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

Ottima app

Bigsmith1963 on

Italy

Semplice da usare ma nel contempo potente. Ottima per calcoli veloci e ricorrenti. Qualche tools in più non guasterebbe ma senza appesantire troppo

Crashes

It crashes sometimes and loses documents.

BUG CALCOLO? Numeri Complessi

JackSante on

Italy

Sulla carta è ECCELLENTE, (do 1 stella per essere notato, altrimenti ne metterei 5!) Mi sono trovato a fare un calcolo coi numeri complessi... E qualcosa secondo me proprio non funziona.. Provate: a=10+10i b=20+20i a/b=> (10i + 10)*(20i + 20) a*b=> (10i + 10)*(20i + 20) 1. Non sono calcolati e 2. Sono ENTRAMBI moltiplicati?!? dovrebbe essere: a/b=> 0+400i a*b=> 0,5+0i

Mind-Blowing concept

I defenetly fall in love with your app: I hope that it will become famous and revolution the way we solve a calculus or logic problem with the help of technology

Very good app

Wonderful app, But there are some bugs with ios8

Working and useful but...

In general it’s working and is useful but I find some problems with random and not random crashes. The main issue is when i try to send the email with calculations, in this case the app crashes. Other crashes occurs during typing.

Buona idea, poca sostanza

RatedR988 on

L'idea è buona, ma si rivela essere alquanto inutile viste le poche funzioni disponibili. Peccato, potenzialmente potrebbe diventare un ottimo "matlab portatile".

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.
