PCalc

This calculator needs more bits to be useful.

Been using daily on the Mac since 2004 and iPhone since 2008. It knows the numbers and it’s gonna calc then. It will never let me down. It will never tell a lie. And I hope it will never say goodbye and desert me.

RPN Rocks:-))

Top notch calculator, fantastic customizability, great developers! Dev response was to the following: “The current version is completely unusable due to seconds long lag. iPadOS 14.2, iPad pro 10.5". ” Thanks for the response, but uh, now that i went to test it again it worked?! I feel like a kid who asked the teacher for help with a problem, and as soon as the teacher is standing next to the kid the issue has disappeared… I updated to public beta 3 in the last few days, so I'm guessing the issue was with the earlier betas' handling of slide-over multitasking.

...this would get five stars if the interface or documentation were more helpful on how to work with complex numbers! I just can`t figure it out!

Pcalc replaced my HP unit in 2008. No other app besides PCalc gives me the same fuzzy feeling as owning a physical object (e.g. like a HP42). This application is not mere programmed, it's engineered. Engineered with persistence and iterations over 25+ years. Everything you want from a non-graphing calculator is here: Reversed Polish Notation, programmers tools, constants and conversions for any units and the confidence you need in your tools. I would buy an iPhone only running this app as a calculator replacement.

I have used it for several years, and it's just getting better and better.

Half ass app for Apple Watch. Never seen the point of a tip calculator.

This is an excellent calculator. Far better than any other calculator app I have tested. It is an expensive calculator app, but it gives me a lot of value for the money.

An superb app that does its Job, and that you can use it with the notification center is just sweet. It even works in lock screen so you could use it fast and easy. Dont understand Why apple is forcing the developer to change it or take it away. Its so sad actually. Support this Guy that has made this app and buy the full version for his effort. The one app that i Will use everyday.
