I love this calculator! Now in version 4 there were many new items added which makes it more compatible to the versions in iOS 7. It is my calculator since the beginning and so I realized the changes. The big layouts are wonderful for an old guy like me and the themes are very good. I didn't realize any big faults and the saved constants are a big help for me. It is fast, stable and worked in every OS X I ever used. Great! The number of digits could be a little bigger, but 15 is more than enough for the daily use I think. A big thank you to the developer and his continuous maintenance. Danke!

As a long-time user of DragThing, I expected PCalc to be an equally superb application, with support to match. I wasn't disappointed. I loved KoalaCalc, but I prefer PCalc, and it's worth every penny of the modest shareware fee.

Over many years, and many trials, this is the one calculator I come home to. It gives me what I need right there. It has earned a place in my Dock. The iOS version was the 1st app i bought for my iPad. Insanely great. Even worse, the developer is very responsive!

I liked Koala Calc, mentioned by the previous reviewer. I don't recall the specifics of why I stopped using it. I do recall that the latest version is from 2005.

These days I use PCalc. Great features, excellent support, and it is maintained regularly.

The calculator that i prefer is Koloa Calc. It is also free and the numeric entry is easier for me.

But I'm pretty sure development has stopped.
