How To Delete a Number in Calculator App With a Swipe


Killian Bell over at Cult of Mac recently discovered a swipe gesture that can be used in the Calcular app that allows you to delete the last entered number.

The gesture is quite straight forward, you can delete the last entered number by swiping from left to right or right to left across the display in the Calculator app.

This is quite useful if you’ve accidentally entered the wrong number. I used to wonder why the app didn’t come with a backspace button to delete the last entered number as it meant you had to clear the display and re-enter the numbers again, which was quite a pain.

Check out the brief demo below of how to use the swipe gesture to delete a number:

You may have noticed from the video that the swipe gesture may not work the first time, but should work in the 2nd or 3rd attempt.

I must admit that it is a little embarrassing when you come across an iOS trick that has been around for a very long time that I didn’t know about.

If you knew about it, then I would encourage you to share such tips in our forums or email them to so we can share it with everyone.

    Damn, this was so obvious, I feel a stupid for not figuring it out.

    Thanks for sharing it though, at least I won’t use the clear button again.

        amazing and i can;t believe i have been using it for 4 years and didn;t figure this ou.

  • wow

    Well, this is the result of app that doesn’t come with ‘help’ section and manual………

  • Kimk69

    Huh, nice. And it actually works from swiping in either direction for me. Can’t believe I never noticed that. Good deal.

    • iPhoneHacks

      Yeah, just updated the post with it.

        Thanks!! So excited to know this. No longer reentering the number again after the mistake.
        I had one more question. Do you know how to move the cursor to a specific spot while typing? Say for example I am typing something long in google search bar, If I want to correct something, I have to delete and again correct the word.

          You can “long press” and slide the round popup window to slide the cursor to where you want. Is this what you mean?

      As a specialist? Where?

      • Chris

        Any Apple store specialist knows this. It’s not new news.

        • iPhoneHacks

          Okay, yeah as I’ve mentioned this has been around for a very long time, probably since the iPhone was launched!

  • Alex Nathan Gerstein

    This has been around for a long time. Have been using it since at least iOS 4.0
