A pink pig calculator with scientific functions, Dynamic Island and interactive Home Screen widgets.
Enable Dynamic Island in the app, switch to another app, then touch and hold Dynamic Island to expand the keypad. A tap opens IslandCalc. A compatible iPhone is required; other supported devices can show the Live Activity on the Lock Screen. The system controls its visibility and duration.
Touch and hold the Home Screen, choose Edit, then Add Widget, and search for IslandCalc. Medium and large widgets support direct input. Small widgets show a result and open the app. Requires iOS 17 or later.
Tap Scientific for trigonometry, powers, roots, logarithms and more. Switch DEG/RAD for degrees/radians, or tap More for additional functions. Equals saves a record; tap a record to continue. Up to 50 records are stored locally.
IslandCalc supports English and Simplified Chinese. It follows your system language. You can also choose a language in Settings → Apps → IslandCalc → Language.
200+10% applies a 10% increase and returns 220. Basic arithmetic uses decimal math; scientific functions have about 15 significant digits. Widget refreshes are scheduled by the system; watch the displayed expression when entering numbers quickly.
IslandCalc does not read other apps, bank data or screen contents. There is no voice recognition; you enter numbers manually.
