Calculator

Bring a little focus to everyday numbers. Calculator pairs a cinematic charcoal-and-copper design with clear controls for daily calculations. Work through a quick total, check a percentage, or open the scientific keypad when you need more. EVERYDAY CALCULATIONS Add, subtract, multiply and divide with a live result preview. Use decimals, parentheses and the change-sign key to build your expression. Standard operation precedence helps you calculate multi-step expressions clearly. PERCENTAGES THAT FIT DAILY LIFE Calculate discounts and increases directly. For example, 200 + 10% gives 220, while 200 × 10% gives 20. The built-in help explains the percentage behavior. SCIENTIFIC TOOLS, ONE TAP AWAY Expand the keypad for sine, cosine, tangent, square roots, powers, factorials, logarithms and absolute values. Switch between degrees and radians, use pi and Euler's number, or insert your previous answer with Ans. PICK UP WHERE YOU LEFT OFF Your current expression, angle mode and up to 50 recent calculations are saved on your device. Reopen the app to continue, tap a history result to reuse it, or clear the history whenever you want. Hold a result to copy it to your clipboard. DESIGNED FOR FOCUS Warm copper accents, spacious numerals and a dark cinematic interface keep your calculation in view. The layout adapts to portrait and landscape, with accessible buttons and a separate scientific panel. PRIVATE BY DESIGN Calculator works entirely offline. There are no ads, subscriptions, accounts, analytics or trackers. The app requests no permissions and does not collect or transmit your data. Your saved history stays on your device. CALCULATION DETAILS Calculations use up to 16 significant digits. Scientific functions return approximate values. Invalid operations, such as division by zero or the square root of a negative number, show an explanation so you can correct your input. Available in English. Supports Android 7.0 and later.
