## What is prismCalc?

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 — 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 WITHIN REACH**
• 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, Increase Contrast, Reduced Motion, and alternative key layout

## Version history (last 5 releases)

### 1.2.8 — 2026-08-10

Sidebar reliability on iPad.

• Hide and restore the sidebar across Calculator, Tip & Split, Discount, Loan, Converter, History, and Settings.
• Fixed missing and duplicate sidebar controls in portrait and landscape.
• Kept sidebar behavior stable through orientation changes.

### 1.2.7 — 2026-07-28

A focused iPad navigation reliability update.

Fixed:
• iPad sidebar controls are now native-only, preventing duplicate slide-out/sidebar buttons in portrait and collapsed layouts.
• Removed the app-owned mirror button path across Calculator, Tip & Split, Discount, Loan, Converter, History, and Settings.
• Added portrait and landscape rendered-surface QA coverage so duplicate system/app controls cannot slip through again.

### 1.2.6 — 2026-07-27

A focused iPad navigation reliability update.

Fixed:
• iPad sidebar controls now have one owner in every state: one Hide Sidebar control while expanded and one native restore control after collapse.
• Removed the duplicate expansion-button path across Calculator, Tip & Split, Discount, Loan, Converter, History, and Settings.
• Added direct rendered-surface QA coverage so simulator harness limitations cannot produce false greens.

### 1.2.5 — 2026-07-26

A focused navigation and history recovery update.

Fixed:
On iPad, every sidebar screen now keeps a reliable Show Sidebar button in the navigation bar whenever the sidebar is closed. This applies to Calculator, Tip & Split, Discount, Loan, Converter, History, and Settings.
The iPad sidebar control now stays in the same top-leading position as it switches between Hide Sidebar and Show Sidebar, so navigation feels consistent across apps.
We also added sidebar restore checks to ensure future iPad navigation updates continue to keep the Show Sidebar button working across the full sidebar set.

Added:
Export your complete calculation History as a portable backup, then restore it on another iPhone or iPad.
Backups include your notes, titles, pins, locks, and detailed loan data.
When you restore, missing calculations are added back without overwriting your existing entries.

### 1.2.4 — 2026-07-25

A focused sidebar navigation fix.

Fixed:
• On iPad, every sidebar screen now keeps a direct Show Sidebar button in the navigation bar when the sidebar is closed, including Calculator, Tip & Split, Discount, Loan, Converter, History, and Settings.
• The iPad sidebar control stays in the same top-leading position as it changes between Hide Sidebar and Show Sidebar.
• Added sidebar restore checks so future iPad navigation changes must prove the button still works across the full sidebar set.
