How to make the most of the iOS Calculator

On the surface, the default iOS Calculator app seems very simple. But, there are a few tricks up the Calculator app's sleeve.

The Calculator app is one of the most basic default apps available on the iPhone. However, the app having infamously never found its way to the iPad isn't the only interesting thing to know about it. As with most apps straight from Apple, there is plenty of hidden utility to know about with the Calculator app.

When opening the app, you're greeted with a basic number pad as well as the most basic functions of a calculator available. Hidden behind this minimal interface is an array of options that make the Calculator app much more than basic.

Deleting minor mistakes

Touch screens can be amazing input devices, but touchscreens can also allow you to make the most minute input mistakes. In the Calculator app, you may be tempted to simply the "C" button after making a mistake and begin typing a number all over again.

Deleting a digit doesn't mean you have to delete the whole number.

However, you do have another option. If you happen to make a minor mistake while punching in a number, you can simply swipe left or right over the number to delete the last digit. No matter which direction you swipe, it will do the same thing. You just need to swipe either on or above the number.

Accessing scientific calculator

Perhaps one of the most well-known tricks of the iOS Calculator is accessing the scientific calculator functions in the app. Doing so is as easy as turning your phone to landscape while in the app.

The Scientific Calculator view can be useful for many functions.

Aside from gaining access to buttons for pi, exponents, and more, entering the landscape version of the Calculator app will also let you enter more digits. While in portrait, the iOS Calculator will only let you enter nine digits. When in landscape, the app will allow you to enter sixteen digits.

Copying and pasting

Oftentimes, the calculation you're making is just one part of something you're working on. For those times, it can be handy to copy your results or paste a number into the calculator. Thankfully, both functions are possible.

Copying numbers from your calculator can be a lifesaver for longer strings of digits.

By simply holding down a finger on the calculated result, or the spot where it would be, you can either copy the present number or paste in a new number. When copying a result, you don't even have to go into the Calculator app itself.

In your app library or on your home screen, you can simply long-press the Calculator app. The resulting menu will allow you to copy the last result from your calculator. It copies whatever is displayed on your Calculator app, so if the last thing you did was punch in a 5, the function will simply copy that 5.

Modify Accessibility Settings

If you need or want some changes to how the Calculator app looks, such changes can be made by modifying the app's Accessibility Settings. Changing the settings simply requires you to set up a per-app settings profile for Calculator in accessibility settings.

Changes to Accessibility Settings can give your Calculator a radically different look.

1. Open the Settings app.
2. Select Accessibility.
3. Select Per-App Settings.
4. Select Add App.
5. Select Calculator.
6. Select Calculator one more time.

Once in the Per-App Settings menu for Calculator, you'll be able to modify the app visually with settings such as bold text or increased contrast. Additionally, you'll be able to make any specific Accessibility related changes to the Calculator app you wish.

With these quick tweaks and commands in your arsenal, Calculator can become a much more useful utility on your iPhone.
