United StatesEase of use
I pretty much use this as a tallying Machine when I am making prices in the field. I can save it a certain time and go back and see where I’m at and edit if I need to. Very handy.
United StatesTHE BEST CALCULATOR
I’m old enough to have used adding machines with tapes back in the days. Essentially that is what I was looking for but with couple other options like highlighting the line and incorporating it to the current equation. This is the only calculator that did exactly what I was looking for. It is simple and very intuitive app. I use it all the time. I never use other calculator app unless I need a scientific calculator. I really don’t know how people live without it.
United StatesJust what I wanted
Works perfectly for adding multiple receipts. Allows me to see all the entries and fix any errors without having to re-add everything. Love having a adding machine tape without the paper. Great tool!
United StatesGreat calculator
I had a calculator on my old android which I really liked a lot, but which wasn’t available for the iPhone. This one is just as good and certainly much better than the one that came with the iPhone. Yay!
