We all have our special interests. As an engineer and entrepreneur, one of mine is calculators. I long ago lost track of all the calculators I’ve tried. I only buy maybe one out of 10-20 that I try. This is the ONE calculator that I chose to put on my iPhone’s Lock Screen as my main Go-To calculator. I really appreciate everything about the calculator, but most of all, I appreciate that it is NOT a subscription! I didn’t hesitate to pay for it because we all deserve to be paid for our efforts. As a fellow software developer, I have refused to offer my software on a subscription basis. I respect and appreciate fellow developers who offer a good value to consumers. I hope the developer of this excellent software makes lots of money by offering a great calculator at a reasonable price.

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?EDIT: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. 👍🏿Cheers.EDIT 2: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.

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.👍

I find this calculator does everything I need it to do. It is definitely way way better than the Apple calculator. The only criticism I will make is that the trash delete option should be placed off of the keyboard- maybe at the top of the page somewhere- so that it doesn’t get hit accidentally. I have lost a lot of data due to hitting it accidentally. And even if I try to undo the delete many times the deleted data isn’t there to recover for whatever reason. Fixing that glitch would probably help as well. Creators can also have the app bring up a window to confirm that you want to delete if moving the trash icon isn’t feasible. Calculator would be pretty perfect if the glitch was fixed & that change was made.
