PCalc’s 25th Birthday →

· · 0 comments

James Thomson is currently celebrating the amazing history of his scientific calculator:

25 years sounds like a really long time. A quarter of a century sounds even longer. Yet, that is how long it has been since PCalc 1.0 was released […]

PCalc was my first ever application. I started writing in the summer of 1992 and it took me around six months to get it into a state where I was happy to show it to the world. Some of that code still runs today, deep at the heart of the machine.

That is both amazing and terrifying.

This means that both the iOS and Mac versions are on sale — down to $0.99 from the usual $9.99.

If you need a really good programmable calculator, do one of two things:

  • wait for the sale to end and buy it at full price (it’s totally worth it)
  • buy it now, go into the About screen, and drop a few coins into the Tip Jar

Wishing you as many more years of PCalc as you want James!

P.S. Don’t forget to play the AR game hidden in the About menu!
