  • Great Calculator. Almost Perfect for Scientists

    By Name Already Taken Three Times
    What’s not to love? The “fit and feel” are as good as grabbing a physical calculator. It handles everything and more that you’d expect from a standard scientific calculator and more. The functions and conversions are more useful than you’d think and this single app replaces many other apps on my phone. It’s also one of the few iOS calculators that is just as useful whether or not you fall into the rpn crowd. The real standout is the endless customizations. Custom functions, custom conversions, custom display, even custom key layouts. You can really make it as custom as you need it. This is the heart of making useful to you. You can make it into anywhere from a financial calculator to a carpenters calculator with smart custom functions and layouts. While this calculator has evolved into a useful program, it has a few areas that are lacking in making it a truly amazing scientific calculator. 1. It needs real complex number support. You can do some complex calculations using special functions and multiple registers but it’s extremely clunky and not in line with the ease of the rest of the app. It discourages one from doing complex math that many engineers and scientists deal with. 2. The functions need more flexibility in terms of loops and subroutines. The current functions are fine for simple formulas, but some things (like a root finder) need iterative solvers and the ability to call subroutines. At that point one may say you should use an hp or ti emulator, but those are not nearly as smooth as PCalc. A few more features and it will truly be the best calculator in your pocket.
  • THE best calculator. Bar none.

    By fjpoblam
    Please read the description for all the features. PCalc was the first app I bought when I entered the Apple ecosystem. It is my favorite app, with a permanent spot in the dock on MacOS, iPad, and iPhone. Support is fast and courteous, updates are pleasant surprises rather than fixes. Other apps may be entertaining or serve complex purposes. A calculator is a very basic thing. For that essential, PCalc is what you need. You’ll be glad you bought it.
  • 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!
  • Broken layout on ipad pro

    By TheXash
    The layout is broken on iPad, some of the buttons are at random places, that's been going on for at least a few months. I falled back to use the app in my phone... Just discovered that the lite version with IAP fixed the issue, not sure if the "pro" version will ever see a fix... not really acceptable, the App store is really a shambles since virtually all apps have IAP now :(
  • Wow!

    By SnakeMagnet
    This calculator can be infinitely customized. Keyboard arrangements, constants, functions, and conversions can be setup to whatever I want. I am a very happy user.
  • Yes, I Paid for this App

    By sfwendie
    It does more than I'll ever need, but includes multiple memories, paper tape, RPN toggle, AND a downloadable FREE MANUAL. The manual is understandable. Finally, you can slick the interface down so you have a clean screen with the tools you don't need stashed out of the way (I dislike doitall on one screen Cuz it's cluttery). Well, a last comment: I love the 42 homage to Douglas Adams answer to "life, the universe and everything 😎
  • Well Designed App

    By JQKY
    Update: 4/14/18 One suggested improvement: the ability to edit a tape of entries would be sweet. There are a few calculators in the App Store that offer this function. When I need it, I move away from PCalc. Would be nice to have it here. That feature would make it a perfect app for me. Suggested the feature to the developer about a year ago. Don’t ever see it happening. That said, it is still a fantastic calculator app. PCalc has more functions than I will ever use. Pleasing UI on both iMac and iOS 8. It is the only calculator that I use both on my computer and phone. One suggested improvement is to develop an Air Print procedure for quickly printing a register tape. I can cut and paste to MS Word, but it would be helpful to reduce the number of steps for a fast print. This did not warrant dropping a star because the developers really got this app right. Well done!
  • Not a 64-bit calculator

    By SolarWind
    I used to use and enjoy this app but I’m removing it now because it doesn’t allow 64-bit calculations in hex (at least). It is limited to 48-bit hex — not sufficient for my needs. I need a 64-bit hex/binary calculator now and may well need 128-bit within a year or less.

    I typed 5318008 and when I flipped it it said censored.
  • The Swiss knife of calculators

    I just had to convert dollars to zlotys. What a brilliant interface. I love the way you can jump between currencies. Will add item to my calendar to send periodic tips.
