As useful and powerful as the iPad is, Apple has made some questionable decisions with the device. Sure, iPadOS 14 made the iPad a lot more like a true computing device. However, iPads still don’t have a weather app or a calculator app built in. That’s weird because calculators are pretty much one of the most basic apps that you’ll find in every device. Even the Apple Watch has a calculator. So, whether you want a scientific calculator, graphing calculator, or just a simple calculator, here are the 10 best calculator apps for iPad.

Best Calculator Apps for iPad

Most people need a calculator app for basic everyday tasks. However, if you’re an engineering student, or in a similar profession, you probably need to work with CAS calculators and graphing calculators all the time. Fortunately there are plenty of choices for scientific and CAS calculators for iPad as well.

In this article, we will take a look at the best calculator apps for iPadOS. We will discuss both regular calculators and scientific and graphing calculators in this list. So you will definitely find something that suits your needs.

1. PCalc Lite

PCalc is pretty much the best all-round calculator app for iPad. For one, it’s a free app that looks a lot like the stock calculator app on iPhones, which is great. Plus, it offers a truckload of features that make it pretty amazing for everyone from the regular joe to a STEM student.

There’s also a unit conversion feature here that can convert the value on your calculator to other units of measurement if you need to.

A bunch of the more advanced features such as Programmer mode and Multiple Line support can be unlocked with in-app purchases. However, functions like scientific notation and calculations can be easily performed within PCalc Lite without any issues.

PCalc Lite also supports iPadOS’ slide over mode, so you can keep the calculator open in slide-over view and bring it up whenever you need it without having to quit the app you’re currently using.

2. Calculator – Pad Edition

If you’re simply looking for the iPhone calculator app on your iPad, this is one of the best apps for that. Calculator – Pad Edition uses a similar UI as the iOS calculator app, which means it fits right in on your iPad.

You get all the basic functions in portrait orientation. However, similar to the iOS app, you can rotate your iPad into landscape mode to get a scientific calculator as well. You can also head into Settings to change the size of the calculator if you want, or just use two finger pinch gestures to zoom in and out of the calculator. Plus there’s a history feature as well so you can see all the calculations and results easily.

What’s more, you get plenty of themes as well, so you can customise your calculator if you want to. However, you will have to make an in app purchase of Rs. 179 to unlock themes.

3. Calcbot

You can also check out Calcbot for your iPad calculation needs. This is a straightforward free calculator app that brings support for regular and scientific calculations to your tablet.

Calcbot also comes with a conversion feature that works similar to PCalc’s system, but you will have to unlock the Pro version of Calcbot to use it. Also, if you want a calculator app with history tape feature, Calcbot has you covered there as well, as long as you’re willing to shell out Rs. 179 for the pro version of the app.

4. Uno Calc

While Calcbot hides the history feature behind the full version, if that’s something you really want without paying, you should check out Uno Calc. This app brings the history feature right beside the main calculator screen making it easy to keep track of your calculations.

Plus, you get multiple calculators in one here. There’s the standard calculator obviously, but you can also switch to the scientific calculator and the programmer calculators. Also, Uno Calc can perform unit conversions, so you’re pretty much covered on all fronts.

Just like PCalc, you can open Uno Calc in slide over as well, making it much easier to access the calculator when you need it and then slide it away once you’re done.

5. Digits

The reason I like Digits is because it tries to make it easier for you to fix mistakes made while entering data into the calculator app.

You get a large number pad to prevent mistakes in the first place, along with common arithmetic and calculator functions right up top. There’s a tape feature here as well, and your calculation history keeps updating on the left hand side of the display so you can quickly look back if need be.

Digits does support additional functionality, including scientific calculation, tape editing, export and sharing in CSV formats, and extensive customisation. However, those features need to be unlocked by purchasing the Pro Upgrade for the app (Rs. 179).

For anyone looking to just get a simple calculator app for basic every day calculations, Digit is a great option.

6. Calculator Pro

Calculator Pro is yet another simple calculator app for basic everyday tasks. Unlike Digits, this app brings a full scientific calculator into the mix as soon as you rotate your iPad into landscape mode.

You get all the usual features here, including a history tape that you can revisit if you need to cross examine your calculations. You can even edit the history tape to make fixes to calculations if needed.

The app also comes with a converter built in that can convert currency, units of measurement, energy, force, and more, making this app a solid option for almost everyone who needs such features.

7. Desmos Scientific Calculator

If you’re a STEM student and you need a full fledged scientific calculator on your iPad, complete with support for variables, trigonometry, fractions and even functions, Desmos scientific calculator for iPad is what you need.

You can do pretty much all your scientific calculations on this app, whether it’s using trigonometric functions to solve equations, calculating permutations and combinations, or even statistics with mean, standard deviations, and more.

You also get support for absolute values, log functions, square roots and x-roots, along with support for degrees and radians for your angles.

8. CAS Calculator

For people who need a graphing calculator instead of a simple scientific calculator, or if you’re looking for a CAS calculator for iPad, this is the app you should check out.

With CAS calculator, you can write your equations and instantly get graphs based on the equation you input. You can even create a table of values for f(x) based on different values of x for an equation.

Obviously, you can also use this app for regular calculations if needed, but it’s aimed towards graphing calculations instead. If you’re in college, or just looking for a graphing calculator for iPad, this is definitely worth your time.

9. Numerical 2

Numerical 2 is a calculator app for iPad that’s a little different. There is no “equals” symbol here. The calculator automatically just solves whatever arithmetic values you put into it, which is a great thing for solving basic arithmetic questions faster.

Numerical 2 makes it easy to keep a running answer for every value you enter into the calculator app, and it’s not a basic calculator either. It does bring support for scientific calculations just like most other calculators do these days.

Within settings you can change themes, turn on auto-brackets, switch between degrees and radians, and enable/disable scientific keys if you want.

You can also use Numerical 2’s iPad widget to calculate on the fly and directly copy solved answers to your iPad clipboard. This is a solid feature that’s really useful.

10. The Calculator

Lastly, if you just want a simple, no frills calculator for simple every day calculations, this might just be the app for you. The Calculator is a basic calculator app with big buttons so you can quickly enter in the data you want to, and get your results.

It does bring additional features like a history tape where you can view your past calculations, copy the results or even copy the entire equation if you want to.

One of the cool things about the app is the voice input feature. You can simply tap on the microphone and then speak the equation you want to solve. That’s pretty neat and it works well enough for simple calculations.

Bonus: Omni Calculator

Lastly, there’s Omni Calculator. Now technically speaking, this isn’t an iPad app which is why this isn’t in the list.

Omni Calculator is a website that has a huge collection of calculators for everything from basic calculations to scientific calculations, construction calculations, and a lot more. If you don’t want to install a calculator app on your iPad, you should definitely take a look at Omni Calculator.
