User Reviews for PCalc
Super Happy HP 48G User 😊
*Finally* found a great calculator! 🧮🙏🏼I’m a chemist 👨🏻🔬, used to using an HP 48G, and simulators for that have come and—sadly—gone. 😱😭 This one’s not a simulator, but has numerous, super thoughtful settings that (among many other options) allow you to set it up in a way that’s very familiar and useful for people accustomed to the HP 48G—or whatever other system you’re used to. (Just for calculation functions; for programming and graphing, probably look elsewhere.) For those who prefer not to use RPN, no problem: standard notation is default.Unlike Calcularium—which I’ve been using, but has become unusable since iOS 14—PCalc starts right up without communicating with the mothership 🛸 or any other delay or funny business, and accepts input and works *fast*. Units conversions are a breeze.You can edit button functions! Also edit: visible stack levels, digit color, font (I like LCD Bold), precision, etc. Choose light and dark themes (I like Flynn with Dark Orange digits) and app icon (I like Circuits).The Apple Watch app features a nice tip calculator.On the iPhone, this app enjoys pride of place, close to my right thumb, among my Camera, Chrome, and Calendar.Cheers! 🍻
Just like your default calculator! Do not buy!
I am disappointed in. Is app. This app was in the App Store for the Apple Watch and I thought it could do the scientific calculations from the Apple Watch but you can’t. You can only do simple math problems with multiplication, addition, subtraction, division and tip calculations, etc,. I thought that it could perform scientific calculations on the watch (since it was in the Apple Watch App Store) but that’s only if you used you iPhone which is stupid because your iPhone can already do that out of the box. I think this app is well overpriced and it doesn’t offer any special features to carry a price tag of $9.99. I wished that I could get my money back. It can’t even do simple currency conversions! It’s just an overpriced calculator app that I’ll never use on my iPhone 10s because I’ll just use the default calculator.
It can be anything you want it to be
I have downloaded (and bought) many iPhone calculators and PCalc is by far the best. The depth and breadth of this app is a true labor of love by the author who has spend decades perfecting it (see his website). As an RPN lover and HP calculator addict, I have searched for and tried most of the offerings in the app store only to be disapointed by the rediculous skeuomorphic designs that abound.With PCalc, the amount of custimization possibilities is dizzyingly vast but, once the shock of available options wears off, you are rewarded with a true sense of empowerment. Case in point: I love the elegance and simplicity of the original HP35 from 1972. I was able to duplicate this keyboard layout and, with the appropriate theme, I was able get it looking very nice. This took me a while but my layout is automatically saved to iCloud where it syncs with my other iOS devices.The layout customization is very sophisticated, allowing you to have keys that are hidden until the 2nd key is pressed. All the labels for each key can be set to whatever you want. I'll stop here not because there is not more to say, but because this calculator shines once you start exploring the many options available. The point being, if you don't like what you see in the default layouts, you can make it be anything you want it to be.
Best Calculator I’ve Ever Used
I am a retired biochemist. I used a slide rule for the first 10 years of my career and then the finest HP calculators that were available until I retired. This PCalc is as good or better for my purposes than any other calculator I have ever owned. I use strictly RPN, and there are a couple of quirks that you have to get use to, e.g. you have to use the “swap” key when solving combinatorics with the built in combination and permutation keys, which is anti intuitive, but easy to get use to. Overall this is a really nice calculator and I can recommend it for most common math applications with no reservations.
Needs 64 Bit Support
PCalc is a good app but if it is going to provide number base operations (hex, octal, decimal, binary) then it needs to add 64 bit support. Even cell phones are 64 bit. Software developers work in 64 bit environments while PCalc only provides support for 48 bits. I have emailed the developer at least 4 times since 2011 and still no 64 bit support. Lack of 64 bit support is inexcusable in this day and age. The best calculator for iOS bar none is free and the name of the app is Sci:Pro. It is 64 bit and has everything that you need at no cost. I give PCalc 3 start because it does everything else very well, but if you want to save some money and deal with a very responsive app developer, give Sci:Pro a try.
Amazing, but missing construction support
Such a great calculator, so many options, I really wish I could use it. There is no support for displaying numerals in inches/feet. You can put things in fraction mode, but it gives you answers outside of base 32 like 4/5ths which is really not helpful. if only you could tell it to round to the nearest 8th or 16th, but rounding is based on decimals. You can give it a minimum denominator, but it still displays answers outside of base 32 which is really frustrating when I can make it do radians or binary, but not base 32 fractions which is a number systems that has been around forever. Love the calculator and all the customizable features, but it just won’t do what I need so I will have to stick to my bad construction calculator for the time being.
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.
Incredibly cool, deep and reliable
I’ve found no calculator app even close to this; and I went through a lot of them before finding it.In addition to being a great calculator in general even for long numbers, it has a deep set of conversions, constants and functions.I’ve been using it for years. Works great on iPad, iPhone and even has a Apple Watch app that works.I’ve never been caught upgrading iOS and finding its broken afterwards, unlike way too many apps.I use it so much it’s on my menu bar on my iPad.
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!
