7 Best Free Calculator Apps for iPhone

The calculator app is something we use daily. However, developing a good calculator app is often neglected by device manufacturers, and Apple is particularly guilty of this. Here are some of the best calculator apps for iPhone that we recommend.

The iPad does not have a calculator app, and the one on the iPhone is poorly designed. For instance, it fails to display the operation sign. If you share this opinion and seek a superior calculator app, this article has you covered. Let’s move on to the apps without delay.

1. Calculator & Math Solver – Basic iPhone Calculator With Dictation

Calculator & Math Solver is a simple alternative to the built-in calculator app for iPhone. It provides four tabs: basic calculator, scientific calculator, fraction calculator, and currency converter. One feature we liked is that you can use voice dictation to input equations. It also shows a calculation history to help you keep track. However, only the basic and scientific calculators are free. The currency converter and fractions calculator allow three free calculations, but for more, you need to purchase the pro version.

The pro version of this app disables ads, adds a math problem scanning feature, and allows for custom themes. However, if you only need a basic alternative to the default calculator app, Calculator & Math Solver will do. The app is free, but the pro version starts at $0.99 per month.

2. Quick Calculator Vault Plus – Basic Calculator With a Good History View

Here’s an alternative calculator app that excels in providing a detailed calculation history, unlike the default calculator app. In addition to its simple interface, it offers both a basic and scientific calculator.

It includes options for converting quantities, such as currency, date and time, and geometric dimensions. However, these features are only available in the pro version, which also removes ads.

Overall, we appreciate this app for its functionality. However, if you want a more comprehensive calculator app, you can explore the next few apps on our list. The app is free, but there is also a pro version available for $19.99.

ClevCalc is a favorite iPhone calculator app with a neat user interface. It offers a wide range of calculators, including basic and scientific ones.

ClevCalc offers various calculators such as GPA, loan, VAT, and ovulation calculators. This eliminates the need to search for specific calculators on your browser. You can also customize the themes and startup calculator for free.

There are non-intrusive banner ads at the bottom of the app. The pro version removes ads and the ‘review this app’ pop-up. To try the pro version, you can watch an ad video.

If you find the functions in ClevCalc inadequate, consider the next iPhone calculator.

Price: Free; Pro Version: $7.99

4. OneCalc – Free iPhone Calculator With Better Functions

OneCalc has a comprehensive set of calculators that surpasses the previous app. It includes financial, construction, unit converters, health calculators, and more. Additionally, it has minimal advertisements that do not frequently pop up or interfere with your usage.

OneCalc offers customizable themes and a user interface that resembles the default calculator app. It allows you to set favorite calculators in the ‘fav’ section. However, there are issues with the memory functions, as one function gets cleared when you add another. There are also intrusive ads, which can be removed by purchasing the pro version. Despite these drawbacks, all other features are free, making this app worth trying even in its free version. Price: Free; Pro Version: $3.99.

5. Photomath – Best for Algebra and Other Math Problems

Photomath is one of our favorite apps. It allows you to scan equations using your camera and get results. It also has a good-looking user interface, making it one of the best calculator apps for iPhone.

Apart from scanning equations, you can also upload images or type math problems to find solutions. If you have trouble understanding the solutions, the pro version offers in-depth explanations and animated tutorials. However, the scan-to-solve tool could be faster, so we often find ourselves typing equations instead. Overall, it is more of a novelty feature than a functional one for productivity.

Price: Free; Plus Version: $9.99

6. Graphing Calculator X84 – Best iPhone Scientific Calculator App With Graphs

If you’re a STEM student, chances are you carry a Casio or TI calculator. But what happens when you forget it? There are scientific calculator apps that can help. While they may not have all the features of a physical calculator, they do cover commonly used scientific functions. Graphing Calculator X84 is one such app.

Apart from basic functions, the app also includes a graphing tool. You can plot and share graphs. If you haven’t used a physical scientific calculator, you may not be comfortable with this app’s layout and buttons.

You can enter up to 200 characters for calculations, which should be sufficient for most operations. The app also provides a detailed calculation and function history. It offers options for solving integrals, using statistics and regression functions, and performing logarithmic functions.

However, there are intrusive ads in the app. To remove them, you need to purchase the pro version.

Price: Free; Pro Version: $4.99

7. Panecal Scientific Calculator – A Simpler Scientific Calculator for iPhone

The previous app on this list is designed to be used with a TI 84. However, if you prefer a more generic interface on a scientific calculator and don’t find the app Graphing Calculator X84 appealing, we suggest looking at Panecal Scientific Calculator.

Panecal is a calculator app that meets the needs of users seeking scientific functions on iPhone. It covers mathematical operations and functions found in physical calculators. Configurations and computation modes can be easily adjusted.

However, there are a few issues with calculating inverse operations and the performance is somewhat slow.

A manual is provided to help users understand and utilize the app, which is especially beneficial for first-time users. Unfortunately, the app does not include a graphing feature. The free version offers all important features, but the pro version eliminates advertisements.

Price: Free; Pro Version: $2.99
