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!



  • 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

    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.

  • 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.

  • Uneeda PCalc. 👏🏼 The ☕️ and 🥓 of apps. Add to your total dock.

    I found PCalc when I bought my first Apple product way back when. Been a loyal fan since. PCalc has a permanent place on the dock of all my Apple devices and keeps me loyal to Apple even more than Apple 🍎 itself does. This time of year we pre-figure taxes, email ourselves and then print the PCalc Tape, and hand it over to our CPA. 💸 Handy. The Hex converter I use daily, for fiddling with CSS and SVG code (often colors or UTF stuff). Tip figuring’s handy when we’re tipsy enough not to do it in our heads. (Get it? Tipsy? Tip? 🥃) Keyboard editing 🆒, icon fiddling 🔄, a game ❇️: all great. But the basic full-bodied calculator 🔢 is the strong point. Worth the full price. The coffee of calculators. Or bacon. That’s saying a lot.
