Excellent choice

There are several “full feature” calculators in the App Store, and this is one of them. PCalc is an excellent choice, if you want a calculator that does number manipulation, this may be the one for you. If you need graphing, or ability to solve quadratic equations, you need to look elsewhere.

What I’d like to see is a user manual as part of the app, not just a link to an online location.

Also, if you do buy the packs, your icon is indistinguishable from the free version. I have all the packs, except the programmer pack (those days are in the distant past for me). There should be a difference in appearance and name - perhaps you can call it PCalc Plus, instead of PCalc Lite, and add the “+” symbol to the icon?

Finally, do the currency conversions get automatically updated? If so, how often? If no, how do you update manually?

James Thomson is a genius

You want to see the real potential of mobile device software? You want to see superior visual aesthetics? Superior app functionality? Superbly intuitive human interface design? Exemplary respect for the user, including first-rate customer support? All of that in single app? Then download p-calc right now, and for God’s sake, pay the man. He’s a very rare talent indeed, and we’d all be the poorer if he decided to go somewhere else to make a living.

iPhone X, iOS 11.x

Orders of magnitude better than the stock calculator and so many others. The option to add only the additional features that one requires make for an affordable, intuitive experience. Look no further if you want an app that is maintained consistently and always works with the latest devices (even the free version without any additional features unlocked) because PCalc Lite delivers. These are the developers that we should support.
