The best calculator apps for iPad from simple arithmetic to scientific and engineering equations, to full blown graphing functionality!
Just like weather apps, Apple hasn't seen fit to provide a version of the built-in iOS Calculator app for iPad. So, to the App Store! And that's not a bad thing. The Calculator app on iPhone and iPod touch is... serviceable, but the alternatives on the App Store are better in every way. The only real problem is choosing which of the many calculator apps is the best for you. But that's where we come in! Whether you need simple arithmetic or complex scientific equations, here are my favorite calculator apps for iPad!
PCalc is one of the best calculator apps available, period. Not only is it jam packed with features, it's easy to use and has a great interface. PCalc caters to everyone from students to engineers to scientists to pretty much anyone who wants to pick it up and use it. It's got 64-bit support for the iPad Air and iPhone 5s, lots of themes, and other customizations. PCalc has support for accounting mode, RPN mode, and so much more.
If you want the absolute best all around calculator that money can buy, look no further than PCalc.
I like to refer to Souvler as a math journal of sorts. Just start typing out what you know and what you're trying to figure out and more than likely, you'll come to a solution. It's especially great for story problems or for times when you not only have to solve an equation, but remember notes or certain thoughts. That makes it pretty great for students since it doubles as a note taking area all in one.
If you problem solve by thinking things through and jotting down notes, Soulver is what you want.
MyScript takes an interesting approach to solving calculations since it takes written input. This is great for folks who instantly feel overwhelmed by a lot of buttons on a calculator. There's virtually no learning curve with MyScript, just start writing. MyScipt supports basic equations and operations, logarithms, exponentials, brackets, and more. It makes for a great companion for students who are starting to learn equations and factorials.
For those that don't like learning lots of buttons and prefer natural input, there's MyScript.
CALC is one of the most beautifully done calculator apps I've ever seen, hands down. Buying the premium version for $1.99 will unlock all themes and features. At its roots, CALC is a scientific calculator but can also perform currency conversions, unit conversions, and more. This is thanks to the built-in converter that covers over 20 different conversion types. There are also gestures built in so you can easily view a history of your previous calculations.
If you want a basic calculator that's easy to use but has the ability to do harder computations here and there, CALC is a great happy medium with a gorgeous user interface.
Digits is one of the best options when it comes to viewing a history, or what we refer to as tape in the calculator world. It always sits off to the left and the best part is, it's interactive. Make a mistake? Tap the tape to edit it and you're done. No more entering and re-entering long calculations and lists. Digits also lets you share your register tape or print it in just a tap. You can also change the color and layout of Digits to match exactly the look and feel you'd like.
If you want a calculator for adding up expenses or have a need to see detailed history of what you've previously entered, get Digits.
WolframAlpha may not necessarily be a calculator as much as it is a database of knowledge, but that certainly doesn't mean it can't double as one. I've used WolframAlpha as a calculator for complex equations for years. There's also a reason Apple integrated it directly into Siri, because it really is that good. Just choose the type of equation you want to do or enter it into the query bar and WolframAlpha will not only solve it, but spit out details and explanations for you.
If you're a student or want to better understand math theory or equations, WolframAlpha is a must have.
