About this game

Calculate everyday expressions with a clear live preview and a keypad designed for quick one-handed use. Work offline without an account, and keep your calculations on your device.

Basic calculator
Add, subtract, multiply, and divide with decimals, signs, parentheses, and percent values. Edit an expression directly or use the keypad. The preview updates as you work, and pressing equals saves the completed result.

Scientific functions
Calculate powers, squares, square roots, reciprocals, absolute values, trigonometric functions, and logarithms. Choose degrees or radians for trigonometry.

Percentage tools
Find a percentage of a number, calculate the percentage change between two values, or find the original amount before a percentage reduction. Each tool displays its formula and validates the input relationship.

History and pinned results
Review expressions with their results, calculation mode, and time. Reuse an expression for further editing, copy a result, view its details, or remove saved entries. Pin useful results to the home screen.

Personalized display
Choose decimal precision or automatic significant digits, number grouping, light or dark appearance, text size, and optional key vibration.

Calculations and saved history remain on this device. No account or network connection is needed for the calculator's core features. Results are general arithmetic outputs and are not professional advice.
