SymboCalc

SymboCalc is a symbolic calculator that gives you exact answers, not just decimals.

Factor a polynomial, solve an equation for a variable, differentiate, integrate, invert a matrix, then plot the result... all in one app, all on your device.

EXACT BY DEFAULT

Results stay exact: 1/3 is 1/3, not 0.3333. Radicals, fractions and complex numbers are kept symbolic and typeset as real mathematics, with stacked fractions, proper radicals and matrix brackets. Tap any answer to switch it to a decimal, and tap again to switch back.

ALGEBRA

Expand, factor, simplify, collect, partial fractions, proper fractions, common denominators, polynomial division and GCD, trigonometric expansion and collection.

CALCULUS

Derivatives to any order, indefinite and definite integrals, limits including one-sided limits and limits at infinity, Taylor series, summations and products in closed form, arc length, numeric derivatives and integrals, and differential equations with initial conditions.

EQUATIONS

Solve exactly or numerically, over the reals or the complex numbers. Systems of equations, polynomial roots, and a dedicated numeric solver where you fill in what you know and solve for the rest.

MATRICES AND VECTORS

Determinants, inverses, rank, RREF, eigenvalues and eigenvectors, characteristic polynomials, LU and QR, null space, dot and cross products — with symbolic entries, not just numbers.

GRAPHING

Functions, implicit equations, inequalities, parametric curves, polar curves, sequences, differential equations with slope fields, and rotatable 3D surfaces. Pan and pinch, trace, and find zeros, minima, maxima, inflection points, intersections, tangents and areas. Logarithmic axes and sliders for free parameters are built in.

STATISTICS

One- and two-variable statistics, ten regression models from linear to logistic and sinusoidal, and the normal, t, chi-square, F, binomial and Poisson distributions.

MORE

Unit conversion with dimensional analysis and physical constants. Base and bitwise arithmetic in hex and binary. Time-value-of-money and cash-flow functions. A programming language with loops and conditionals. Tables of values. Saved worksheets you can export as PDF.

BUILT FOR TYPING MATHS

One keypad, no modes. A strip of operations sits above it — solve, factor, expand, d/dx, integral — and the full function browser is one tap away, with an example you can run for every function. The letter keyboard is there when you need a name, and gone when you do not.

PRIVATE BY DESIGN

SymboCalc collects nothing and makes no network requests. There is no account, no tracking and no advertising. Your work stays on your device.
