prismCalc

prismCalc is an everyday calculator for the math that tends to happen outside a spreadsheet: splitting a dinner bill, checking a discount, comparing loan payments, converting units, or reusing a result from earlier in the day. It runs on iPhone, iPad, Mac, and Apple Watch, with a consistent glass-style interface and no tracking.

**KEEP RECENT RESULTS CLOSE**

• Tip & Split — tips, equal splits, rounded per-person totals, and by-share splits for uneven groups
• Discount Calculator — original price, savings, sale price, and tax
• Loan Calculator — mortgage, auto, student, and personal loans. Mortgages lead with the total monthly payment, with principal + interest and escrow (property tax, insurance, HOA) as immediate context. Includes payoff planning, extra-payment what-ifs, and full amortization details

**HISTORY & NOTES (Pro)**
• Save, review, search, and filter past calculations

• Add notes to any calculation
• Share calculations with notes via Messages, Mail, or any app
• Lock important entries so they cannot be accidentally deleted
• Optional iCloud Sync across devices
