The biggest change in 3.9 is support for the user constants, conversions, and functions created by the iOS version of PCalc. You can import them from iOS, and - with the Mac App Store version of 3.9 - they will sync across all your devices automatically via iCloud, both on OS X and iOS. You can also create and edit an unlimited number of user constants using the Mac version, and those will sync too.
Automatic syncing is currently only available in the Mac App Store version, due to Apple's restrictions on iCloud usage, but you can still manually import and export everything. Thanks to Joe Gering who put together a file for all the CODATA 2010 fundamental constants - download this file, double-click it, and PCalc should offer to import it. The list is very long, but you can copy and paste any of the entries into new categories in the Constants section of the Preferences window.
3.9 also adds constant functions in algebraic mode. Just press equals to repeat the last calculation, or enter a new value and then press equals to repeat it on that value - really quick and useful. That will be making its way to the next update on iOS too. I hope to add user function and conversion editing to the Mac version next time as well.
I hope you like this release - let me know on twitter at @jamesthomson or drop me an email. And, if you really like this update, please consider leaving a review on the App Store - it really helps! Thanks.

PCalc is twenty years old this Sunday! I'll let that sink it a bit...
Yes, the first version of PCalc 1.0 was released for the Mac on the 23rd of December 1992. I'm willing to bet it's older than some of the people using it now... I went back and installed a (virtual) Mac with a fresh copy of System 7 and tried to find the very first version online to install. The closest I could come was 1.0.2 from March 1993, but that's good enough to take some screenshots at least :)
I've written up a brief history of the app here - I hope you enjoy the trip down memory lane.
2nd October 2012
The main new feature in 3.8 is support for the high definition Retina display of the new MacBook Pro, along with compatibility with Mountain Lion. You can now save the tape again in the App Store version too.
I hope you like this update - if you do, please update your review on the App Store, or even write one! Reviews are a big part of getting people to buy the app, so thanks in advance.

That's the Mac App Store version of 3.7.1 up now - sorry for the delay, it took 16 days to get reviewed by Apple. I think there are a lot of Mountain Lion updates out at the moment!
The MAS version is now sandboxed which is good from a security point of view, but it's also lost a small feature for annoyingly technical reasons - you can't save the tape out any more. You can however still copy it to the clipboard. I'm still hoping to come up with a workaround for this, but Apple didn't fix the sandboxing bug in Mountain Lion I'd reported to them.
Next up though will be a Retina display enhanced version - I'm just redrawing lots of art at the moment.
24th July 2012
PCalc 3.7.1 with support for Mountain Lion is now available - well, kind of.
If you bought PCalc via Kagi, you can already download the update here.
The App Store update to 3.7.1 will follow shortly, but it will lag behind by about a week while it goes through Apple's review process. The App Store version of 3.7 runs fine on Mountain Lion, but the Kagi version will get flagged by the new "Gatekeeper" feature as suspicious code, which is why I wanted to get an update out for them now. Thanks for understanding!
The full list of changes is here.
I've also just updated the free Dashboard Widget version of PCalc to work with Mountain Lion too - you can get it here.
20th July 2011
Just a quick note on PCalc and Lion - everything seems to be working perfectly with the latest version 3.7 in my testing. I've been running Lion for some time, and haven't seen any problems. Older versions prior to 3.6.1 may experience problems with the software update mechanism not working, but should be fine otherwise.
PCalc 2.x will not run any more because Apple has removed compatibility with older PowerPC applications. But PCalc 2 is over ten years old, so it's time to update anyway!

"Weighted Calculation Cube"
PCalc 3.7 is out now!
This has a lot of features taken from PCalc 2.4 for iOS, including:
- Quick fraction entry, so you can type 2..3 for two thirds.
- An option for a fixed four register RPN stack.
- An option to set the lower value where scientific notation display starts.
- A new "Lighting" section in the conversions, as well as inch/mm of mercury and water in the pressure section.
- Much faster number entry from the keyboard.
- A great new app icon from PyrusMalus!
The full list of changes is here.
I hope you like it, let me know what you think of the update. Leave reviews on the App Store if you can, it's a great way of getting the word out.
And be sure to check out my Twitter feed at @jamesthomson - it's been quite interesting of late!

If you had a problem yesterday with the non-Mac App Store version of PCalc 3.6.1 not quitting on 10.4.11, delete your old copy and download it again - there was a tiny problem with the build that was up there which I've fixed.
This doesn't affect the Mac App Store version, or people with 10.5 or later, so you don't need to redownload unless you saw the problem.
6th January 2011
Happy New Year - lots of changes to announce today!
Firstly, PCalc is now available to buy from the new Mac App Store. And we're nearly halving the price down to $9.99 to match the iOS version.
We can't distribute the Dashboard Widget via the app store, so it's now available to download separately. And we're making it completely free! If you like it, feel free to buy the apps.
You can still buy PCalc via Kagi - find out more details on the Buy Now page - and updates will of course continue to be available to those who have purchased that way. I think most people are going to be buying via the Mac App Store as time goes on, but it's still early days so we'll definitely be supporting both for the forseeable future.
Brave new world...
30th July 2010
Notable enhancements include:
- Dozens of new unit conversions, including all the currency conversions from the iPhone/iPad version.
- A number of new functions including a mod operator.
- Two new stylish calculator themes.
- Various fixes, not least of which is that copy and paste in the Dashboard Widget is now finally working again!
The full list of changes is here.
This is a free upgrade for existing registered users of PCalc 2 or 3. Aren't I nice?
11th June 2010
PCalc for the iPad has just been released!
26th January 2010
Both fix some small bugs in the core code, and add a couple of minor features including the ability to avoid clearing the tape when you hit "AC".
Oh, and needless to say, if there's an Apple tablet announced tomorrow, I'll make sure there's a version of PCalc available for it soon!
28th December 2009
And we're nearly at the end of another year! Thanks to everybody who has bought a copy of PCalc or DragThing in the last year.
Actually, it occurs that we're at the end of the decade too... So make that a thank you for the last ten years!
See you in the future...

Just a quick note to say that PCalc 3.5 is completely Snow Leopard compatible - I've been running it without any problems for a while now. There is a little DragThing 5.9.4 update available for Snow Leopard today though, you can get it here.
13th August 2009
PCalc 3.5 is now available for download here.
As promised, I've moved many the recent features from the iPhone version back to the Mac, including:
- A "2nd" key to show additional functions.
- New functions like hyperbolic trig, hypotenuse, gamma, delta percentage, memory / stack clear, and last x.
- Multiple-memory support.
- Optional HP48-style RPN behaviour.
- Key click sounds.
- Support for regions that use a quote as the thousands separator.
Basically, if you like PCalc on the iPhone, the Mac version should now feel a bit more like home! This is a free upgrade for existing registered users of PCalc 2 or 3.
