Most iPhone users will be aware of their device's built-in calculator, but not everyone will know some of the tricks that you can perform with the app that can save you time. Here are some of our favorite tips.

1. Swipe to Delete Numbers

It's a common misconception that if you type the wrong number into the Calculator app, you have to start the whole sum all over again. Happily, that isn't the case: Simply swipe right or left with a finger across the number display to remove the last number you typed, and repeat the action if necessary to remove several numbers.

2. Scientific calculator

The default calculator app includes a built-in scientific calculator that you can use to perform logarithms, square roots, trigonometric calculations, and more advanced math equations.

To access the scientific calculator, simply rotate your iPhone to landscape mode. If it's not showing up, make sure the portrait orientation lock is disabled in Control Center. To switch back to the regular calculator, rotate your phone to portrait mode.

3. Copy and Paste

You don't need to memorize the results of your calculations to input them into other apps. Use the clipboard functions instead - just long press on the number field to copy or paste the result.

4. Copy Last Result

If you've switched to another app, you can still quickly paste the last figure that you calculated without returning to the calculator to copy it.

Using either a swipe up or a swipe down, launch the Control Center on your iPhone, then long press the Calculator button, and you'll see a handy option to Copy Last Result.

5. Spotlight Calculations

Did you know that calculator functions are built into Spotlight Search on your iPhone?

Simply swipe down from the Home screen to bring up Spotlight, and you can perform basic calculations by typing them directly into the Search field at the top of the screen without having to open the Calculator app.

Didn't know some of those. Siri can do calculations too, but how complex will work? Can you do stuff like cube roots or log?

If you’re looking for something beyond the basic stock calculator, I have been using Tydlig for years and it is fantastic.

I don’t know about anyone else, but the calculator app on the iPhone has been mis-registering touches of numbers (5 in particular) since like iOS 11 or something for me. Makes it a real PITA. Up until then, I had no issues at all. Keep expecting them to fix this.

Did they ever fix the bug with copy/paste to other apps from Calculator where it inserts a bunch of unnecessary zeros after the hundredths column? As I do my finances with that calc, pasting numbers from it has been sometimes a PITA when I have to delete a ton of trailing zeros when I paste it into something else...

3D Touching the Calculator app icon on my iPhone 8 Plus gives me quicker access to the "Copy Last Result" option than using Haptic Touch on any iPhone 11 Pro...😩

Just about every 3rd party calculator app available in the App Store is more useful and nicer to use than the stock iOS calculator app.
Weird how that is

I find the calculator interface so slow it’s almost unusable. It fails to register so many touches it’s a joke. I’m not even sure I can understand the issue because the touchscreen works so well everywhere else it can’t be that...

To be fair I also have issues typing in my lock code too fast and it failing to get all the digits then too so who knows. Wish they’d fix it though!
