A mean bug broke into the tip jar in version 3.9 and ran off with the contents! We apologize for the inconvenience.
To make up for it, if you ran 3.9 at any point in the last few days, you'll automatically have something added to the tip jar in 3.9.1 for free, regardless of whether you have previously tipped or not.
Ratings and Reviews
Engineering decimal places
Overall, an excellent calculator app. Will award that 5th star when the Engineering Decimal Places is fixed.
Correct implementation will show the same number of significant digits as specified. The flawed implementation controls only digits after the decimal. Thus the significant digits shown is different depending on value. Very annoying. (See HP for correct approach.)
If this is all that’s wrong, then these folks have produced a top quality product. Hope y’all fix it!
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.
I Purchased PCalc and was immediately impressed. Honestly, this app has no peer. Fully customizable, with deep and thorough functionality, it’s hard to imagine anything could be better. After trying the Lite version I jumped and purchase the additional packs and never looked back. Also, I had reason to contact PCalc with a question and they replied immediately. I was totally impressed. Thank you for a great app PCalc people!
