About this game

Calculate offline with editable expressions, live previews, scientific functions, and flexible number display.

Basic calculations
Add, subtract, multiply, and divide with decimals, signs, parentheses, percentages, clear, backspace, and a live result preview. Continue from a completed result or start a new expression.

Scientific tools
Use powers, square roots, reciprocals, absolute values, pi, e, sine, cosine, tangent, natural logarithms, and base-10 logarithms. Switch between degrees and radians.

Percentage tools
Calculate a percentage of a number, increase or decrease a value by a percentage, or reverse a percentage discount. Each tool shows the input relationship and formula.

Calculation history
Review expressions, results, calculation modes, and timestamps. Load a calculation to edit it, copy a result, or remove individual entries. Clear all history with confirmation, or pin frequently used results to the home page.

Personalize your workspace
Choose automatic or 2–12 decimal places, enable thousands separators, adjust text size, select a light, dark, or system theme, and set key feedback.

Calculations, drafts, history, pinned results, and preferences stay in local app storage. No account or network connection is needed for calculator features.
