About this app
Calculator is the scientific calculator Android was missing — a modern, meticulously crafted math workbench that replaces every calculator app on your device.
From a quick arithmetic check to solving quartic equations, inverting 6×6 matrices, fitting regression curves, or graphing 3D surfaces, Calculator handles it all with a single fluid interface.
■ BASIC & SCIENTIFIC
• Clean keypad with smart parentheses
• Trigonometric functions: sin, cos, tan and their inverses
• Natural log (ln), common log, powers, and roots
• DEG / RAD / GRAD angle modes
• Engineering notation via EXP
• Answer recall (Ans) and calculation history
• Fraction input with dual entry modes (a/b)
• Thousand separator toggle
■ EQUATION SOLVER
• Polynomial equations up to quartic
• Simultaneous linear equations (up to 6 variables)
• Inequality solver
• Ratio and proportion solver
• Precise numerical results with adaptive tolerance
■ MATRIX & VECTOR
• Matrices up to 6×6
• Determinant, inverse, transpose
• Row-reduced echelon form (RREF) and rank
• Addition, multiplication, and matrix power
• Vector arithmetic, dot and cross products
■ STATISTICS
• Single-variable and two-variable datasets
• Mean, median, mode, variance, standard deviation
• Linear, quadratic, logarithmic, exponential regression
• Correlation coefficient and R²
• Probability distributions
■ GRAPHING TOOL
• y = f(x) Cartesian plots
• r = f(θ) polar plots
• x(t), y(t) parametric curves
• z = f(x, y) 3D surfaces
• Root finding, extrema, and definite integrals (area)
• Pinch to zoom, drag to pan, trace values
■ CONVERTERS & CONSTANTS
• Base converter: Bin ⇄ Oct ⇄ Dec ⇄ Hex
• Bitwise operations (AND, OR, XOR, NOT, shifts)
• Unit converter: length, mass, temperature, area, volume, speed, time, energy
• Built-in physical constants
■ BEAUTIFUL DESIGN
• Material 3 interface with refined typography
• Light, Dark, and System themes
• Subtle haptic feedback
• Full accessibility support with content descriptions
• Landscape and foldable friendly
■ PERFORMANCE & PRIVACY
• Native Kotlin — instant launch, instant results
• 100% offline. No account, no cloud, no tracking
• No personal data collected
• Compact install footprint
■ AD-FREE OPTION
