What is Calca? Description of Calca

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!

Calculation Features:

• Variables `x = 42`
• Functions `f(c) = 9/5*c + 32` and even recursive functions
• Units `42 mph in kmph` and currency `¥599 in $`
• Solves equations (`x + 2x + 4x = 42`, what is x?)
• Matrices with inverses so you can solve linear equations
• Sum, prod, map, and reduce operations on lists, matrices, and ranges
• Trigonometry and complex numbers
• Derivatives of functions
• Logic operations and if statements
• Binary math (& and |) and support for binary and hex number (`0xA9` and `0b1010`)
• Keeps track of units (m, s, m/s, m/s^2, etc.) so you can verify your equations as you compute

Calca Pros

Easy to useThis has unique combination of having ability to type free text as well as writing and solving math equations. If that is not enough, one can plot them too. A must have..Nickname HolderVersion: 1.5

The calculator on steroids I never knew I neededLike the paper strip in the Mac OS calculator but with a built in time machine that lets you travel back, fix your mistakes and see how your life may have been different. I downloaded this a year ago and fumbled around with it once every few months but never quite understood the point. Today it solved my problem and now that I understand how to use it properly I’ll use it every day. I will miss the debates over rounding rules I have with my colleagues several times a week, I fear this will reduce them to short, calm conversations. They were the best of times, they were the blurst of times. R.I.P..LachlanwgordonVersion: 1.5

Calca Cons

Not supportedApp crashes and it doesn’t look like it’s supported any longer..WeirikVersion: 1.4

Text selection no longer worksUsed to be a dope app. I’m guessing something on the iOS API side broke the old behaviour…. or else the text selection behaviour is just stupid. I have been trying to select BEFORE a number and it keeps incrementing/decrementing the values instead of allowing normal text selection to work..JesusIsRisen69Version: 1.5.1
