Pcalc App

Posted onby admin

Earlier today PCalc developer James Thomson was advised by Apple that he'd have to update his app to remove its Today view widget functionality. This comes over a month after PCalc, with exactly that functionality, was approved by the App Store review team and featured by the App Store editorial team. PCalc is pretty much the best all-round calculator app for iPad. For one, it’s a free app that looks a lot like the stock calculator app on iPhones, which is great. Plus, it offers a truckload of features that make it pretty amazing for everyone from the regular joe to a STEM student.

PCalc is ideal for scientists, engineers, students, programmers, or indeed anybody looking for a feature-rich calculator for the iPad, iPhone, or Apple Watch.

It includes an extensive set of unit conversions, a paper tape, an optional RPN mode, engineering and scientific notation, as well as support for hexadecimal, octal and binary calculations.

It's PCalc at your fingertips!

Based on the popular calculator for the Macintosh, PCalc has been redesigned from the ground up to give the best handheld experience.
