Description

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

E_C,
Love this app, just wish there were more frequent updates
I really dig the approach this app takes to text + free-form calculations. I use Markdown all the time, so that's a bonus, but the app really shines in the way it interprets text and functions in-place. It has far more power under the hood than I could ever use so I only have a few surface-level nitpicks:

* Document management on iOS/iPadOs is clunky.
* I still hit occasional crasher bugs.
* I wish the iOS/iPadOS versions were updated more frequently. I don't think it needs to roll in all the latest platform features, but some bug fixes and polish would be nice.

Breaking bug on iPad Pro 12.9 with keyboard
Calca is one of my favorite apps. I use it regularly on my phone, laptop, etc. I desperately wish I could use it on the iPad Pro with Magic Keyboard folio.

Unfortunately, in that context, I'm usually trying to total line items under a 'total +=' line. For every line item, when I start typing digits, the app highlights the entry as though I'm cutting / pasting and does not permit me to enter amount normally. I can work around it -- to a degree -- by separating each digit with a non-numeric character, but I usually just give up and go to a different machine.

Hoping the developer will see this and determine what causes / resolves the problem. Huge fan, otherwise, and leaving 5 star review because it works on every other device perfectly.
dotHTM,
My go-to app for calculations now.
Calca is my favorite Math program.

The developer's responsiveness on Twitter is amazing.

It has quickly replaced Pacific Tech's Graphing Calculator as my go-to back-of-envelope estimation tool. Soulver never lived long on my Mac or iPhone as the "running total" quickly got on my nerves as being often highly out of context, even for their example support files.

I love how straight-forward Calca is in it's definition of functions and output. I love how well it handles and resolves physical units (so long as unit definitions are declared early).

In a few cases when I got a spinning-beach-ball after mistakenly entering a very large calculation, I just force-quit, and when relaunched, I was only a minute change from recreating my working file again, even though I'd never manually saved the new "untitled" file.

I really appreciate it using built-in OS X document features like auto-saving and iCloud. In hindsight Calca feels more valuable than the price in the Mac and iOS App Stores. If the developer ever releases a paid-upgrade, I will happily be one of his first repeat customers.

Much more useful than calculator or spreadsheet
This is easily within my top five favorite utilitarian - ie to do stuff - apps on any platform. I hope the author, at a minimum maintains its currency with now iOS, but preferably continues to revise and expand it.

The design of Calca allows one to do quick one-offs and structured analysis with equal ease. I find it a fine balance between calculator, spreadsheet and a Matlab clone like Simo. Its syntax id straight forward and the WYSIWYG structure of the document lets one explain/notate calculations in place.

For Python programmers, Pyto has an API to access Calca's engine from within a Python program running on an iDevice which has Calca installed.
MasPollo,
What an app!
Great calculator mixed with a Markdown text editor?!? Can life get any better?
Honestly though, I've been using this app since it came out for the Mac and iOS, and it's just fabulous. I happily paid for both, but I completely understand the developer's need to make money and try this new approach. I'm just glad that it's still in active development.
Now having graphs on the iPhone is great, and I LOVE the dark mode!
The holy grail would be a way to handle tabular data in a multi markdown table!
DamnableNook,
Wanted to love it, but implementation disappoints
I love the idea and design of this app. Combining Markdown and Mathematica/Wolfram Alpha presses all the right buttons for me. As soon as I read the app description, I needed it in my life. I was ready to donate before even downloading it.

However, once I downloaded the app, I found it... lacking. The idea is great, but the app is buggy/"quirky". I find myself fighting with the interface, tapping on something over and over to get it to register the right action. The Markdown syntax extensions for doing calculations sounds great, but the app makes it hard to enter the correct equations, and get the desired result.

Even the built-in example notebooks, which should showcase the app's features, don't completely work (one notebook, for instance, uses an undefined variable, causing it to fail to run).

Overall, the quirks and bugs make the app more frustrating to use than not. For now, I'm sticking with Tydlig for interactive, explanatory calculations, and will copy+paste results into my Markdown editor if I need to write up text.
rar745,
Best calculator app for math people.
If you are used to using a text editor, with the tab key and a monospace font, to keep track of things, this app is right up your alley. Stripped down and very powerful, this is exactly what I've been waiting for. I'm sure to tell my friends about it, and I don't mind the pop-ups at all. I wish all app developers would use a donate model. They could actually make a sustainable living that way. Cheers to the developer! I salute you.
fitzlarold,
A welcome (and useful) update!
Great update, lots of added utility! I respect the presence of a polite request for support of development and I actually didn't notice the request in the document list until I actually looked for it. I've seen a couple apps go the route of the optional support and I think it's a good idea.

If I may be so bold, however, I would offer some sort of "perk" for supporters. I defer to the developer's good judgement to decide what that might be.

Great work!

Perfection
I used Tydlig as my go-to for many years, but wanted something a little bit more text based and “functional”. This app is easy to learn and use.

One suggestion: my first “problem” was with a function which I tried to evaluate, but forgot to give it an argument. A tooltip or squiggle suggesting I add an argument might be helpful for novices like me.
ahsodex,
Surprising
I went looking for a good RPN graphing calculator in the App Store. After trying several that I didn't really like I found a review in the web for Calca. It sounded interesting even though it wasn't what I was initially looking for. After using it for a few weeks I continue to be impressed with the visual format and features. It's my new favorite app.
