Acron Calculator

Acron Calculator writes maths the way you would write it.

Fractions stack. Roots have a radical over them. An integral looks like an integral, and a matrix looks like a matrix. Nothing is flattened into a single line of text you then have to decode.

A full scientific calculator, on your device

Exact arithmetic, roots, powers, logarithms, trigonometry in degrees or radians, complex numbers, matrices, unit conversion across ten categories, statistics and curve fitting over your own data, user-defined variables and functions. It computes on your device, works offline, and sends nothing anywhere.

Two ways to work

Type it as it looks, or use the RPN stack if that is how you think. Both consoles keep a scrollable tape of everything you have computed, so an earlier answer is always a tap away.

Connect a math server for the hard things (optional, one-time purchase)

Unlock the Wolfram Cloud connector and the calculator can also integrate, differentiate, solve, simplify, take limits and sums, and draw plots — using your own Wolfram account. Your account is between you and Wolfram; Acron never sees your calculations.

Prefer to keep everything in-house? Run the free, open-source acron-math-server on your own computer, or connect to one your school or workplace provides. That option is free and always will be.

Built for the way calculators are actually used

A catalog of hundreds of functions you can browse rather than memorize. A data editor for entering columns of numbers. An equation solver. Constants, variables and functions you define yourself.
