Nice and recently improved.
Lots of great functions and I like the retro appearance. The history, functioning like an adding machine tape, is helpful. Calculator has two modes: standard with a history “tape” and a scientific mode with many more buttons that necessarily hide the tape display. Right now app has two different color schemes for the keypad: gray with a few red buttons or black with a few orange ones. Love the black and orange, reminds me of my TI SR40 calculator. (Yes I have one of those and it still works, although the nicad pack no longer holds a charge.)
09APR2020 update. After my complaint about the app being slow, developer made significant performance improvements. Keypad input speed is noticeably improved. Impala also deserves praise for their responsiveness in addition to making some cool apps. Due to the very good recent update, I deleted all of my ramblings about slow apps from this review and changed rating from four stars to five.

I would have given this five stars until...
I love this calculator. It’s perfect. I hated the ads and decided to try other calculators. Nope, this one was truly the best. So I swallowed the $2.99 to get rid of the ads. I got charged and the ads stayed. Now what? I contacted Apple and they said I can get a refund, but I love this calculator. I contacted the developer and haven’t heard from them. Five stars for the app and zero stars for the developer.
Updated review: They responded to my problem quickly and fixed it! Five stars for the app and the developers response time.
Developer Response ,
Thank you for contacting us with this question. If you upgraded to the full version then this downloaded a separate version of the app to your device which has the ads removed. It could be that you are still using the free version, as when you upgrade both versions will be on your device. I recommend removing the free version and making sure only the full version is on your device. If you accidentally remove the full version then you can download this again without costs from the App Store, as long as you use the same Apple ID.
I hope this solves your problem. If you have any other questions or issues in the future, please do not hesitate to contact us at firstname.lastname@example.org
Advertisements in the paid app
I think overall this is a good calculator app that works well and has little to no bugs, but it has two aggravating issues. 1st isn’t a big deal but just is a little aggravating which is that when you open the app it opens as an all black screen with a tiny calculator in the middle and stays like that for up to 3 seconds sometimes 2nd is I’m extremely frustrated that I paid for the full non advertisements version of this app and it still has advertisements in it. Granted you have to click the little “i” icon to launch the advertisements but it is conveniently located right next to the drop down arrow which I use often to look at older calculations iv done and so frequently (because I don’t have tiny fingers) end up hitting the “I” icon which brings me to a whole different page that is (you guessed it) advertisements, lots and lots of advertisements... I really wish at this point I could get my money back for the paid version of this app.
