Ultimate IPhone Calculator
This is the ultimate calculator if you need more functionality than the built in iOS calculator and like and understand RPN.
The financial and scientific calculators work flawlessly and it is easy to swop between them. The negative reviews are from people how don’t know what these calculators are intended for or don’t know how RPN works. Definitely recommend buying them!
Great App
The app works and it’s free that’s all I wanted. Thank you.
HP-12C
This App is a rip off. I paid in full for it and it worked until now where they have reduced the screen size to distract you with advertisements whilst working and worse the app then only works vertically and not horizontally which it is designed for so awkward and difficult. Very disappointing and reflects an unreasonable and greedy service provider.
Ios 13 compatibility
Not working correctly on ios13

Can’t get rid of adverts. Can anyone advise. Other than that I love the app
I don’t like the ads.
I love this app! But with a new phone I now get the annoying google ads, even though I paid NOT to get them. This is an app deleting irritation. Can you tell me how to get rid of these advertisements?
Dad app
This is really poor
app. They make you migrate then charge not with standing the fact that you paid for the previous app. This is really junk in comparison. You can’t make any stings. There is this most annoying loud clicking sound when you use the app with no option to switch it off. You can’t use it in meetings as you will irritate the hell out of the other people in the meeting.
