iPhone / iPod touch
You can buy PCalc on the App Store by clicking here. It costs $9.99 in the US, price varies in other countries. PCalc is a universal app - one purchase will work on iPad, iPhone, and iPod touch. No need to buy an "HD" version!
PCalc requires iOS 6.0 or later.
In the continuing absence of demos or trial periods in the App Store, the idea behind PCalc Lite is to provide something useful and free that's better than the Apple calculator, but which will also drive interest in the full version. PCalc Lite is a great calculator, but PCalc is even better!
You can now purchase all the extra features from the full version of PCalc from inside PCalc Lite. Buy them individually, or buy everything.
