About this app

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 ($1.99/month or $9.99/year). Payment is charged to your Google Play account. Cancel anytime in the Play Store.
