Panecal Scientific Calculator

This is a really great calculator app for those who need a scientific calculator that does exactly what it’s supposed to do. The layout/looks of this app isn’t as aesthetically pleasing as some other ones, and it won’t solve problems for you. However, if you need a good calculator that has all the functions without having to dig into extra menus, this is for you.

I like the calculator although I sometimes get non-banner ads that appear in the same screen as screen identifying version number and fixes, where this ad reads inside a graphic bubble “iPhone Memory Full. device will not work! Clean”, and appears to be a clickable link in the bottom half of the screen. I have gotten similar messages in other apps also, and the ad is clearly referring to storage and not RAM because it tends to imply photos, files, etc. What the ad says is misleading at best since I have plenty of storage space left (but don’t let most apps access to it). I naturally then think this is some kind of phishing attempt from an advertiser, although I also question whether it is a bug beachside this never appears in the banner ad area, and no other ads ever appear here. The version history page often pops up initially, even when there has not been a recent update. Sorry to post this here, but I do not know how else to get in touch with developers about this. I do like this calculator though.

I like this calculator, does what I need with a straightforward interface. Haven’t bought pro yet but I think I will. I was reading in the pro version about bugs with 172! And 0^0=1 The former seems now fixed and the latter I don’t believe is a bug. The limit of x^x as x tends to 0 would seem correct as 1. The behavior with reduced precision mentioned by another reviewer is annoying as it compounds numerical error. I would agree that if you set 2 decimal places the expectation is a display option NOT a calculation accuracy option. The non displayed precision should be available for subsequent calculations. But overall so far I really like it hence 5 stars.
