## What is IslandCalc?

IslandCalc is a pink pig calculator that puts everyday math within easy reach.

CALCULATE WITH DYNAMIC ISLAND
Start a Live Activity in the app, switch to another app, then touch and hold Dynamic Island to expand the keypad. Enter numbers manually while viewing a bill or shopping list. Dynamic Island requires a compatible iPhone; other supported devices can display the Live Activity on the Lock Screen.

INTERACTIVE HOME SCREEN WIDGETS
Medium and large widgets support direct input without opening the app. The current expression and result are shared across the app, widgets, and Live Activity.

EVERYDAY AND SCIENTIFIC MATH
Use arithmetic, parentheses, percentages, trigonometry, inverse trigonometry, powers, roots, logarithms, factorials, and more. Switch between degrees and radians, enter scientific notation, undo, delete, or repeat the last operation with equals. Basic arithmetic uses decimal math; scientific functions have about 15 significant digits.

KEEP YOUR RESULTS
Press equals to save a calculation. Keep up to 50 records, tap a record to continue, or copy a result.

SIMPLE AND PRIVATE
No account, ads, or in-app purchases. Calculations stay on your device and are not uploaded to developer servers.

Available in English and Simplified Chinese. Requires iOS 17 or later. The system manages Live Activity and widget visibility and updates. IslandCalc does not read other apps or their data and does not include voice recognition.
