PCalc - The Best Calculator

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 3.6.4

Added an option to change the app icon on iOS 10.3 or later (if the icon doesn't change on the home screen, restart your device and that will fix it - iOS bug, sorry!).
Along with the ability to change the icon between the existing blue and orange versions, there are nineteen more icons to choose from including lots of colors and some old designs going way back to 1992. To unlock those icons, we've added an optional tip jar.
Since we've never charged for an update, this is an experiment to see if people feel like dropping some extra coins into the jar as a way of supporting the release of new versions. Even if you don't tip, you'll always have the full functionality available.
Added a new "Hot Pink" tint color for the "Samurai", "Samurai Night", and "Backlight" themes.
Now blink the display if you press Equals and the answer is the same as the previous number shown.
Now the change sign button doesn't finish entering a hex, octal, or binary number, so you can keep editing it.
Now supports pasting of Arabic–Indic numerals.
The "TC" button now correctly deactivates 2nd functions.
Fixed a crash when tapping "Reset to Defaults" in settings.
Fixed a crash if you toggled the RPN setting after tapping "Done" in the Advanced section of the settings.

Best Modern RPN app on the store

This is by far the best RPN app I have used - and I have tried many of them.

The programming and function features are easy to use and very powerful. And it feels like it was designed for a touchscreen (which any RPN app based on a physical calculator does not).

The synchronization across devices and Computers works exceedingly well.

Worth every penny.

Works great – now includes new icons!

This app runs circles around any other calculator in the App Store, and is well worth the price. No problem installing it on phone or Watch, also version for TV, and functions great on all devices. App author is very responsive & regularly updates the app with new features. if you run into a problem email or Twitter him instead of writing negative reviews!

The latest update includes 2 free alternate icons and 18 more optional ones that you can use when you tip the author 99¢ or more, which is well worth it.

Best calculator barn none!

Love PCalc! James Thompson, the developer is always open and interactive with the community. I was more than happy to throw a little extra change his way for the icons, having gotten so much use out of the app over the years!

Keep up the great work!
