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

Smidigt

Chessrubicon on

Smidigt på alla nivån. Använder ofta i vardags situationer. Chess

Magiskt anteckningsblock

Murbruk on

Sweden

Helt fantastisk liten hjälpreda. Funkar utmärkt för vanliga anteckningar, men ger hur mycket möjligheter som helst utöver det. VARNING: Är väldigt beroendeframkallande.

När du vill skriva och räkna samtidigt

frjo on

Sweden

Använder den för att skriva offerter och annat där man behöver skriva och räkna samtidigt. Markdown stöd, variabler och massa annat bra gör den till en fröjd att använda på båda OS X och iOS.

The joy of calculations

This is an app that I use every day. Every time I am amazed of how usefull it is. Simply brilliant!

Fantastisk app!

Sweden

Äntligen ett sätt att göra uträkningar på ett smidigare sätt än för hand med papper och penna! Beskrivningen gör inte appen rättvisa, man behöver titta på exemplen för att förstå hur smart detta är.

What a great app!

Excellent App

This app is unique and there is nothing else quite like it. I use it in place of Excel when multiple calculations are required along with extensive text. That said, it’s been several years since it’s been updated so I’m concerned the developer may have abandoned the project. Calca is among my core apps so I’d be open to a subscription offering to compensate the developer and ensure it remains sustainable.

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.

No longer usable on iPad

When you're using the Magic Keyboard, you can't type in numbers anymore. Once you type a number, it switches into this weird overwrite mode, where every number you type overwrites the current number. For example, let's say you want to type 1234. You'll type 1, which will appear. Then 2 overwrites 1. And then 3 overwrites 2. And then 4 overwrites 3. So instead of 1234, you just get 4. Useless.

Really a fun calculator, spreadsheet and document in one

This is such a useful app, with text documents coming alive as computational documents. Like a spreadsheet in a way, but in a different medium. Truly wonderful
