Calculator´

Looking for a calculator app that does more than basic math? Calculator´ is a scientific calculator for iPhone and iPad that shows live results as you type, saves your calculation history, and lets you customize everything from colors to fonts.

Scientific Calculator for iPhone

Calculator´ includes all the scientific functions you would expect — trigonometry (sin, cos, tan), logarithms, powers, roots, percentages, and more — alongside standard arithmetic. Results update live as you type, so you catch mistakes before you finish the equation.

Calculation History You Can Search

Every calculation is saved automatically. You can scroll back to find a result from earlier, or use Spotlight search to find it by number. No more re-doing calculations because you forgot to write down the answer.

Calculator App for iPad

Apple did not include a built-in calculator on iPad for years. Calculator´ fills that gap with full Split View and Slide Over support, so you can do math while working in another app.

Apple Watch Calculator

The app includes a native Apple Watch app with haptic feedback. Quick calculations from your wrist without pulling out your phone.

Custom Themes and Personalization

Change colors, fonts, shapes, and sizes to make the calculator look exactly how you want. Create a dark theme for nighttime use, a high-contrast theme for readability, or something colorful just because you can.

Other Features

• Notification Center widget for quick calculations without opening the app
• Custom keyboard you can use inside other apps
• User-defined functions you can create and share with other Calculator´ users
• Built-in timer for tracking time alongside your calculations
• 3D Touch shortcuts for fast access
