OneCalc+: 올인원 계산‪기‬ 4+

This is definitely the best digital calculator I’ve ever used. It displays step-by-step calculations, which are saved until you’re ready to delete them. And there are more features available than this old guy will ever need or use, but they’re out of the way until you need them. The buttons are large enough to fit my fat fingers, and the calculator is nice looking.

You can use this calculator for free, if you don’t mind watching a short video or two. But, for less than the price of a cup of coffee, you can get the paid version. While I didn’t mind the videos, I paid the small purchase price, because it’s obvious that a lot went into the development this little gem.

Give this great little calculator a test drive. I’m sure you’re going to be happy with it.

This is a feature-rich app that is easy to customize. You won't a better app for $4 than this one! It's only 4MB and doesn't use you as a data mine! It doesn't collect your info. Period. If you're using the ad-supported version it has 3rd party analytics for ad-targeting but if you use the paid version it collects nothing from you. That's really as good as it gets!

The features are great! I love the options for volume, temp, data, currency conversion, etc., the list goes on and on! I would pay $10 for this app!!!

Over the years I have downloaded and tried MANY calculator apps. Occasionally I would aquire a favorite of sorts, but none that would keep me from looking at more. I found this one a couple of years ago and I have never downloaded another. This one is extremely complete and I most highly recommend it.
