OneCalc+ All-in-one Calculator

The best calculator for iOS with lot of conversions & features. Easy to navigate. Worth of buying.

I bought the premium of this. The best ever! I even more amazed on the updated forex rate. Amazing!

Best app!!

Complicated, I keep going back to my free one!

Easy to use and very helpful with so many different ways to use it. Whoever figured this thing out should be commended.

Lot’s of functions - easy to use abd nice features such as the history of calculations. I do have a couple of reservations: the systematic underlying of every number and symbol on the calculator is very annoying abd distracting but it cannot be removed. So the minus sign, for example, looks like an equal sign because it is underlined. The other reservation us the lack of choice of a “skin”. It shouldn’t be hard to add a few.

There should be more background colours for dark mode. The recent one is okay but its too dull and the colours are not too good. Different colours for dark mode are needed. Thank you, Your Customer.

Can’t find the square root button, where is it please?

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.

It is of great use
