Great calculator with History feature!

My favorite part about this calculator app is that it has a history feature. It is difficult to find a decent calculator app that is has the history feature without sacrificing simplicity and still doesn’t have adds. I searched extensively and only found apps that either had adds, were cumbersome and overkill on features, or weren’t any better than the stock iOS calculator. Finally this app checked all the boxes!

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. 👍🏿

Better than apple calculator

Idk how Apple engineers can think a calculator where you can’t see your math is ok. I’m a bit of a math dweeb and I can’t stand that calculator. This one shows your math and your history and has more functions. Gives me piece of mind I’m punching in the right numbers and +-x whatever the case may be I can always check my math. Great calculator and it’s free no adds either
