The world is becoming more digitized and with the advent of smartphones, people are now able to complete tasks that previously required physical labor. In the past, calculations were either done through mental math or a physical scientific calculator. However, today, the majority of people use smartphones to help them with their calculations. The iPhone, iPad, and Apple Watch have various calculator apps that can be downloaded from the App Store.

The calculator app on iPhones is one of the most basic apps, but its functionality is quite impressive. It has both a basic and a scientific mode, which can be toggled by turning the phone into landscape mode. The app is pre-installed on all iPhones and is free to use. The app also integrates with other apps, meaning that calculations can be made while browsing other apps, without having to exit them.

The iPad calculator app is similar to the iPhone’s calculator app. However, it is optimized for the tablet’s larger screen, making it more accessible and easier to use. The iPad app has the same basic and scientific modes as the iPhone app. In addition, the iPad calculator app has a conversion mode, which can be used to perform conversions from one unit of measure to another. For example, currencies, weights, and lengths, among others. This feature is not available on the iPhone calculator app.

Lastly, the Apple Watch calculator app is a simplified version of the iPhone and iPad apps. It is designed for quick calculations on-the-go and allows users to perform basic calculations, including addition, subtraction, multiplication, and division. The app is easy to use, with large buttons that enable users to input numbers and perform operations quickly. The app is also accessible via Siri, Apple’s voice-activated personal assistant.
