Scientific Calqon

Exact-math CAS, symbolic calculus with steps, multi-function graphing, matrices, statistics, and unit conversion — in one beautifully fast calculator.

Scientific Calqon is a full scientific calculator, symbolic CAS, and graphing tool in one — built for students, engineers, and anyone who works with math.

EXACT SYMBOLIC MATH (CAS) • Exact fractions and radicals: 1/3 + 1/6 → 1/2, √8 → 2√2 — no rounding errors • Symbolic derivatives (d/dx, d²/dx²) with full chain, product & quotient rules • Step-by-step derivative explanations • Symbolic integrals — by parts, substitution, partial fractions — plus definite integrals • solve: exact linear & quadratic roots, all complex roots of any polynomial • simplify, expand, factor, limits, Taylor series • Natural-language input: just type "derivative of x^2 sin x"

SCIENTIFIC CALCULATOR • Full expression evaluation with correct precedence and implicit multiplication • Trig, inverse & hyperbolic functions; DEG / RAD / GRAD modes • Logs, roots, powers, factorials, nCr/nPr, mod, absolute value • Complex numbers: (2+3i)(1−i), √(−4), e^(iπ) = −1 • gcd, lcm, isprime, mean, median, variance, stddev and more • Memory keys, persistent history, live preview, Ans recall

GRAPHING • Plot multiple functions y = f(x) on a fast, smooth canvas • Parametric x(t), y(t) and polar r(θ) modes • Pinch-zoom, pan, auto grid & labels — export as PNG or PDF

MATRICES & LINEAR ALGEBRA • det, inverse, transpose, rref, rank, trace, powers, products • Solve Ax = b exactly — or detect "no solution" / "infinitely many" • Eigenvalues, eigenvectors, characteristic polynomial • Exact-fraction results throughout

STATISTICS • Descriptive statistics, distributions, and regression

UNITS & CONSTANTS • Converter across 11 categories: length, mass, temperature, time, speed, area, volume, energy, pressure, data, angle • 17 physical & mathematical constants — tap to copy

DESIGN & PRIVACY • Gorgeous dark & light themes with subtle glassmorphism • Works fully offline — no account, no ads, no tracking

FREE & PRO The scientific keypad, single-function graphing, matrices, and unit conversion are free forever. Calqon Pro unlocks the CAS with steps & natural language, statistics & distributions, multi-function graphs & export, and all themes — and everything is free to try for 7 days.

Calqon Pro is an auto-renewing subscription ($2.99/month or $14.99/year). Payment is charged to your Apple ID. Cancel anytime in Settings.
