Good for barbers

Im a barber so I have to add every haircut and this is perfect Bc I can see everything on the screen. And u can keep track for the whole week of everything you added u can also undo, copy + paste, and u can clear history once u want the refresh the screen. A must recommend if you’re adding lots of numbers!

Good, it can be improved.

I use this calculator frequently and normally is pretty good if you are just doing 2 or 3 numbers calculations. The problem comes when you are doing longer calculations. To correct a number or just add a parenthesis to further develop the formula, you have to use the annoying arrows to go from end to beginning and back of your work; one click at a time is just too annoying.

For this reason alone I would not buy the premium calculator to get rid of the equally annoying adds that keep popping up in the middle of your work. I do will have to say that the adds display has improved from a few years back and now you have a close button to close them faster. The arrows are so counter productive and analogue feeling that I may find another calculator app soon.

Great Calculator!!

Great Calculator I really like that it keeps your previous history. Also that you can delete one number at a time if you mess up instead of starting the whole problem all over again.
