Calculator: Scientific

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 Enjoy Calculator free with a discreet banner, or remove ads with a one-time in-app purchase. No subscriptions, ever. Whether you're a student tackling homework, an engineer verifying results on the job, or a curious mind exploring mathematics, Calculator gives you every tool in one beautifully engineered app. Download Calculator today — the scientific calculator, reimagined for modern Android.
