PCalc may not be the longest-lived app in the Apple world (I believe ProVUE Development’s Panorama database for Mac may be the winner at 25 years old), but the scientific calculator app from developer James Thomson is pretty darned close. The Mac version of PCalc will be old enough to drink legally in most states — 21 years to be exact — in December of 2013, and it has a younger sibling in the iOS world that just received a new coat of paint and a major tuneup for iOS 7.
PCalc 3.0 (US$9.99, universal) can now be switched into a new default iOS 7 theme called “Samurai” that brings the thin, flat minimalism of the new OS to light. Other themes that you’ve grown used to in the past are still available, however.
But the looks aren’t all that have changed for PCalc. On the iPhone, there’s now a “smarter display” that uses a larger font size for entries and results if there are fewer lines of data to display. That should make it much easier to read numbers on the small screen as you’re using a Lorentz Transformation to calculate tips at your favorite restaurant.
The list of improvements goes on and on, so I’ve added them to the “Press Release” button below. If you need more than just a four-function calculator for your favorite iOS device, definitely check out PCalc 3.0. And if you’ve been using PCalc for iOS, be sure to load the update as soon as you can.
