Best simple calculator, and here’s why
4.9/5
"It has full memory buttons. There’s no excuse for a calculator not to have them, but many don’t. It also displays the value of the memory which comes in very handy. On top of that, it has easy cut and paste buttons, which also come in very handy. It does not have scientific calculator buttons except for square root, but 99% of the time I don’t need those, and if I do there are countless scientific calculator apps that do the trick but aren’t as good basic calculators."
Great user Interface!
4.5/5
