Copy pasting a number results in zero always?

None of the functions, i.e., +, -, *, /, work when you use a number that you copy then past from?
It always will result in zero when you hit the equal button, =.
What’s going on?
This is a basic function of a calculator in 2021 on a smart phone. 🙄🤷🏾‍♂️

Until this is fixed and I can’t in good faith give it a good rating.
Unfortunate, because the history and back button are helpful.
But I use the copy paste function a lot, and it should work, but it doesn’t.
I can’t be the only one who has experienced this?

Discovered that after pasting, if you then hit the "+/-" button, giving the pasted number a minus, then hit the button again, giving it a positive again, then it will recognize the number as actually being there, as in being recognizable, and will function normally.

That’s the only way to get pasting to work.

Until this is fixed natively I still can’t give it a 5 star rating.
But I have upped my rating from 1 to 3 stars. 👍🏿


The best calculator on iPhone. Period.
Nuff said.
Not to mention the best customer service, all the above issues were fixed after they reviewed a screenviideo sent to them, on request by them, after they must have read my review...awesome.

please send screenvideo to us.

do no get this game at all ,


As I’ve started to get into some more harder math questions, the need for more symbols like square roots is becoming hard to find in calculator apps. So I got this one and it became to my liking. Some stuff you have to pay for which I get; apps need to get money out of it. But these things you need to pay for is if you want a different font and color. One thing I also love is the there are NO ADDS❤️ I have been so tired of trying to look for games and calculator apps that have no adds and especially inappropriate ones, so I was so happy to find out it didn’t.
Also I am not an MPC. This is a real customer.👍

Great free calculator. Funny Hidden glitch 😂

What else is there to say. A free calculator that’s a step up from the iOS version. Scientific advance features, History log, ability to calculate past a billion, no crashes, and little to no ads!!!! Once in a while you’ll get a banner on the top to rate this app or an ad to purchase the premium. Plus got bored and just kept pressing the trash can button and got a funny little glitch. Just keep pressing the button until you can’t anymore. A Calculator with a sense of humor ! Cmon on what else do you need?
