based calculators by situation, from academy refunds and airline delays to housing, payroll, trekking, and freelance withholding. The visible examples attach outputs to concrete cases: a 150,000-won academy refund and a 128,000-won estimate for a four-hour international delay on a 640,000-won fare. Several planned tools would extend the same pattern into document generation, including a refund-demand letter, a payroll PDF, and an ICS work calendar.
