Calca is a powerful symbolic calculator that gives you instant answers as you type. It solves equations and simplifies complex expressions - it's a computer algebra system in your pocket! 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 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!

Bewertungen und Rezensionen
Sehr sehr gut!
War nach fünf Minuten begeistert. Sehr einfach, benutzerfreundlich, intuitiv, funktional und sehr gut durchdacht und umgesetzt. Da steckt noch unendliches Potential in dieser App, daher unterstütze ich das Projekt auch. Ich freue mich auf tolle neue Features! Das wird sicher meine Nummer-Eins Taschenrechner-App!
Very Nice App, but sth. to be improved
This is a very nice app, I love the Function like mathcad, but I have found some Problem with typing Chinese. Wenn I type chinese words, it starts always with one letter. And how can I insert pictures? In the End, I want to join your team to improve this software. Thanks!
Really good textual calculations
Bought the Mac app and got this one free. Amazing bundle as I can even use iCloud to access all my calculations and sheets on all my devices. The only thing that doesn't work week is undo/redo on the Mac. Otherwise no issues. Thanks
