Calca is a powerful symbolic calculator that
updates as you type giving you instant answers. It solves equations and simplifies complex expressions. It's also a rich
Markdown text editor so that you can explain your ideas alongside your calculations.

Calca is perfect for
professionals and students - anyone who works with numbers and equations. Variables and functions can be created with
only a few keystrokes and can be manipulated with a rich library of operators and functions.

Calca updates as you
type - just like a spreadsheet. You can declare variables, edit their values and watch everything update before your
eyes. Since everything is calculated on the device - no network needed - you get answers instantaneously.

All
calculations are stored as plain text so you can easily share them with other editors and move them from device to
device. Calca has been designed to work with iCloud documents so all your devices can access your calculations - you'll
always have the latest files ready for viewing and editing.

Calca comes with a suite of examples to help you get
started covering topics from home mortgages to kinetics. All these examples are fully explained within Calca
itself.

Are you still using a desktop calculator? Are you using the silly calculator with the giant buttons that
came with your OS? Computers are much more capable than doing simple one-line arithmetic - put your machine to work with
Calca!
