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.

Best SIMPLE NO AD calculator for iPhone

I had been using the iPhone calculator app but it lacked the back button and history. So I began looking for a replacement. Other calculator apps are way too complicated for basic use and are meant for math students, or if they were simple they had annoying ads. This one is the only one that had everything I was looking for! I love the little sound the keys make too. It’s a nifty cute calculator that doesn’t have fancy gimmicks that get in the way. So happy with it!

Great App No Ads

This calculator does a good job of showing you all calculations so you can check your work. I had been using another one with ads and it was so distracting.
It’s easy to edit or clear long calculations.
Best app I’ve found.
Again no ads. I would always lose my train of thought with this other app and have to start over with ads for like the most random stuff. Can’t express how great of a find this is.
Relieves my anxiety! And does a great job.
