About this game

Calculate everyday expressions with a live result preview, a clear keypad, and support for parentheses, decimals, percentages, and the standard arithmetic operators.

Use the scientific calculator for powers, square roots, reciprocals, absolute values, constants, trigonometric functions, and logarithms. Choose degrees or radians for angle-based calculations.

Three focused percentage tools calculate a percentage of a value, apply a relative increase or decrease, or find an original value before a percentage reduction. Each result includes its formula and input relationship.

Review recent calculations in local history, reopen an expression for editing, copy a result, or pin a useful value to the home screen. Your unfinished expression is retained on this device.

Choose 2–12 decimal places or automatic significant digits, with optional thousands separators. Adjust the theme, expression size, and keypad feedback to suit your preference.

Calculations, history, pinned values, drafts, and preferences stay on your device. No account or network connection is required for the calculator. Results are general arithmetic outputs and are not professional advice.
