## prismCalc Description
Split a dinner bill in seconds. Check a discount before you buy. Compare loan payments side by side. prismCalc is the everyday calculator for the math that happens outside a spreadsheet — beautiful glass design, no ads, no tracking.

**LIVE CALCULATION PREVIEW**
• See the running result while you build an expression
• Keep enough context on screen to catch mistakes before pressing equals

**KEEP RECENT RESULTS CLOSE**
• Dynamic Island can keep your last calculation visible while you switch apps
• Widgets and quick actions help you get back to recent math without digging through the app
• History lets you reuse prior calculator, tip, discount, loan, and conversion entries

**CORE CALCULATOR**
• Large calculator buttons with haptic feedback
• Memory functions (M+, M−, MC, MR) with indicator dot
• Long-press display to copy, double-tap to paste
• Standard or alternate key layout — choose what feels natural
• Display gestures for backspace, undo backspace, recall, clear, copy, and paste

**EVERYDAY TOOLS (Pro)**
• 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
• Unit Converter — 38 length, weight, volume, and temperature units, with Metric, US Customary, and Imperial results grouped clearly

**HISTORY & NOTES (Pro)**
• Save, review, search, and filter past calculations
• Name and pin saved calculations so important bills, payoff plans, and conversions are easier to find later
• Mortgage scenarios save with full escrow context (property tax, insurance, HOA, escrow toggle) so reopening a saved payoff plan restores the exact inputs
• 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

**ALWAYS WITHIN REACH**
• Home Screen widgets — small, medium, and large (all free)
• Lock Screen widgets — accessory circular, rectangular, and inline (free)
• Control Center widgets — quick actions for calculator, tip, split, discount, unit converter, loan, and copy last result
• Siri Shortcuts — calculate tips, split bills, convert units including volume, and recall recent results
• Apple Watch companion — calculator, tip, discount, and split right on your wrist with all 10 themes synced

**THEMES AND LAYOUT**
• Animated mesh gradient backgrounds with true glassmorphism
• 4 free themes (Aurora, Calming Blues, Dark Glass, Pearl) plus 6 Pro themes
• Square or round buttons, plus standard or alternate key layout

**PRIVACY FIRST**
• No tracking, no analytics, no ads, no account required
• Your data stays on your device unless you choose optional iCloud Sync

**ACCESSIBILITY**
• VoiceOver, Dynamic Type, Increase Contrast, Reduced Motion, and alternative key layout
