I love that this app doesn't have any annoying subscription or purchase requirements. It's just a basic calculator. Except for one big problem, it won't allow you to write any decimals smaller than ".1" and this is extreemly frustrating everytime I try to multiply percentages. I can hit the decimal, but as soon as I try to put a zero in the tens place (or beyond) it just converts the number back to zero and it is so infuriating because I forget it doesn't work until the next time I try to use it and it happens all over again. If that glitch preventing zeros after the decimal point could be fixed I would be ever so grateful and gladly change my rating to 5 stars.
I use this calculator frequently on my iPad (since Apple decided to not include the iOS Calculator on iPads) - this calculator is quite handy. No ads. Once loaded it's similar to the iPhone calculator. Only thing I don't like is the loading status bar at startup. Every time I start it I have to wait a couple seconds to get past the loading screen - this seems dumb to me. Any other app starts up pretty much instantly on my iPad - except this one. Just the same it works great, no ads or subscription, very nice! BTW another review said something about .1 x 10000 didn't calc correctly , hmmm, when I do .1 x 10000 I get 1000 every time, FWIW. 4 stars because of the long loading screen startup delay, if that were not present this app would get 5 stars!
This is a basic, but functional calculator app, works great (exactly that apple should have included with the iPad). Well worth downloading. One minor feature request would be to remove the loading bar on startup. Let’s face it, while as a developer I to love loading bars, a calculator doesn’t need one. When your are doing math on a tablet, it is usually because you need to do it quickly, so not having to wait for the app to reach the end of the bar would be beneficial. To the developer, Thank your for making a good calculator app that isn’t full of advertising, nor does it demand a subscription service.
Finally a full free scientific calculator app for iPad devices. No adds, support basic and scientific mods. includes short and detailed info for each...
