Calculator, Tips, Mortgage

Free · In‑App Purchases

v1.1.1 mortgage results lead with total monthly cost. P+I + escrow at a glance. Tips, splits, discounts, loans, conversions, widgets, Siri. No ads. No tracking. 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. **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 — length, weight, volume, and temperature conversions **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 ACCESSIBLE** • Home Screen widgets — small, medium, and large with configurable display modes (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, High Contrast mode, Reduced Motion, and alternative key layout Built by a solo developer.

Small but meaningful fixes plus the first language localizations for German, Spanish, French, Japanese, and Brazilian Portuguese. Fixed: • The recent-calculations tape on the calculator no longer stays blurred after a successful Pro purchase — it now clears in real time instead of waiting for an app relaunch • VoiceOver announcements in Settings, About, and the Loan screen are tighter — the small decorative chevrons and section icons are now hidden from VoiceOver so each row reads as a single clear label • Loan screen layout rebalanced on iPad landscape so extra-payment what-ifs sit beside the amortization schedule they update, instead of pushing the inputs column below the screen Localized: • App Store listing now reads natively in German (Deutsch), Mexican Spanish (Español), French (Français), Japanese (日本語), and Brazilian Portuguese (Português brasileiro). The app interface remains English for now; long-form description and release notes will be localized in a future update once a native-speaker review pass is complete If you bought Pro and the calculator tape still looks blurred when you reopen the app, this update is the fix.
