iPhone Calculator History: How It All Started

When you think about calculators, what comes to mind? Probably something from the 1970s or 1980s. But that wasn’t the beginning of the trend – in fact, it all started with a humble phone. In this blog post, we will explore the history of the iPhone calculator and how it has become one of the most popular and iconic devices on the market. We will also discuss some of the key factors that have contributed to its success.

How the iPhone Calculator Works

The iPhone calculator was one of the most popular features of the original iPhone. The calculator app was first introduced with the iPhone in 2007 and it quickly became one of the most used apps on the device. The calculator was originally a simple addition, subtraction, multiplication, and division app that users could access from any application.

However, over time the calculator has become much more than just a simple app. Today, the calculator is an essential part of the iPhone experience and can be used for a variety of tasks. In this article, we’ll take a look at how the iPhone calculator works and what makes it such a popular app.

How the iPhone Calculator Works

When you launch the Calculator app on your iPhone, you’ll be presented with three options: Addition (with two buttons), Subtraction (with two buttons), and Multiplication (with one button). Each option contains different functions that can be accessed by tapping on the icon in the bottom left corner.

To use the calculator, you first need to enter some basic information including your numbers. To add numbers, for example, tap on ‘Add’. You’ll then be presented with two buttons: one for adding single numbers and another for adding multiple numbers simultaneously. Simply enter your numbers and hit ‘Calculate’ to see your results.

To subtract numbers, tap on ‘Subtract’. You’ll then be presented with two buttons: one for the subtraction of single numbers and another

The History of the iPhone Calculator

The iPhone calculator, which is one of the most popular and iconic apps on the iPhone, has a long and complicated history. The app, which was first released in 2007, began as an offshoot of a project known as ‘Boat’. The boat was an application that let users create and share calculators with other iPhone users.

The calculator was originally developed by Craig Federighi and Tony Fadell, who were both working at Apple at the time. According to Federighi, they “were trying to figure out how to put a number pad on an iPhone.” They eventually decided to create a calculator app because “we saw people using calculators all the time.”

Initially, the Calculator was just an application for displaying equations. However, soon after its release, it gained popularity for its ability to solve equations quickly. In fact, according to Apple’s website, Calculator is still the fastest app in the App Store when it comes to solving equations.

One of the reasons the Calculator became so popular is because it was convenient. It allowed users to access their calculations without having to open another application. Additionally, it had a simple and user-friendly interface.

Today, Calculator remains one of the most popular apps on the iPhone. It is used by students and professionals alike for solving equations and performing other mathematical tasks.

What Happened to the iPhone Calculator?

When Apple released the original iPhone in 2007, one of the signature features was a built-in calculator. But in 2013, after 10 years of use, Apple discontinued the feature. Why?

The story begins with the very first iPhone. The original device had no Calculator app, instead relying on a simple numeric keypad for calculations. When developers started asking Apple for permission to include calculators in their applications, the Cupertino company initially resisted – fearing that users would mistake phone numbers and text messages for mathematical operations.

But when Apple realized that its customers were using calculators anyway (to make appointments or figure out costs), they finally relented and added support for native calculators in App Store applications. And thankfully, this decision paid off: The Calculator app was one of the most popular additions to the iPhone platform over the years.

So what happened to it? After 10 years of being a staple on all iPhones, Apple discontinued the feature in 2013 with iOS 7 – replacing it with new functionality within Siri (the virtual assistant). Perhaps surprisingly, many users weren’t unhappy about this change – given that Siri proved to be more accurate and responsive than the old Calculator app anyway.

How the iPhone Calculator Came to Be

The iPhone Calculator was one of the original apps available on the iPhone when it was released in 2007. It was created by Steve Jobs and Bonnie Cohen-Green, and it quickly became one of the most popular apps on the iPhone. The calculator had a simple interface that allowed users to enter basic arithmetic and trigonometry functions, and it also featured a built-in calculator.

What Can You Do With an iPhone Calculator?

The iPhone calculator was first released in 2007, and since then it has become one of the most used apps on the iPhone. This app has a long history, and there are many things you can do with an iPhone calculator.

One of the most popular uses for the iPhone calculator is to work out math problems. It is a great app for students who need to practice math problems or for parents who need to help their children with their homework. You can also use the iPhone calculator to figure out tips and prices or to calculate percentages and other mathematical expressions.

You can also use the iPhone calculator as a timer. This is helpful if you want to track how long something takes, or if you are cooking and want to know how much time remained until your dish was done.

Another popular use for the iPhone calculator is to digitize images and photos. You can use the app to make digital copies of pictures or to convert pictures from one format to another.


With iPhone Calculator history, we want to take a closer look at how it all started. The very first iPhone calculator was created by John Sculley (now Chief Operating Officer at Apple) in 1983 and was called the ” Scientific Touch Electronic Calculator.” It had no buttons and could only be used to perform basic mathematical operations, such as addition, subtraction, multiplication, and division.
