SymboCalc is a full computer algebra system. Factor a polynomial, solve for x, differentiate, integrate, invert a matrix and graph the result. All on your device.
∫ x² ex dx = ex(x² − 2x + 2) + C
Expand, factor, simplify, partial fractions, polynomial division and trig identities.
Derivatives of any order, definite and indefinite integrals, limits, Taylor series, sums and differential equations.
Solve exactly or numerically, real or complex, including systems of equations.
Determinants, inverses, RREF, eigenvalues and eigenvectors, LU and QR, with symbolic entries.
Functions, implicit, parametric and polar curves, slope fields and 3D surfaces. Find zeros, extrema and intersections.
Regressions, distributions, unit conversion, number bases, finance functions and a small programming language.
Why I built it
I wanted the power of a symbolic calculator on the phone I already carry, with math that looks like math and a keypad that doesn't fight me. One keypad, no modes, and every function has an example you can run.

One that works with expressions, not just numbers. It keeps fractions, roots and pi exact, solves equations for a variable and does calculus symbolically, like a computer algebra system (CAS).
Yes. Indefinite and definite integrals, derivatives of any order, limits and Taylor series, with exact results.
Yes. SymboCalc runs on iPhone, iPad and Mac.
No. It makes no network requests. Everything happens on your device.
No. You buy it once. No ads, no account, no tracking.
Also by me
I also build apps for runners, cyclists, swimmers and triathletes at HeadwindLab.
