PCalc is the powerful choice for scientists, engineers, students, programmers, or indeed anybody looking for a feature rich calculator. It includes an optional RPN mode and multi-line display, a choice of button layouts, an extensive set of unit conversions and constants, a paper tape, multiple undo and redo, engineering and scientific notation, as well as support for hexadecimal, octal, and binary calculations.
Includes an Apple Watch app, so you can calculate on your wrist!
Fixed a problem installing the watchOS app on Series 4 watches paired with an iPhone 6 Plus.

Ratings and Reviews
Best Calculator App, Period.
This thing is the Disneyland of calculator apps. The developer is a genius. Every feature you could possibly want, or might one day in the future discover you want, is in here. But none of that vast array of features results in any unnecessary complexity. PCalc is totally user customizable, enabling you to create just the feature set and look and feel that you desire.
Also, every other calc app I have tried has either lagged or mis-registered touches, but PCalc is smooth as silk, which is crucial for a calculator. I never thought I would even review, much less rave about a calculator app, but not only does PCalc work like a dream, but it has such incredible attention to detail and customizability that it's actually a ton of fun just to play around with the endless variations.
But wait, there's more. As if this thing couldn't possibly get any better, in the latest version the developer has added what can only be described as a 3-D graphics wonderland as a hidden bonus. Simply tap the "i" key, then "Help", then "About PCalc" and prepare to be amazed. You just have to try it; I don't want to spoil the surprise.
Sure, there are lots of calculators...
... But none like this! Pcalc has been around for a long, long time and is available on both iOS and macOS. However, the iOS version seems to be getting most of the love from the very talented author, and that's okay by me: I'm more likely to have an iOS device handy these days and I now find excuses to use this attractive and powerful app. I use it daily for various units conversions and general calculating.
I fell in love as soon as I discovered it had an RPN mode. Easily mastered, RPN is intuitive and eliminates any ambiguity over operator precedence in complex calculations. My nearly 40 year-old HP calculator still sits in a lonely drawer; I'd rather use Pcalc, now.
If you have an iPad Pro, the latest release has a delightful Easter egg that demonstrates the considerable computing and graphics power, while allowing the author to show off his programming chops. As an old-timer, I'm impressed!
The calculator app that is actually made by people who care about calculators.
I’ve tried lots of calculator apps.
A calculator is usually one of the first apps that a developer makes because it is relatively easy to make a simple calculator and skin it to look pretty.
This app was not a weekend project or a simple calculator that looks good. This is the calculator app that is made by calculator enthusiasts. The customizability is insanely accessible. Not only can you create entirely new button layouts, but the core functionality can be tuned to fit your workflow.
This app is created and maintained by a developer who uses their passion to directly benefit their customer. I rarely see such dedication towards providing a functional product.
This app even includes settings for Reverse Polish Notation (RPN) calculators. A calculator workflow that is obscure, but loved by many.
I still use Wolfram|Alpha for graphs and really complex stuff, but PCalc offers the best basic calculator option around. Even the widget is well thought-out!
