By TLA Systems Ltd.
Open iTunes to buy and download apps.
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!
What's New in Version 3.5.3
Brand new icon!
Added an option to use E notation for the main display rather than superscript numbers.
Added a unit conversion section to the Apple Watch app.
Added a watch complication to quickly access the Apple Watch app.
Added a quick "Reset All Buttons…" command to the layout editing alert if there are any changes.
Added a warning the very first time you try to switch on RPN mode.
Changed the number entry and delete key behaviour to be more sensible for decimals and exponents.
You can now have eight lines of display on a horizontal iPad Pro.
You can now specify certain settings like RPN mode and number of decimal places separately for the app, watch, and widget.
The display mode setting is now used by the watch and widget.
Moved the watch and widget settings into separate new sections.
Fixed a problem with the theme resetting to "Samurai" if you used the automatic night theme option.
Fixed a problem with the minus sign not always displaying properly with the LCD digit style.
Fixed a problem with hiding the status bar when running in split-screen.
Fixed a problem emailing the tape or registers when you 3D Touch the display to peek at them.
Fixed a problem with the "Use Animations" accessibility setting not applying to the splashscreen.
Fixed a problem with VoiceOver for the tape, registers, and RPN stack.
Fixed a problem with existing numbers not being pushed to the RPN stack when starting a new one with the decimal or "Exp" keys.
Fixed a problem with Handoff from the Apple Watch.
It really is phenomenal how good a calculator app can be. You'd think the basic iOS one would be fine, but it can't hold a candle to PCalc. Every aspect has been meticulously thought about, from the lightning fast launch time to the carefully considered design options. The only thing that could have improved it was a shiny new icon, and now we even have that. Top notch.
Missing key features
Unless I'm missing something, nPr and nCr are both missing. They're included in most (if not all) scientific calculators these days, so it seems like a strange thing to leave out. Also, it doesn't support natural input / display so entering surds etc is a pain.
All in all, I've been pretty disappointed with PCalc. It feels like an old school calculator with some extra scientific functions. I think I'd rather just carry my calculator with me.
Great app, got better.
I've had a long time view of "the stock apps are fine...not good, but fine" but that has been proven drastically wrong. This is now my go-to Calculator app, I love it and highly recommend it.
The new logo is stunning too. Find a high res version if you have the time as the detail is incredible.
