PCalc App Reviews

This is the best calculator app around. It is a combination of a good engineering/scientific calculator and a programmer’s calculator. The stack and RPN features are familiar and comfortable if you are accustomed to HP calculators. The app on Mac and iPhone work the same ways. It is nice to have the same app, regardless of whether I’m using the phone, pad, desktop, or laptop.

A great calculator, but I wish I could add a button to the control center or a widget. Please add that capability.

Modifiable keyboard (main and 2nd), programmable functions, decimal/hex/octal/binary bases, keyboard/result formats for engineering , accounting, scientific, and others. Built-in conversions (pounds to ounces, miles to kilometers, etc). Constants (speed of light, local tax rate, etc). Used multiple times daily. Makes iPad/iPhone a true computer. First app I bought when I first got into Apple in 2004. Favorite of all apps. Does everything a calculator should do, and more. JT is a man with a great

Outstanding fully featured but user mod-able calculator that is useable by a range of users from beginners learning math thru post doctorate mathematicians.

I have used PCalc for years, probably since it was first released, and it’s still the first app I add to my systems when I get a new one, whether it’s the desktop, iPad or iPhone version. Over the years I’ve focused on the developer tools it offers, and scientific functionality, and now it’s currency conversion when we travel. I have never found another calculator that offers the same functionality, and the only thing I wished it could do was graphing of functions.

Simply blows the default iPhone calculator away in every respect. A delight to use.

Wish I could still see an HP skin

...because of the customizability! please implement 64-bit integers, it's kind of sad that the max value shown is 0xffff'ffff'ffff.

Minor bug…the ‘squeak’ key click no longer produces any sound on the PCalc widget. The ‘classic’ key click tone, however, appears to function flawlessly. Go figure…

I’ve been using PCalc for over 15 years. It never lets me down. I’ve only had a problem with it once and it was promptly resolved. Great calculator app!

Had to stop using the app because of excruciating lag. Even entering digits lag. Will use again when fixed. [update] Deleting the app, downloading it fresh, and then resetting preferences fixed it for me. Best calculator!

Suggestion, merge with the macOS app. Having two separate purchases is annoying. I would much rather pay for an upgrade to use on Mac than have two apps. Makes no sense. Good app otherwise

New style widget doesn’t work but old style does in iOS 16. Wish this was more clear in the description. The old style widget can’t be added to home screens and can only show up below all new style widgets on the widget screen. It’s helpful but sub optimal. Will change this to a 5 star review if this all made more clear in the App Store description.

I don't even remember how long I've been using PCalc on my Macs, iPhones, and now the Watch- since its inception. Greatest calculator anywhere, any platform. Support James!

☞ My 1st on all Apple platforms. iOS, iPadOS. Keypads changed with programmed functons (e.g. tax/tip leaving original total displayed, generous tip during Covid19). We use A>B encyclopedia often. Tape’s superb at (¡!) tax time. Nohing like like a thorough calculator to make your device seem more like a COMPUTEr. If I could have *only one* app outside of what Apple provides, PCalc would be it. This developer is a true star ★ . ☜

One of the most useful apps on my phone. I don’t know how people get by with anything less.

Very nice calculator, spinning off the about screen to a new app was smart as it was starting to bloat the calculator which needs to be as fast as possible.

As a kid, do you remember typing 5318008 on an LED or LCD calculator and holding the calculator upside down to read it? If so, try it on PCalc for iPhone. The software team behind this app know all the math jokes. I love it!

Please add the new iOS 15 widget support. It only supports the old widgets and that means it only shows up at the bottom section of the screen. Please refresh the widgets!!

is there any way to make it to where the calculator will give you square roots in radical form other than in decimal form. other than that great calculator

This is my favorite calculator app, and I use it all the time. I especially appreciate the RPN support, since I learned RPN many years ago on an HP-32SII scientific calculator.

This is an excellent and elegant calculator app for the iPad. This completes the iPad. Keep up the good work. Highly recommended!

Always the first always the best. We love you and what you do.

I really like the calculator. It works great in full screen but when I use it side by side with another app the “5” is non-functional. Once I reset the layout it fixed the problem. Thanks!

If you’re looking for a comprehensive calculator app that’s highly customizable, then this is for you. The more you use it, the more you learn about all its capabilities. It’s become one of my most used apps.

After many years of use PCalc is still and always the first/best. Love having RPN available, base conversions, build in constants, etc. Always just works through many versions of iOS.

Dense, sophisticated, yet easy to use. Does everything you would expect from a detailed calculator. Trace all your steps. Plus an underlying sense of fun with hidden surprises.

Their tag like says it all! I’ve been using this for over 5 years now!

555,135.16 - 555,484.20 = -3,49.0399999999

Ran into a problem with the app freezing/lagging and reached out to the dev on Twitter. Got a response very quickly that helped to troubleshoot and solve the problem. Possibly the best app support experience I’ve ever had. Highly recommended!

Nothing but good things to say - outstanding app and a template for how to properly execute software development. My highest compliments to you! David

The answer to “Life, the Universe, and Everything.” Darned near!

This is the last calculator you will ever have to enjoy! It rules all other calculators. I have a few others and they are permanently shelved after using 42. It as simple as that.

Tip calculator function is available on the Apple Watch app -- but not on the iPhone app. Please make this the perfect calculator app by adding a tip calculator with widget support to the iPhone. Thanks!

I love this app. My favorite calculator!

This is the first and only calculator app to get me to retire my HP32s. THE standard.

Supports RPN which is much faster, and has an excellent watch app.

Not only is this the best calculator app, including RPN, but when you get tired of crunching numbers, you can drop bananas on the floor or roll flaming dice. But seriously, this calculator does everything and then some.

I purchased the full version and had a question on some usage. Sent an email through help option and got reply within few minutes. Extremely useful for engineers!

Love the app but often hard to find on my home screen would love an icon that displays to me that this is a calculator app. The 42 and other options leave a lot to be desired.

Swiss Army Knife of Calculators you can literally do anything. This app is great, the developers always quick to respond. Customer Service is wonderful!

No reason to get any other calculator app. This one has every feature you could want and then some. Great support. And it does RPN. Well worth every penny.

I much prefer to launch the calculator from the control panel. Wish I could do it with rpn

Major learning curve to use this app. Want to use a combination function with x and y inputs? Good luck finding out how to enter the variables! The manual is useless and there’s nothing on google or YouTube.

Is that hard to add multi languages support? I can use it in English......... please add Simplified Chinese..
