Best Apple Watch calculator!!

I have went thru about 6 calculators for my watch and this is the best. First, it is very simple. If I want complex I use my iPhone. Next, the buttons are about as big as possible. But the stoke of genius was adding a tape of the calculation along the top so you can be sure you put in the right numbers.

I’ve looked at a ton of these apps .. this is the best layout for me. All the basic functions on one screen without having to go back and forth ... also handy is keeping the function key a different color after it’s depressed.

The only thing that would make it a bit better would be a horizontal tape at the top.

Terrible!!! Maybe not!!

Well I just wasted $.99!!!!!
On second thought, and after a few minutes this works great I may update this as we go along, so far I would recommend it!
