A scientific calculator with a unit converter, calculation history, tip splitting and 16 theme skins. All tools and themes are free to use in this version, with no subscription required.

EVERYDAY AND SCIENTIFIC CALCULATIONS Use arithmetic, parentheses, percentages, powers, square roots, trigonometry and logarithms. Switch between degrees and radians, preview results as you type, edit expressions and reuse values from memory or your previous calculation.

16 THEMES FOR YOUR STYLE Choose cute cats, a corgi, a teddy bear, mecha, racing, camping, planets, neon, retro wood or classic colors. Explore different illustrations, key shapes and materials. Every skin supports light, dark and system appearance and is included in the app, with no separate image downloads.

PREVIEW, TRY AND SAVE FAVORITES Try basic and scientific keys in a complete theme preview. Switch appearance and save favorite skins. Your current look changes only when you choose Apply; preview calculations keep your active expression, memory and history untouched.

UNIT AND CURRENCY CONVERSION Convert length, area, volume, mass, temperature, speed and more. Currency rates show their update time: refresh online or use cached or bundled rates offline. Converted amounts are for reference.

HISTORY, BILL SPLITTING AND DATE TOOLS Search or copy local calculation history and reuse a previous result. Split a bill with tips, or find the interval between two dates for everyday planning.

READY FOR IPHONE AND IPAD Keep the readout and keys close at hand on iPhone. On a wide iPad layout, view your calculations beside history. Everyday math, scientific functions and unit conversion also work offline.

YOUR EVERYDAY PREFERENCES Choose key sounds, haptic feedback and decimal places. Favorites and preferences stay on your device. Available in English, Simplified Chinese, Traditional Chinese and Arabic.
