PCalc

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.

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.

... 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!

I’ve been using the lite version for a long time but upgraded for a few extra conveniences. I am absolutely blown away by how customizable this app is! I spent quite a while creating what is, for me, the perfect scientific calculator. You can even program your own functions. I’m hard pressed to imagine how it could be better. Here are a few small suggestions. 1. In multi line format, make each line individually configurable. I want items on the stack to be visible but in a smaller font.) 2. For custom key names, support font formatting - esp. supercase, subcase. 3. Make key color customizable. That’s all I could think of. And by the way thanks for your business model - the free lite version is really very good and I appreciate that it wasn’t ad supported which most other apps try to do. That’s an instant delete in my book. Fantastic work and thanks!!

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.
