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

Prima Hilfe für Geocaching aber ungepflegt

FuchsVonAnzing on

Germany

Von Soulver (RIP) auf Calca umgestiegen. Koordinatenberechnungen mit Variablen könnte nicht einfacher sein. Aber leider funktioniert weder Google noch Währungsupdate derzeit.

Sehr gute App, aber

Xizzel on

Germany

seit, im wahrsten Sinne des Wortes, keine Updates. Entwickler schon seit mindestens 2018 nicht erreichbar (gebe es hiermit nun auf; 3 Mails pro Jahr ergaben keine Reaktion; Homepage, Forum und Support offline seit 1+ Jahren). Solange die App noch funktioniert ok, aber keinen Cent wert im Moment und nicht die Zeit sich einzuarbeiten!

sieht gut aus

aber ich vermisse eine einfache xy Darstellung von Daten. Ist das möglich? Any way to plot arbitrary xy pairs?

Sehr gut nutzbare App für schnelle

DirkCGN on

Germany

Berechnungen, wenn Excel/Numbers auf dem iPhone zu unhandlich sind. Tolle App, Glückwunsch an die Entwickler.

Sehr sehr gut!

Apljdzgfrfsrujzz on

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

TTau.ge on

Germany

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

Benzy22112 on

Germany

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

Schönes Teil

Ottos iPad on

Germany

Eigentlich 5 Sterne wert! Aber die iPad Version im Moment noch nicht nutzbar, da bei der Eingabe von Werten der Bildschirm springt! Die PC Version läuft dafür perfekt. Bitte nachbessern! Dann gibts volle Punktzahl;)

Good App with annoying bugs

DirkDigital on

Germany

Using formulas in a text editor - Cool. Open documents with markdown support - Perfect. Dropbox integration keeps my documents in sync - I couldn't wish for more. But those bugs, which keep the cursor jumping around are just annoying. This app is very useful, but hard to use. Fix it and you will get a five star rating from me.

Jumps to top of page while typing

Dindhktsvn on

Germany

Completely useless if you plan on using this for anything more than a few lines because every time you type, the window jump scrolls back to the beginning of the page!!! Fix!!
