OneCalc+ All-in-one Calculator

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

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.

All in one calculator is my favorite.

Ok but not great

I’m going on 4 years using this calculator. The extra functionality for figuring temperatures, distance, etc makes it a an exceptionally useful app.
