7 Best Free Calculator Apps for iPhone

A calculator is something we use almost daily. However, we can all agree that the device manufacturer usually puts little effort into developing a good calculator app – and Apple may be the most guilty of this. So, here are some of the best calculator apps for iPhone that we have to offer.

While the iPad doesn’t come with a calculator app at all, the iPhone app is poorly designed to say the least. For example, the program does not even display the sign of the operation you are performing. So, if you are of the same opinion and looking for the best calculator app, this article will help you. Let’s get to the programs without further ado.

1. Math calculator and solver – basic iPhone calculator with dictation

Calculator & Math Solver is a simple and easy alternative to the iPhone’s built-in calculator. It gives you four tabs, basic calculator, scientific calculator, fraction calculator and currency converter. A feature we liked about this app is that you can use voice dictation to dictate your equations into the calculator.

It also shows you your payment history so you never lose it. However, only the Basic Calculator and the Scientific Calculator are truly free. The rest of them – currency converter and fraction calculator offer you three free calculations. To get more, you need to purchase the pro version.

The app also has several lock screen widgets and includes Apple Watch support. Having said that, there are just too many ads, and there are also complaints about a few scientific conversions not working properly on the calculator.

However, the pro version also disables ads and adds the ability to scan math problems and add custom themes to your calculator. Although, if you’re looking for just a basic alternative to the standard calculator app, Calculator & Math Solver will suffice.

Price: Free of charge; Pro version: $0.99 per month and up

2. Quick Calculator Vault Plus – a basic calculator with a good history view

Here’s another alternative to the basic calculator app. What this app is good at is providing a detailed history of calculations compared to the default calculator app. Apart from that, it has a simple interface that gives you a basic calculator and a scientific calculator.

It has a basic set of options to help you convert quantities. It has a currency converter, date and time conversion, and several converters to help you with geometric dimensions. However, all these features are not free and require the purchase of the professional version. In addition, the pro version also disables ads.

Overall, we like this app for what it does. Although, if you’re looking for a calculator app with more calculation and conversion capabilities, you might want to check out the next few apps on our list.

Price: Free of charge; Pro version: $19.99

3. ClevCalc – Universal calculator for iPhone

ClevCalc is one of our favorite iPhone calculator apps. It comes with a neat, beautiful user interface. The best part of this app is that it gives you a huge number of calculators apart from simple and scientific calculator.

ClevCalc has calculators like GPA, Loan Calculator, VAT Calculator, Ovulation Calculator, etc. and it ensures that you don’t have to search for calculators in your browser when you want to calculate something specific. You can also change themes on this calculator for free as well as change the launcher calculator.

This app has ads, but they are unobtrusive. Also, they are in the form of a banner at the bottom of the program. However, the pro version removes ads and disables the “Check this app” popup. But, if you want to try the pro version before you make a purchase, ClevCalc allows you to access it by watching a promotional video.

However, if you find the list of features in ClevCalc inadequate (it’s not, however), then check out the following iPhone calculator.

Price: Free of charge; Pro version: $7.99

4. OneCalc is a free iPhone calculator with the best features

OneCalc has an extensive list of calculators that surpasses the previous app on the list. It has financial calculators, construction calculators, unit converters, health calculators and more. What’s better is that it has minimal ads. In addition, they do not pop up often and do not interfere with your use.

OneCalc also has the ability to customize the calculator with a set of free themes. What we also like about this app is that the user interface resembles a standard calculator. So, if you don’t want to stray away from dating, this is the app for you. You can also set several favorite calculators in the “favorites” section of the program.

But there are several problems with calculator memory functions where one function is automatically cleared when another is added. There are quite a few intrusive ads, but you can remove them by purchasing the pro version.

However, all other features are free and we are big fans of this app. It’s worth it even if you’re using the free version.

Price: Free of charge; Pro version: $3.99

5. Photomath – best for algebra and other math problems

Photomath is one of our favorite apps on this list. This allows you to easily scan equations with the camera and get results for them. In addition, it has a very nice user interface and undoubtedly makes it one of the best calculator apps for iPhone.

Besides scanning your equation to solve it, you can also upload an image from your gallery. It also allows you to enter a math problem to find its solution if you prefer not to scan the written equation.

However, if you are faced with the problem of understanding the solution of the equation, you will get an in-depth explanation and an animated tutorial for the same. However, this feature is only available in the pro version. The pro version also provides you with solutions for all major math textbooks.

But we’d like the solution scan tool to run a little faster. It takes a while to scan and recognize what you wrote, so we often typed the equation directly. So it’s more of a novelty than a functional feature to improve your productivity.

However, the free version gives you all the other important features and doesn’t come with intrusive ads. So for now we can conclude that this app is a must for anyone who is studying math and wants to use a calculator, especially for algebra.

Price: Free of charge; Plus version: US$9.99

6. Graphing Calculator X84 – the best scientific calculator for iPhone with graphs

If you’re a STEM student, we’re sure most of you carry around a Casio or TI calculator. But what about the day you forgot to take it to your classroom? There are a bunch of scientific calculator programs to help you. Maybe not with all the functions of your physics calculator, but at least for the widely used scientific functions. Graphing Calculator X84 is one of them.

In addition to all the basic features, you also get a graphing tool. You can easily build graphs and share them. As mentioned earlier, the layout of the program and the buttons closely resemble a physical scientific calculator. And for that reason, if you haven’t used it before, you might not feel comfortable using this app.

You can enter up to 200 characters for the calculation, and we are sure that this will be enough for most operations. You will also get a detailed history of calculations and functions. There are also options for solving integrals, using statistical and regression functions, as well as logarithmic functions.

However, this app has quite a lot of intrusive ads. If you want to get rid of them, you will have to purchase the pro version of the program.

Price: Free of charge; Pro version: $4.99

7. Scientific calculator Panecal – simpler scientific calculator for iPhone

The previous application on this list was designed for use with the TI 84. However, if you want to see a more general scientific calculator interface and did not find the Graphing Calculator X84 application appealing, we suggest you take a look at Panecal Scientific Calculator.

Panecal will meet the needs of most users who want to use a calculator with scientific functions on the iPhone. It seems to cover most of the math operations and functions present in a physical calculator. You can also change most of the configurations and calculation modes in the calculator.

However, there are a few issues with calculating inverses on the calculator, and the performance seems a little slow as well. Those were the two flaws we could find.

You will also receive a guide to understanding and using the program. This is something we appreciate, especially for those new to a scientific calculator. However, this program lacks graphics functionality. The free version covers all the important features, but purchasing the pro version will also get rid of the ads.

Price: Free of charge; Pro version: $2.99

This is the end of our list. However, if you have any questions, you can take a look at the frequently asked questions section.
