Too hard to read
PCalc is powerful, but the UI is a mess. Themes are bright and distracting, and there’s no way to get simple high-contrast text across the keypad, tape, and buttons. Fix one area and another becomes unreadable. Basic readability shouldn’t be this hard.
The best calculator app
I was looking for a calculator with support for RPN and conversions. This one checked boxes I didn’t even know I had! Amazing customizable interface that’s quick to learn, lots of options, and endless conversions and useful functions. An example of how to make a powerful app that works excellently on an iPhone.

This is the crown jewel, stop looking.
Keeps getting BETTER. Best!
Used for years. Reliable. Simple understandable display. And year after year keeps adding _useful_ features. Latest is woodworking fractions. THANK YOU
Outstanding App
Thanks for all the hard work.
Need a calculator with more features? Look no further.
This is the pinnacle of Calculator apps on iOS. The only way could be better is if I could play games on it, like I did on my old Ti-85 in high school 😉 (check out “About by PCalc“ for some delightful surprises)
I’ve customized my calculator layouts very nicely, though I do wish I could more easily synchronize those (and other settings) between iOS and Mac versions.
Bottom line:
If you ever wished the built-in Calculator app could do a bit more… Or even a lot more, then get PCalc!

Still the best calculator app out there!
Pcalc has been a staple on every iOS device since it was first released. If I had any complaint, the modern LCD font is too bold. We need a standard version of this LCD font too…just sayin. ツ
Hey what up?
Can you guys told me, please, why you erase my microchip icon?
Update ruined it
What did you do with my calculator? I loved this app. The latest update completely changed the look that I now can’t get back. Why?!?
What happened?
Since roughly a year, the widget disappeared & the layout in the app itself looks totally messed up.
Are you going to update this app, or can I deinstall and never bother giving you money again?

What I need.
This has a lot of features, but the features I regularly use are easy to find, and not hidden. It’s great that it’s available on all my devices.

This phenomenal app gets used by me daily, I don’t see any possible way it could be any better. Anyone who gives this less than 5 stars has completely lost their mind!
Love it!
This review is from my son who loves this app too! He has requests: Can you please add a ton of more customization options for examples change the shape of the buttons of the calculator and please add the option to change the color and choose your custom gradient of the numbers on the calculator and add custom gradients for the calculator and please add an option to choose your background of your calculator and please add an option to make the calculator in a outline border and add more font options and add more swiping gestures for example 2 3 or 4 finger to swipe up down left right for actions

Great
Everything I want in a calculator, plus more. Looks beautiful, and I can customise the keyboard.
hex limited to 48 bits in a 64 bit era
why the limitation?
Fantastic calculator
It’s a great calculator that has so much flexibility. Hats off to the developer. I only wish the universal purchase included the Mac version. They offer the app on the Mac as a separate purchase. $10 is already on the high end for a utility app (although worth the price). I just can’t bring myself to pay it again to have the same app on the Mac.
